Jonas Devlieghere 15eacd741f [Reproducers] Change how reproducers are initialized.
This patch changes the way the reproducer is initialized. Rather than
making changes at run time we now do everything at initialization time.
To make this happen we had to introduce initializer options and their SB
variant. This allows us to tell the initializer that we're running in
reproducer capture/replay mode.

Because of this change we also had to alter our testing strategy. We
cannot reinitialize LLDB when using the dotest infrastructure. Instead
we use lit and invoke two instances of the driver.

Another consequence is that we can no longer enable capture or replay
through commands. This was bound to go away form the beginning, but I
had something in mind where you could enable/disable specific providers.
However this seems like it adds very little value right now so the
corresponding commands were removed.

Finally this change also means you now have to control this through the
driver, for which I replaced --reproducer with --capture and --replay to
differentiate between the two modes.

Jonas Devlieghere 2ad6e0a696 Move pretty stack trace printer into driver.
We used to have a pretty stack trace printer in SystemInitializerCommon.
This was disabled on Apple because we didn't want the library to be
setting signal handlers, as this was causing issues when loaded into
Xcode. However, I think it's useful to have this for the LLDB driver, so
I moved it up to use the PrettyStackTraceProgram in the driver's main.

Pavel Labath fa3fa5b90e Move ObjectFile initialization out of SystemInitializerCommon
Summary:
For lldb-server, it is sufficient to parse only the native object file
format for its target OS (no other file can be loaded into a running
process). This moves the object file initialization code into specific
initializer classes: lldb-test and liblldb get all object files;
lldb-server gets only one of them. For this to work, I've needed to
create a special SystemInitializer for use in lldb-server, instead of it
calling directly into the common one.

This reduces the size of lldb-server by about 2%, which is not
earth-shattering, but it's an easy win, and it helps.

Kate Stone 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.

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.

Robert Flack f196c93172 Add Debugger::InitializeForLLGS to allow ref counted LLGS initialization.
After http://reviews.llvm.org/D8133 landed as r231550 process launch on remote platform stopped working.

This adds Debugger::InitializeForLLGS and tracks whether one or both of Initialize and InitializeForLLGS have been called, calling only the corresponding lldb_private::Terminate* methods as necessary. Since lldb_private::Terminate calls lldb_private::TerminateForLLGS, the latter method may be called twice if Initialize was called for both however the terminate methods ensure they are only called once after being initialized.

This still maintains the reduced binary size, though it does now technically link in lldb_private::Terminate on lldb-server even though this should never be called.

This should resolve the issue raised in http://reviews.llvm.org/D8133 where Debugger::Terminate assumed that there were 0 references to debugger and terminated early.

Robert Flack ab3269d275 Reduce the number of components initialized by lldb-server to reduce static binary size.
Separate out the necessary component initialization for lldb-server such that the linker can greatly reduce the binary size. With this patch the size of lldb-server on my 64 bit linux release build drops from 46MB to 26MB.

Tamas Berghammer c2c3d7185d Merge lldb-platform and lldb-gdbserver into a single binary
This commit merges lldb-platform and lldb-gdbserver into a single binary
of the same size as each of the previous individual binaries. Execution
mode is controlled by the first argument being either platform or
gdbserver.
