fbe0b9abf9 ReExported symbols can point to a library that doesn't actually
contain the symbol, but just reexports wholesale from another
library.  Handle this case.

ff6131a958 Add support for gdb remote $X stop notification.
debugserver now returns $X09 as the immediate response to
a $k kill process request rather than $W09.

ProcessGDBRemote now properly handles X as indication of
a process exit state.

The @debugserver_test and @lldb_test for $k now properly expects
an X notification (signal-caused exit) after killing a just-attached
inferior that was still in the stopped state.

e24614f74e lldb: gdb remote support always falls back to $qC when no $qProcessInfo.
See thread here:
http://lists.cs.uiuc.edu/pipermail/lldb-dev/2014-May/003992.html

This is meant to address case 3 that I recently broke with an earlier
change to rectify usage of the $qC message for thread ids, specifically:

3. TOT lldb <=> gdbserver (without $qProcessInfo support and not Apple/iOS).

b4892cd266 Add a new SBThread::SafeToCallFunctions API; this calls over to
the SystemRuntime to check if a thread will have any problems 
performing an inferior function call so the driver can skip
making that function call on that thread.  Often the function
call can be executed on another thread instead.

2fc43a3821 Args::StringToGenericRegister will now accept "lr" as
another way to indicate that this register is a generic
Return Address register (in addition to "ra") - this is
used primarily by OperatingSystem plugins.

Correctly annotate the UnwindPlan created by EmulateInstructionARM64
to indicate that it was not sourced from a compiler and it
is valid at every instruction.

9f72b3a1ce Modify debugserver to follow gdb remote $qC protocol definition.
$qC from debugserver now returns the current thread's thread-id (and, like $?, will set a current thread if one is not already selected).  Previously it was returning the current process id.

lldb will now query $qProcessInfo to retrieve the process id.  The process id is now cached lazily and reset like other cached values.  Retrieval of the process id will fall back to the old $qC method for vendor==Apple and os==iOS if the qProcessInfo retrieval fails.

Added a gdb remote protocol-level test to verify that $qProcessInfo reports a valid process id after launching a process, while the process is in the initial stopped state.  Verifies the given process id is a currently valid process on host OSes for which we know how to check (MacOSX, Linux, {Free/Net}BSD).  Ignores the live process check for OSes where we don't know how to do this.  (I saw no portable way to do this in stock Python without pulling in other libs).

6076bf4edb Change ProcessGDBRemote::DoReadMemory to use the x packet to read
data if it is available.

Change ProcessGDBRemote's maximum read/write packet size from a
fixed 512 byte value to asking the remote gdb stub what its maximum
is, using up to 128kbyte sizes if that's allowed, and falling back
to 512 if the remote gdb stub doesn't advertise a max packet size.

Add a new "process plugin packet xfer-size" command that can be used
to override the maximum packet size (although not exceeding any packet
size maximum published by the remote gdb stub).

d20deac32d Xcode 5 crashes if lldb stops at breakpoint if long c++ template lists are present.
This fix reduces the stack size of SymbolFileDWARF::ParseType(). It seems that clang is not very good at sharing locations on the stack with local variables in large functions that have many blocks and each variable gets unique locations. The reduction in size was done by:
1 - removing some large locals that were default constructed by not used
2 - Placing some larger local variables into std::unique_ptr<> to make them on the heap
3 - removing local variables there were large and being populated but not being used
4 - reducing the size of some typedefs to llvm::SmallVector<T, N> so that N wasn’t excessively large
