Fixed an issue where if we call "Process::Destroy()" and the process is running, if we try to stop it and get "exited" back as the stop reason, we will still deliver the exited event.

Add an lldb command line option to specify a core file: --core/-c.
For consistency, change the "target create" command to also use --core.

Convert from calling Halt in the lldb Driver.cpp's input reader's sigint handler to sending this AsyncInterrupt so it can be handled in the
event loop.
If you are attaching and get an async interrupt, abort the attach attempt.
Also remember to destroy the process if get interrupted while attaching.
Getting this to work also required handing the eBroadcastBitInterrupt in a few more places in Process WaitForEvent & friends.

calling functions. This is necessary on Mac OS X, since bad things can happen if you set
the registers of a thread that's sitting in a kernel trap.

Allow debugserver to match process names that are longer than MAXCOMLEN (16) characters. We do this by digging up argv[0] from another sysctl if the process name supplied is longer than 16 characters.

Designate MachThreadList as a transaction coordinator when doing Enable/DisableHardwareWatchpoint on the list of threads.
In case the operation (iterating on the threads and doing enable/disable) fails in the middle, we rollback the already
enabled/disabled threads to their checkpointed states. When all the threads succeed in enable/disable, we ask each thread
to finsih the transaction and commit the change of the debug state.

Add default Process::GetWatchpointSupportInfo() impl which returns an error of "not supported".
Add "qWatchpointSupportInfo" packet to the gdb communication layer to support this, and modify TestWatchpointCommands.py to test it.

Switch over to the "*-apple-macosx" for desktop and "*-apple-ios" for iOS triples.
Also make the selection process for auto selecting platforms based off of an arch much better.

should be MasterPlans that want to stay on the plan stack. So make all plans NOT
MasterPlans by default and then have the SB API's and the CommandObjectThread step
commands set this explicitly.
Also added a "clean up" phase to the Thread::ShouldStop so that if plans get stranded
on the stack, we can remove them. This is done by adding an IsPlanStale method to the
thread plans, and if the plan can know that it is no longer relevant, it returns true,
and the plan and its sub-plans will get discarded.

Just call SBDebugger::SetTerminalWidth on the driver's SBDebugger, which does the same job, but no locks.
Also add the value checking to SetTerminalWidth you get with SetInternalVariable(..., "term-width", ...).

QListThreadsInStopReply
This GDB remote query command can enable added a "threads" key/value pair to all stop reply packets so that we always get a list of all threads in each stop reply packet. It increases performance if enabled (the reply to the "QListThreadsInStopReply" is "OK") by saving us from sending to command/reply pairs (the "qfThreadInfo" and "qsThreadInfo" packets), and also helps us keep the current process state up to date.

We do this by delegating to two available Watchpoint Register Pairs (wvr, wcr). With
each pair handling the 4 bytes of (uint64_t)variable.

that the inferior cannot execute past the watchpoint-triggering instruction.
The solution is disable the watchpoint before resuming the inferior and make it hardware single step;
when the inferior stops again due to single step, re-enable the watchpoint and disable the single step
to make the inferior able to continue again without obstacle.

However, the debugserver cannot get past the instruction which triggered the watchpoint.
So a workaround is in place for the time being which disables the triggered watchpoint
before resuming.
Lots of commented out printf's remain in the source which needs to be cleaned up.

On darwin, if child process of process being debugged dies due to mach exception, the debugged process will die.
debugserver now only handles the mach exceptions for the task being debugged.

Added a new makefile target to help us with Apple builds where the installhdrs
will copy the headers for the shared library. Prior to this fix, the install
headers directory would contain the unix style paths to all public header
files ("#include lldb/API/SBDefines.h") instead of the fixed up framework
header paths ("#include <LLDB/SBDefines.h>").

Fixed STDERR to not be opened as readable. Also cleaned up some of the code that implemented the file actions as some of the code was using the wrong variables, they now use the right ones (in for stdin, out for stdout, err for stderr).

"desktop" - build all binaries with XPC
"desktop_no_xcp" - build all binaries with none of the XPC binaries
"ios" - build all binaries with special iOS install settings.
Bumped the Xcode project build version for lldb-118 and debugserver-169.

Added the ability to override command line commands. In some cases GUI interfaces
might want to intercept commands like "quit" or "process launch" (which might cause
the process to re-run). They can now do so by overriding/intercepting commands
by using functions added to SBCommandInterpreter using a callback function. If the
callback function returns true, the command is assumed to be handled. If false
is returned the command should be evaluated normally.
Adopted this up in the Driver.cpp for intercepting the "quit" command.
