Saleem Abdulrasool bb19a13c0b second pass over removal of Mutex and Condition

Saleem Abdulrasool 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.

Jim Ingham 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.

Sean Callanan 3e7e915dca Added support for the "--repl" argument to LLDB.
This makes LLDB launch and create a REPL, specifying no target so that the REPL
can create one for itself.  Also added the "--repl-language" option, which
specifies the language to use.  Plumbed the relevant arguments and errors
through the REPL creation mechanism.

Zachary Turner 1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

Zachary Turner e6e2bb3842 Rework LLDB system initialization.
In an effort to reduce binary size for components not wishing to
link against all of LLDB, as well as a parallel effort to reduce
link dependencies on Python, this patch splits out the notion of
LLDB initialization into "full" and "common" initialization.

All code related to initializing the full LLDB suite lives directly
in API now.  Previously it was only referenced from API, but because
it was defined in lldbCore, it would get implicitly linked against
by everything including lldb-server, causing a considerable
increase in binary size.

By moving this to the API layer, it also creates a better layering
for the ongoing effort to make the embedded interpreter replacable
with one from a different language (or even be completely removeable).

One semantic change necessary to get this all working was to remove
the notion of a shared debugger refcount.  The debugger is either
initialized or uninitialized now, and calling Initialize() multiple
times will simply have no effect, while the first Terminate() will
now shut it down no matter how many times Initialize() was called.
This behaves nicely with all of our supported usage patterns though,
and allows us to fix a number of nasty hacks from before.

Zachary Turner 3a00691f3d Move LLDB initialization/shutdown to Initialization.
This creates a new top-level folder called Initialization which
is intended to hold code specific to LLDB system initialization.
Currently this holds the Initialize() and Terminate() functions,
as well as the fatal error handler.

This provides a means to break the massive dependency cycle which
is caused by the fact that Debugger depends on Initialize and
Terminate which then depends on the entire LLDB project.  With
this structure, it will be possible for applications to invoke
lldb_private::Initialize() directly, and have that invoke
Debugger::Initialize.

Greg Clayton bf702ceed1 Fixed "SBTarget SBDebugger::CreateTarget (const char *filename)" to use the same semantics as other SBDebugger::CreateTarget() functions.
The issues were:
- If you called this function with any arch other than the default target architecture, creating the target would fail because the Target::GetDefaultArchitecture() would not match the single architecture in the file specified. This caused running the test suite remotely with lldb-platform to fail many many tests due to the bad target.
- It would specify the currently selected platform which might not work for the specified platform

All other SBDebugger::CreateTarget calls do not assume an architecture or platform and if they aren't specified, they don't auto select the wrong one for you.

With this fix, SBTarget SBDebugger::CreateTarget (const char *filename) now behaves like the other SBDebugger::CreateTarget() variants.

Jim Ingham ffc9f1de34 This adds a "batch mode" to lldb kinda like the gdb batch mode. It will quit the debugger
after all the commands have been executed except if one of the commands was an execution control
command that stopped because of a signal or exception.

Also adds a variant of SBCommandInterpreter::HandleCommand that takes an SBExecutionContext.  That
way you can run an lldb command targeted at a particular target, thread or process w/o having to 
select same before running the command.

Also exposes CommandInterpreter::HandleCommandsFromFile to the SBCommandInterpreter API, since that
seemed generally useful.

Jim Ingham 26c7bf9312 Rework the way we pass "run multiple command" options to the various API's that
do that (RunCommandInterpreter, HandleCommands, HandleCommandsFromFile) to gather
the options into an options class.  Also expose that to the SB API's.

Change the way the "-o" options to the lldb driver are processed so:
1) They are run synchronously - didn't really make any sense to run the asynchronously.
2) The stop on error
3) "quit" in one of the -o commands will not quit lldb - not the command interpreter
that was running the -o commands.

I added an entry to the run options to stop-on-crash, but I haven't implemented that yet.

Greg Clayton 615eb7e609 Test suite runs better again after recent fixes that would select a platform if a "file a.out" auto selected a different platform than the selected one.
Changes include:
- fix it so you can select the "host" platform using "platform select host"
- change all callbacks that create platforms to returns shared pointers
- fix TestImageListMultiArchitecture.py to restore the "host" platform by running "platform select host"
- Add a new "PlatformSP Platform::Find(const ConstString &name)" method to get a cached platform
- cache platforms that are created and re-use them instead of always creating a new one

Zachary Turner 58a559c07e Update LLDB to use LLVM's DynamicLibrary.
LLDB had implemented its own DynamicLibrary class for plugin
support.  LLVM has an equivalent mechanism, so this patch deletes
the duplicated code in LLDB and updates LLDB to reference the
mechanism provided by LLVM.

Greg Clayton 44d937820b Merging the iohandler branch back into main.
The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)

We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

Greg Clayton 5fb8f79738 Fixed internal code to not link against and code from "lldb/API/*".
lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used.

Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number. 

Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing. This forces all symbols to not be exported, and also quiets the linker warnings.

Greg Clayton fbb7634934 Expose SBPlatform through the public API.
Example code:

remote_platform = lldb.SBPlatform("remote-macosx"); 
remote_platform.SetWorkingDirectory("/private/tmp")
debugger.SetSelectedPlatform(remote_platform)

connect_options = lldb.SBPlatformConnectOptions("connect://localhost:1111"); 
err = remote_platform.ConnectRemote(connect_options)
if err.Success():
    print >> result, 'Connected to remote platform:'
    print >> result, 'hostname: %s' % (remote_platform.GetHostname())
    src = lldb.SBFileSpec("/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework", False)
    dst = lldb.SBFileSpec()
    # copy src to platform working directory since "dst" is empty
    err = remote_platform.Install(src, dst);
    if err.Success():
        print >> result, '%s installed successfully' % (src)
    else:
        print >> result, 'error: failed to install "%s": %s' % (src, err)


Implemented many calls needed in lldb-platform to be able to install a directory that contains symlinks, file and directories.

The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform.

The API in SBPlatform is subject to change and will be getting many new functions.
