Jason Molenda 07c446baf4 Fix one remaining mach port number/globally unique thread ID mixup which prevented queue names
from being fetched correctly.  <rdar://problem/13290877>

Jason Molenda 1c73911d42 Change debugserver from using the mach port number (in debugserver's
own port namepsace) as the thread identifier to using the system-wide
globally unique thread id as the thread identifier number.

MachThread.cpp keeps both the unique id and the mach port number
for each thread.  All layers outside MachThread class use the unique
id with three exceptions: (1) Mach exceptions come in with the port
number (thread_port) which needs to be translated, (2) any calls to
low-level thread_get_state/thread_set_state/thread_suspend etc need
to use the mach port number, (3) MachThreadList::UpdateThreadList 
which creates the MachThread objects gets the unique id and passes
it to the MachThread ctor as an argument.

In general, any time nub_thread_t is used, it is now referring to a
unique thread id.  Any time a thread_t is used, it is now referring
to a mach port number.  There was some interchangability of these 
types previously.  nub_thread_t has also been changed to a 64-bit
type which necessitated some printf specification string changes.

I haven't been able to test these changes extensively yet but want
to checkpoint the work.  The scenarios I've been testing are all
working correctly so while there may be some corner cases I haven't
hit yet, I think it is substantially correct.

Johnny Chen 6463720505 Add the capability to display the number of supported hardware watchpoints to the "watchpoint list" command.
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.

Greg Clayton 26783fea37 Added logging for threads that are spawned while we stop. We log their
existence if the "thread" log bit is enabled right before we resume.

Greg Clayton e2d4f0d7ce Took the timeout for a ClangUserExpression down from a 10 second timeout to
500 ms.

Make MachThreadList more threadsafe.

Added code to make sure the thread register state was properly flushed for x86_64.

Fixed an missing return code for the current thread in the new thread suffix code.

Improved debugserver logging.

Greg Clayton 3af9ea56d3 Fixed Process::Halt() as it was broken for "process halt" after recent changes
to the DoHalt down in ProcessGDBRemote. I also moved the functionality that
was in ProcessGDBRemote::DoHalt up into Process::Halt so not every class has
to implement a tricky halt/resume on the internal state thread. The 
functionality is the same as it was before with two changes:
- when we eat the event we now just reuse the event we consume when the private
  state thread is paused and set the interrupted bool on the event if needed
- we also properly update the Process::m_public_state with the state of the
  event we consume.
  
Prior to this, if you issued a "process halt" it would eat the event, not 
update the process state, and then produce a new event with the interrupted
bit set and send it. Anyone listening to the event would get the stopped event
with a process that whose state was set to "running".

Fixed debugserver to not have to be spawned with the architecture of the
inferior process. This worked fine for launching processes, but when attaching
to processes by name or pid without a file in lldb, it would fail.

Now debugserver can support multiple architectures for a native debug session
on the current host. This currently means i386 and x86_64 are supported in
the same binary and a x86_64 debugserver can attach to a i386 executable.
This change involved a lot of changes to make sure we dynamically detect the
correct registers for the inferior process.

Greg Clayton 58d1c9a44f Still trying to get detach to work with debugserver. Got a bit closer,
but something is still killing our inferior.

Fixed an issue with darwin-debug where it wasn't passing all needed arguments
to the inferior.

Fixed a race condition with the attach to named process code.
