Summary:
this also gets rid of a compiler warning in release builds by using a dynamically allocated
buffer. Therefore, a size assertion is not necessary (and probably should have been an error in
the first place).

When launching argdumper, there are a few problems with the
current logic. First, on Windows, the file is called
argdumper.exe, not argdumper. Second, Windows paths have
backslashes in them, and JSON treats <backslash><char> as an
escape sequence. To fix the second problem, on Windows we
convert backslashes to forward slashes, since backslash isn't
a valid filename character anyway this shouldn't be a problem.

llvm::StringRef doesn't make a copy of a string, it just holds a
reference. When special_directions_stream went out of scope,
special_directions was holding on to a stale pointer.
Moving special_directions_stream into a higher scope to keep
special_directions pointing to a valid string.

target.error-path (and output-path) were getting resolved on the
local file system, which doesn't make any sense for remote targets
So this patch prevents file paths from being resolved on the host
system.

CopyContext is necessary to safely get the XState, but LLDB doesn't currently
use the XState. CopyContext is available as of Windows 7 SP1, so it can't be
used on Vista. Furthermore, it requires the Windows 8 SDK it compile,
making the baseline for compiling and running LLDB higher than necessary.

This commit merges lldb-platform and lldb-gdbserver into a single binary
of the same size as each of the previous individual binaries. Execution

Previously we would create the extension module as a post-build
step of creating liblldb. As part of this process, we created
symlinks and did other stuff.
This had several longstanding issues related to target
dependencies, such as not re-creating the symlink if liblldb.dll
failed to link, or if the build was Ctrl+C'ed from.
Then, the script that creates the symlinks began to grow to
include other things, such as argdumper, and it would try to
create symlinks before it had finished building the targets it
needed to symlink to.
This patches addresses all of these problems by creating an
explicit target for the script to run, and making it have a
dependency on all the targets it needs to create symlinks from/to.

Summary:
Currently we have some settings which treat "\ " on settings set commands specially. E.g., it is
a valid way of specifying an argument of " " to a target. However, this fails if "\ " is the last
argument as CommandObjectSettingsSet strips trailing whitespace. This resulted in a surprising
argument of "\" to the target.
This patch disables the training whitespace removal at a global
level. Instead, for each argument type we locally determine whether whitespace stripping makes
sense. Currently, I strip whitespace for all simple object type except of regex and
format-string, with the rationale that these two object types do their own complex parsing and we
want to interfere with them as least as possible. Specifically, stripping the whitespace of a
regex "\ " will result in a (surprising?) error "trailing backslash". Furthermore, the default
value of dissasembly-format setting already contains a trailing space and there is no way for the
user to type this in manually if we strip whitespace.

This patch adds -exec-arguments command for lldb-mi. -exec-arguments command allows to specify arguments for executable file in MI mode. Also it contains tests for that command.

signed and unsigned types in comparisons.
For the text offset, use the addr_t type that is used elsewhere to get
these kinds of offsets, and which it is being compared against. This
seems to make things more consistent.
For the other, the numbers are clearly small and uninteresting, so just
cast them to the most boring 'int' type.

On PowerPC, and maybe some other architectures, 'char' is unsigned. Comparing
an unsigned char with a signed int (-1) is always false. To fix this, down-cast
EOF to a char.

There was a test in the test suite that was triggering the backtrace logging output that requested that the client pass an execution context. Sometimes we need the process for Objective C types because our static notion of the type might not align with the reality when being run in a live runtime.
Switched from an "ExecutionContext *" to an "ExecutionContextScope *" for greater ease of use.

Rules for returning "const char *" from functions in the public lldb::SB* API are that you must constify the string using "ConstString(cstr).GetCString()" and return that. This puts the string into a string pool that never goes away. This is only when there is nothing that can hold onto the string. It is OK to specify that a string value lives as long as its SB class counterpart, but this should be made clear in the API if this is done. Many classes already constify their strings (symbol mangled and demangled names, variable names, type names, etc), so be sure to verify you string isn't already constified before you re-constify it. It won't do any harm to re-constify it, it will just cause you a little performance by having to rehash the string.

SBProcess uses 2 mutexex; RunLock and APILock. Apart from 2 places, RunLock
is locked before API lock. I have fixed the 2 places where order was different.
I observed a deadlock due to this different order in lldb-mi once. Although
lldb-mi command and event thread dont run at the same time now. So it can not deadlock
there but can still be problem for some other clients.
