b1b70f6761 [lldb-server] Add setting to force 'g' packet use
Following up on https://reviews.llvm.org/D62221, this change introduces
the settings plugin.process.gdb-remote.use-g-packet-for-reading.  When
they are on, 'g' packets are used for reading registers.

Using 'g' packets can improve performance by reducing the number of
packets exchanged between client and server when a large number of
registers needs to be fetched.

48a50ee034 [android/process list] support showing process arguments
Summary:
The qfProcessInfo and qsProcessInfo packets currently don't set the processes' arguments, however the platform process list -v command tries to print it.
In this diff I'm adding the arguments as part of the packet, and now the command shows the arguments just like on mac.

On Mac:

af1d27e301 [platform process list] add a flag for showing the processes of all users
Summary:
For context: https://reviews.llvm.org/D68293

We need a way to show all the processes on android regardless of the user id.
When you run `platform process list`, you only see the processes with the same user as the user that launched lldb-server. However, it's quite useful to see all the processes, though, and it will lay a foundation for full apk debugging support from lldb.

Before:
```
PID    PARENT USER       TRIPLE                   NAME
====== ====== ========== ======================== ============================
3234   1                 aarch64-unknown-linux-android adbd
8034   3234              aarch64-unknown-linux-android sh
9096   3234              aarch64-unknown-linux-android sh
9098   9096              aarch64-unknown-linux-android lldb-server
(lldb) ^D
```

Now:
```
(lldb) platform process list -x
205 matching processes were found on "remote-android"
PID    PARENT USER       TRIPLE                   NAME

696d3cf8ad [platform process list] add a flag for showing the processes of all users
Summary:
For context: https://reviews.llvm.org/D68293

We need a way to show all the processes on android regardless of the user id.
When you run `platform process list`, you only see the processes with the same user as the user that launched lldb-server. However, it's quite useful to see all the processes, though, and it will lay a foundation for full apk debugging support from lldb.

Before:
```

2b38951799 [lldb] Increase testsuite packet-timeout 5secs -> 1min
rL357954 did increase `packet-timeout` 1sec -> 5secs. Which is IMO about the
maximum timeout reasonable for regular use. But for testsuite I think the
timeout should be higher as the testsuite runs in parallel and it can be run
even on slow hosts and with other load (moreover if it runs on some slow arch).

I have chosen 60 secs, that should be enough hopefully.  Larger value could
make debugging with hanging `lldb-server` annoying.

This patch was based on this testsuite timeout:

8864b4360a Make sure the thread list is updated before you set the stop reason
on a thread.  When talking to some older gdb-remote stubs, We were getting
a stop reason from the stop reply packet and setting it on the relevant
thread before we updated the full stop list.  That would get discarded when
the full list was updated.

Also, if you already have a thread list when you go to see if there is an
Operating System plugin, and you do indeed load a new OS plugin, you have to
re-fetch the thread list or it will only show the raw threads.

1659276bee Support nested target.xml register definition files, lack of reg group markers.
The qemu x86_64 target returns a target.xml register definition file which
includes other xml files and they include others, etc.  Also, the registers
are not put in register groups like lldb wants to see.

This patch (1) puts registers that aren't in a register group in a "general"
register group, (2) change ProcessGDBRemote::GetGDBServerRegisterInfo to
be a method that starts the parsing, asking a recurisve function to fetch
and parse target.xml, (3) adds 
ProcessGDBRemote::GetGDBServerRegisterInfoXMLAndProcess which can recusively
call itself to read and parse included xml files, (4) in addition to expecting
the top-level <target> element (which only happens in the top level xml file),
also an xml file that consists of a <feature> node - read the register 
defintions and includes from that <feature> element.

This applies the same fix that was done in r354106 to the lldb-server
test: bitcasting the string to a bytes object before sending it over a
socket. Since the gdb-remote protocol occasionally contains binary data,
and it does not assign any particular encoding to them, this is the
right thing to do here.

c0e793d654 Work with a gdb-remote target that doesn't handle the
qWatchpointSupportInfo packet correctly.  

In GDBRemoteCommunicationClient::GetWatchpointSupportInfo,
if the response to qWatchpointSupportInfo does not
include the 'num' field, then we did not get an answer
we understood, mark this target as not supporting that
packet.

In Target.cpp, rename the very confusingly named
CheckIfWatchpointsExhausted to CheckIfWatchpointsSupported,
and check the error status returned by 
Process::GetWatchpointSupportInfo.  If we cannot determine
what the number of supported watchpoints are, assume that
they will work.  We'll handle the failure
later when we try to create/enable the watchpoint if the
Z2 packet isn't supported.

Add a gdb_remote_client test case.

df9f796fbb Support nwere versions of the Segger J-Link jtag board software.
Add support in ProcessGDBRemote::GetGDBServerRegisterInfo
for recognizing a generic "arm" architecture that will be used if
nothing better is available so that we don't ignore the register
definitions if we didn't already have an architecture set.
Also in ProcessGDBRemote::DoConnectRemote don't set the target
arch unless we have a valid architecture to set it to.

Platform::ConnectProcess will try to get the current target's
architecture, or the default architecture, when creating the 
target for the connection to be attempted.  If lldb was started
with a target binary, we want to create this target with that
architecture in case the remote gdb stub doesn't supply a
qHostInfo arch.

Add logging to Target::MergeArchitecture.

7a8865cea8 [lldbsuite] Make the names of test classes unique
Summary:
If the names are not unique, the tests overwrite each other's results and logs. This also causes failures on platforms where the files are locked for writing.

The names of the class/test pairs *have to* always be unique. The easiest way to achieve that is to name each class differently (usually the same as the file name).

a95c33f600 Fix deadlock in gdb-client tests
Using a listen queue of length 0 caused a deadlock on my machine in the
gdb-client tests while attempting to establish the loopback socket
connection.

I am not sure if this is down to a different python or kernel version,
but in either case, having queue of length zero sounds like a bad idea,
so I'm bumping that to one (which also fixes the deadlock).

ad9b697898 [lit] Fix several tests that fail when using Python 3 or on Windows
Summary:
1) In logtest.cpp, the name of the file that is reported is not always capitalized, so split the comparison to validate the file (case insensitive) and function (case sensitive) separately
2) Update the gdb remote client tests to work with Python 3. In Python 3, socket sends/receives data as bytes rather than byte strings. This also updates the usage of .hex() - this is no longer available in Python 3, so use hexlify instead

acebc43799 Report more precise error message when attach fails
Summary:
If the remote stub sends a specific error message instead of just a E??
code, we can use this to display a more informative error message
instead of just the generic "unable to attach" message.

I write a test for this using the SB API.
On the console this will show up like:
(lldb) process attach ...
error: attach failed: <STUB-MESSAGE>

if the stub supports error messages, or:
error: attach failed: Error ??

if it doesn't.

When we're dealing with virtual (memory) threads created by the OS
plugins, there's no guarantee that the real thread and the backing

a057877a2e Add a test for setting the load address of a module with differing physical/virtual addresses
Summary:
First attempt at landing D42145 was reverted because it caused test
failures on some android devices. It turned out this was because these
devices had vdso modules with differing physical and virtual addresses.
This was not caught earlier because all of the modules in our tests
either lack physical addresses or have them identical to virtual ones.

In the discussion on the patch, we came to the conclusion that in the
scenario where we are merely setting a load address of a module (for
example from a dynamic loader plugin), we should always use virtual
addresses (i.e., preserve status quo). This patch adds a test to make
sure we don't regress in that direction.

f7174ef573 [LLDB] Fix TestTargetXMLArch's expected arch
Summary:
When running on an architecture other than x86_64, the
target.ConnectRemote() part of the test may add platform information to
the target triple.

It was observed that this happens at Process::CompleteAttach() method,
after the platform_sp->IsCompatibleArchitecture() check fails.
This method then calls platform_sp->GetPlatformForArchitecture(), that
on a Linux machine ends up returning a generic Linux platform, that then
ends up getting added to the original target architecture.

16064d354a Re-land: [lldb] Use vFlash commands when writing to target's flash memory regions
The difference between this and the previous patch is that now we use
ELF physical addresses only for loading objects into the target (and the
rest of the module load address logic still uses virtual addresses).

Summary:
When writing an object file over gdb-remote, use the vFlashErase, vFlashWrite, and vFlashDone commands if the write address is in a flash memory region.  A bare metal target may have this kind of setup.

- Update ObjectFileELF to set load addresses using physical addresses.  A typical case may be a data section with a physical address in ROM and a virtual address in RAM, which should be loaded to the ROM address.
- Add support for querying the target's qXfer:memory-map, which contains information about flash memory regions, leveraging MemoryRegionInfo data structures with minor modifications
- Update ProcessGDBRemote to use vFlash commands in DoWriteMemory when the target address is in a flash region

f1389e9201 Add SBDebugger::GetBuildConfiguration and use it to skip an XML test
Summary:
This adds a SBDebugger::GetBuildConfiguration static function, which
returns a SBStructuredData describing the the build parameters of
liblldb. Right now, it just contains one entry: whether we were built
with XML support.

I use the new functionality to skip a test which requires XML support,
but concievably the new function could be useful to other liblldb
clients as well (making sure the library supports the feature they are
about to use).
