c34698a811 [lldb] Rename Logging.h to LLDBLog.h and clean up includes
Most of our code was including Log.h even though that is not where the
"lldb" log channel is defined (Log.h defines the generic logging
infrastructure). This worked because Log.h included Logging.h, even
though it should.

After the recent refactor, it became impossible the two files include
each other in this direction (the opposite inclusion is needed), so this
patch removes the workaround that was put in place and cleans up all
files to include the right thing. It also renames the file to LLDBLog to
better reflect its purpose.

9a57d1e526 [lldb] Allow dumping the state of all scratch TypeSystems
This adds the `target dump typesystem'`command which dumps the TypeSystem of the
target itself (aka the 'scratch TypeSystem'). This is similar to `target modules
dump ast` which dumps the AST of lldb::Modules associated with a selected
target.

Unlike `target modules dump ast`, the new command is not a subcommand of `target
modules dump` as it's not touching the modules of a target at all. Also unlike
`target modules dump ast` I tried to keep the implementation language-neutral,
so this patch moves our Clang `Dump` to the `TypeSystem` interface so it will
also dump the state of any future/downstream scratch TypeSystems (e.g., Swift).
That's also why the command just refers to a 'typesystem' instead of an 'ast'
(which is only how Clang is necessarily modelling the internal TypeSystem
state).

The main motivation for this patch is that I need to write some tests that check
for duplicates in the ScratchTypeSystemClang of a target. There is currently no
way to check for this at the moment (beside measuring memory consumption of
course). It's probably also useful for debugging LLDB itself.

14735cab65 [lldb] [gdb-remote] Add eOpenOptionReadWrite for future gdb compat
Modify OpenOptions enum to open the future path into synchronizing
vFile:open bits with GDB.  Currently, LLDB and GDB use different flag
models effectively making it impossible to match bits.  Notably, LLDB
uses two bits to indicate read and write status, and uses union of both
for read/write.  GDB uses a value of 0 for read-only, 1 for write-only
and 2 for read/write.

In order to future-proof the code for the GDB variant:

1. Add a distinct eOpenOptionReadWrite constant to be used instead
   of (eOpenOptionRead | eOpenOptionWrite) when R/W access is required.

2. Rename eOpenOptionRead and eOpenOptionWrite to eOpenOptionReadOnly
   and eOpenOptionWriteOnly respectively, to make it clear that they
   do not mean to be combined and require update to all call sites.

3. Use the intersection of all three flags when matching against
   the three possible values.

This commit does not change the actual bits used by LLDB.

bbea361039 [lldb][NFC] Remove all uses of StringRef::withNullAsEmpty in LLDB
A long time ago LLDB wanted to start using StringRef instead of
C-Strings/ConstString but was blocked by the fact that the StringRef constructor
that takes a C-string was asserting that the C-string isn't a nullptr. To
workaround this, D24697 introduced a special function called `withNullAsEmpty`
and that's what LLDB (and only LLDB) started to use to build StringRefs from
C-strings.

A bit later it seems that `withNullAsEmpty` was declared too awkward to use and
instead the assert in the StringRef constructor got removed (see D24904). The
rest of LLDB was then converted to StringRef by just calling the now perfectly
usable implicit constructor.

However, all the calls to `withNullAsEmpty` just remained and are now just
strange artefacts in the code base that just look out of place. It's also
curiously a LLDB-exclusive function and no other project ever called it since
it's introduction half a decade ago.

This patch removes all uses of `withNullAsEmpty`. The follow up will be to
remove the function from StringRef.

CommandObjectTargetCreate does some additional preparation after creating a target

4add853647 [lldb] Improve platform handling in CreateTargetInternal
Currently, `target create` has no --platform option. However,
TargetList::CreateTargetInternal which is called under the hood, will
return an error when either no platform or multiple matching platforms

This patch adds the platform option, but that doesn't solve either of
these errors.

 - If more than one platform matches, specifying the platform isn't
   going to fix that. The current code will only look at the
   architecture instead. I've updated the error message to ask the user
   to specify an architecture.

 - If no architecture is found, specifying a new one via platform isn't

Objective-C that this may resolve.  Everything in the SymbolFile
hierarchy still passes in nullptrs, because we don't have an execution

This replaces the current use of LLDB's own `StringConvert` with LLVM's
`to_integer` which has a less error-prone API and doesn't use special 'error
values' to designate parsing problems.

Where needed I also added missing error handling code that prints a parsing
error instead of continuing with the error value returned from `StringConvert`
(which either gave a cryptic error message or just took the error value
performed an incorrect action with it. For example, `frame recognizer delete -1`
just deleted the frame recognizer at index 0).

[lldb/Host] Improve error messages on unowned read files
When trying to read a core file that is not owned by the user running lldb
and that doesn't have read permission on the file, lldb shows a misleading
error message:

```
Unable to find process plug-in for core file
```

This is due to the fact that currently, lldb doesn't check the file
ownership. And when trying to to open and read a core file, the syscall
fails, which prevents a process to be created.

Since lldb already have a portable `open` syscall interface, lets take
advantage of that and delegate the error handling to the syscall
itself. This way, no matter if the file exists or if the user has proper
ownership, lldb will always try to open the file, and behave accordingly
to the error code returned.

b4a6e63ea1 [lldb/Target] Rework the way the inferior environment is created
Summary:
The interactions between the environment settings (`target.env-vars`,
`target.inherit-env`) and the inferior life-cycle are non-obvious
today. For example, if `target.inherit-env` is set, the `target.env-vars`
setting will be augmented with the contents of the host environment
the first time the launch environment is queried (usually at
launch). After that point, toggling `target.inherit-env` will have no
effect as there's no tracking of what comes from the host and what is
a user setting.

This patch computes the environment every time it is queried rather
than updating the contents of the `target.env-vars` property. This
means that toggling the `target.inherit-env` property later will now
have the intended effect.

This patch also adds a `target.unset-env-vars` settings that one can
use to remove variables from the launch environment. Using this, you
can inherit all but a few of the host environment.

The way the launch environment is constructed is:
  1/ if `target.inherit-env` is set, then read the host environment
  into the launch environment.
  2/ Remove for the environment the variables listed in
  `target.unset-env`.
  3/ Augment the launch environment with the contents of
  `target.env-vars`. This overrides any common values with the host
  environment.

The one functional difference here that could be seen as a regression
is that `target.env-vars` will not contain the inferior environment
after launch. The patch implements a better alternative in the
`target show-launch-environment` command which will return the
environment computed through the above rules.

f9568a9549 [lldb][NFC] Make all CompilerDeclContext parameters references instead of pointers
Summary:
All of our lookup APIs either use `CompilerDeclContext &` or `CompilerDeclContext *` semi-randomly it seems.
This leads to us constantly converting between those two types (and doing nullptr checks when going from
pointer to reference). It also leads to the confusing situation where we have two possible ways to express
that we don't have a CompilerDeclContex: either a nullptr or an invalid CompilerDeclContext (aka a default
constructed CompilerDeclContext).

This moves all APIs to use references and gets rid of all the nullptr checks and conversions.
