7d86ee5ab0 Resubmit FileSystem changes.
This was originall reverted due to some test failures in
ModuleCache and TestCompDirSymlink.  These issues have all
been resolved and the code now passes all tests.

30e6cbfcfc Revert "Use LLVM for all stat-related functionality."
this reverts r297116 because it breaks the unittests and
TestCompDirSymlink. The ModuleCache unit test is trivially fixable, but
the CompDirSymlink failure is a symptom of a deeper problem: llvm's stat
functionality is not a drop-in replacement for lldb's. The former is
based on stat(2) (which does symlink resolution), while the latter is
based on lstat(2) (which does not).

This also reverts subsequent build fixes (r297128, r297120, 297117) and
r297119 (Remove FileSpec dependency on FileSystem) which builds on top
of this.

c29f7ff334 Switch "posix" to the new log channel registration mechanism
Summary:
This also removes magic rename code, which caused the channel to be
called "linux" when built on a linux machine, and "freebsd" when built
on a freebsd one, which seems unnecessary - registering a new channel is
sufficiently simple now that if we wish to log something extremely
os-specific, we can just create a new channel. None of the current
categories seem very specific to one OS or another.

c5f28e2a05 Switch std::call_once to llvm::call_once
Summary:
The std::call_once implementation in libstdc++ has problems on few systems: NetBSD, OpenBSD and Linux PPC. LLVM ships with a homegrown implementation llvm::call_once to help on these platforms.

This change is required in the NetBSD LLDB port. std::call_once with libstdc++ results with crashing the debugger.

bf9a77305f Move classes from Core -> Utility.
This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

3f8c78168e Merge Linux and FreeBSD arm64 register contexts
Summary:
This is a test-the-water change about possibilities of reducing duplication in
the register context definitions.

I've named the new class RegisterInfoPOSIX, as RegisterContextPOSIX was already
taken :(.  The two files were identical except for a fix by Tamas in D12636,
which was applied to the Linux version only, which fixed a discrepancy between
the definitions of fpsr and fpcr on one hand, and all other floating point
register definitions on the other.

Linux test suite still passes after this change. For freebsd, make the floating
point register behavior consistent, but I don't know whether it will be
consistently fixed, or consistently broken. By eyeballing the code, I have a
feeling that a similar fix to D12636 will be required in
RegisterContextPOSIXProcessMonitor_arm64::ReadRegister, but I can't be sure as I
have no way to test it (the assert in that function should fire upon accessing
the registers if it is wrong though).

b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

16ff860469 remove use of Mutex in favour of std::{,recursive_}mutex
This is a pretty straightforward first pass over removing a number of uses of
Mutex in favor of std::mutex or std::recursive_mutex. The problem is that there
are interfaces which take Mutex::Locker & to lock internal locks. This patch
cleans up most of the easy cases. The only non-trivial change is in
CommandObjectTarget.cpp where a Mutex::Locker was split into two.

998bdc5b75 Generalize child process monitoring functions
Summary:
This replaces the C-style "void *" baton of the child process monitoring functions with a more
C++-like API taking a std::function. The motivation for this was that it was very difficult to
handle the ownership of the object passed into the callback function -- each caller ended up
implementing his own way of doing it, some doing it better than others. With the new API, one can
just pass a smart pointer into the callback and all of the lifetime management will be handled
automatically.

This has enabled me to simplify the rather complicated handshake in Host::RunShellCommand. I have
left handling of MonitorDebugServerProcess (my original motivation for this change) to a separate
commit to reduce the scope of this change.

583bbb1dd4 Change over the broadcaster/listener process to hold shared or weak pointers
to each other.  This should remove some infrequent teardown crashes when the
listener is not the debugger's listener.

Processes now need to take a ListenerSP, not a Listener&.

This required changing over the Process plugin class constructors to take a ListenerSP, instead
of a Listener&.   Other than that there should be no functional change.

 - Summary:
      When a trace event is reported, we need to check
      whether the trace event lands at a breakpoint site.

      If it lands at a breakpoint site then set the thread's
      StopInfo with the reason 'breakpoint'. Else, set the reason
      to be 'Trace'.

9ccb970f23 Make lldb::endian::InlHostByteOrder() private.
Summary:
Since this is within the lldb namespace, the compiler tries to
export a symbol for it. Unfortunately, since it is inlined, the
symbol is hidden and this results in a mess of warnings when
building on OS X with cmake.

Moving it to the lldb_private namespace eliminates that problem.

b36f917854 Remove old local-only linux debugging code
Summary:
Currently, the local-only path fails about 50% of the tests, which means that: a) nobody is using
it; and b) the remote debugging path is much more stable. This commit removes the local-only
linux debugging code (ProcessLinux) and makes remote-loopback the only way to debug local
applications (the same architecture as OSX). The ProcessPOSIX code is moved to the FreeBSD
directory, which is now the only user of this class. Hopefully, FreeBSD will soon move to the new
architecture as well and then this code can be removed completely.

Test Plan: Test suite passes via remote stub.
