Python defines _XOPEN_SOURCE and _POSIX_C_SOURCE unconditionally. On Linux,
this is problematic as glibc's features.h defines these values if _GNU_SOURCE is
defined to the value that is currently implemented. Python defines it to the
versions that it requires, which may be different. Undefine the macros on Linux
(technically, this should be safe to do globally) before including the python
headers.

$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).

The FreeBSD package building cluster installs e.g. 'python2.7', but no

CMake's FindPythonInterp locates an interpreter with such a name and

falling back to the original '/usr/bin/env python' otherwise.
This is a missing part of LLDB commit r207122.

Added a test validating that $qC after an inferior launch via $A

active thread. This is currently skipped on debugserver (the thread
ids don't match) and isn't yet implemented in TOT for llgs.

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).

Pushed gdbremote protocol sequence expectations into a separate

grouped content collecting.
No longer require anything before the read/send packet
portion of slurped-up log lines used for setting up
gdb remote test sequences. Several packet logging options
produce a wide range of content before the read/send packet.
Added helpers to TestLldbGdbServer to clean up test setup

TestLldbGdbServer now supports both lldb-gdbserver (llgs) and
debugserver tests. Similar to the dsym/dwarf tests, they allow
running the same underlying gdb remote protocol tests against
lldb-gdbserver and debugserver. This will help make sure the
protocol-level tests for lldb-gdbserver faithfully represent
what debugserver does on OS X.
Switched back gdb remote protocol test logging to warning
and above (accidentally submitted it at debug level in a
recent commit).

Adds try/except blocks around clean-up code. Prevents a race between gdb

and the pexpect server kill (which can fail if the kill command handling
completes first). Warnings are emitted on the logger for any clean-up
code that fails.

Currently if you run _any_ python, python has the "lldb.debugger" global variable and it has a strong reference to a lldb_private::Debugger since it is a lldb::SBDebugger object with a shared pointer.

lldbgdbserverutils.py has a new expect_lldb_gdbserver_replay() method
that plays back gdb remote send/receive packets. These packets are the
log lines that come from running the 'log enable gdb-remote packets',
either from the lldb-gdbserver side or the lldb side. There's a flag
to flip which side is the send (lldb-gdbserver input or lldb-gdbserver
output).
This first checkin tests the initial gdbremote handshake, the ability
to turn on the no-ack mode communication style, thread suffix support,
and list threads in stop reply support. The last two are marked xfail
as top of tree does not yet support these.

This updates the target_link_libraries invocation when building with CMake
2.8.12 or newer. The newer version of CMake warns when keyword and plain
signatures are used for target_link_libraries. This addresses that difference
while maintaining compatibility with the older releases by defining a macro for
the keyword that is defined based on the current version of CMake.

Our build is still getting this test to fail with the presence of const in
'(Foo &const) y = 0x' and '(Foo &&const) z = 0x'. This change simply changes
the match substrings to ignore the portion after the final '&' and before the
closing ')'. This should cover the presence (or absence) of the const qualifier.

Enable data formatters to see-through pointers/references to typedefs
For instance, if Foo is a typedef to Bar, and there is a formatter for any/all of Bar*, Bar&, Bar&&, then Foo*, Foo&, and Foo&& should pick these up if Foo-specific formatters don't exist
llvm-svn: 205939
Set the correct FormatManager revision before starting to figure out the new formatters
This can avoid entering some corner cases where as part of figuring out formatters we try to figure out dynamic types, and in turn that causes us to go back in trying to fetch new formatters - it is not only a futile exercise, it's also prone to endless recursion
This would only cause a behavior change if getting this chain started would eventually cause something to run and alter the formatters, a very unlikely if at all possible sequence of events

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
