it to interpret a "this" variable that was merely
a pointer -- that is, not a class pointer -- as
meaning that the current context was inside a C++
method. This bug would prevent expressions from
evaluating correctly in regular C code if there
was a pointer variable named "this" in scope.

they may be in sensitive areas and we set breakpoints on the thread creation routines
if we are running expressions, so the threads should quickly get to a safe spot.

provision for specifying a working directory with the name LaunchWithCWD in our
target language (Python) for now. This fixes the test suite failures due to the
overloading.

takes separate file handles for stdin, stdout, and stder and also allows for
the working directory to be specified.
Added support to "process launch" to a new option: --working-dir=PATH. We
can now set the working directory. If this is not set, it defaults to that
of the process that has LLDB loaded. Added the working directory to the
host LaunchInNewTerminal function to allows the current working directory
to be set in processes that are spawned in their own terminal. Also hooked this
up to the lldb_private::Process and all mac plug-ins. The linux plug-in had its
API changed, but nothing is making use of it yet. Modfied "debugserver" and
"darwin-debug" to also handle the current working directory options and modified
the code in LLDB that spawns these tools to pass the info along.
Fixed ProcessGDBRemote to properly pass along all file handles for stdin, stdout
and stderr.
After clearing the default values for the stdin/out/err file handles for
process to be NULL, we had a crasher in UserSettingsController::UpdateStringVariable
which is now fixed. Also fixed the setting of boolean values to be able to
be set as "true", "yes", "on", "1" for true (case insensitive) and "false", "no",
"off", or "0" for false.
Fixed debugserver to properly handle files for STDIN, STDOUT and STDERR that are not
already opened. Previous to this fix debugserver would only correctly open and dupe
file handles for the slave side of a pseudo terminal. It now correctly handles
getting STDIN for the inferior from a file, and spitting STDOUT and STDERR out to
files. Also made sure the file handles were correctly opened with the NOCTTY flag
for terminals.

checking the validity of the shared pointer prior to using it.
Fixed the GDB remote plug-in to once again watch for a reply from the "k"
packet, and fixed the logic to make sure the thread requesting the kill
and the async thread play nice (and very quickly) by synchronizing the
packet sending and reply. I also tweaked some of the shut down packet
("k" kill, "D" detach, and the halt packet) to make sure they do the right
thing.
Fixed "StateType Process::WaitForProcessStopPrivate (...)" to correctly pass
the timeout along to WaitForStateChangedEventsPrivate() and made the function
behave correctly with respect to timing out.
Added separate STDIN, STDOUT, and STDERR support to debugserver. Also added
the start of being able to set the working directory for the inferior process.

threads that we spawn let us know when they are going away and that we
don't timeout waiting for a message from threads that have gone away.
We also now don't expect the "k" packet (kill) to send a response. This
greatly speeds up debugger shutdown performance. The test suite now runs
quite a bit faster.
Added a fix to the variable display code that fixes the display of
base classes. We were assuming the virtual or normal base class offsets
were being given in bit sizes, but they were being given as character
sizes, so we needed to multiply the offset by 8. This wasn't affecting
the expression parser, but it was affecting the correct display of C++
class base classes and all of their children.

we are requesting a single thread to run. May seem like a silly thing to do, but the kernel
on MacOS X will inject new threads into a program willy-nilly, and I would like to keep them
from running if I can.

to be fed 4 callbacks: read/write memory, and read/write registers. After this,
you can tell the object to read an instruction. This will cause the class to read
the PC, and read and instruction. Then you can emulate the instruction by calling
EvaluateInstruction. This will cause the class to figure out exactly what an opcode
does, and call the read/write mem/regs functions with actual values which allows one
to emulate an instruction without running a process, or it allows one to watch the
context information (the memory write is a pushing register 3 onto the stack at offset
12) so it can be used for generating call frame information. This way, in the future,
we will have one class that can be used to emulate instructions and generate our
unwind info from assembly.

select frame #3, you can then do a step out and be able to go directly to the
frame above frame #3!
Added StepOverUntil and StepOutOfFrame to the SBThread API to allow more powerful
stepping.
