Greg Clayton 3e32ad65fb Allow clients to control the exact path that is used to launch processes by adding new calls to SBLaunchInfo.
The new calls are:

SBFileSpec
SBLaunchInfo::GetExecutableFile ();

void
SBLaunchInfo::SetExecutableFile (SBFileSpec exe_file, bool add_as_first_arg);

Todd Fiala 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).

Ed Maste d010f9a8a5 If CMake finds a python interpreter, use it
The FreeBSD package building cluster installs e.g. 'python2.7', but no
plain 'python' to avoid version-related issues.

CMake's FindPythonInterp locates an interpreter with such a name and
provides it in the PYTHON_EXECUTABLE variable.  Use that if it's set,
falling back to the original '/usr/bin/env python' otherwise.

This is a missing part of LLDB commit r207122.
Patch by Brooks Davis in FreeBSD ports commit r353052

Todd Fiala f9c3c9fe44 gdbremote testing: added regex support to match packets and propagate/test against previously stored matches.
Added a test validating that $qC after an inferior launch via $A
returns a thread id that an immediately followig $? reports for the
active thread. This is currently skipped on debugserver (the thread
ids don't match) and isn't yet implemented in TOT for llgs.

Jason Molenda 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).

Todd Fiala 6764c00687 Refactored gdb remote protocol testing sequence handling.
Pushed gdbremote protocol sequence expectations into a separate
class and defer matching of llgs/debugserver output to the
sequence entry.  Pre-step to adding regex matching and
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
and test expectations matching.

Todd Fiala 71afe0b1d5 Make lldb-gdbserver configure/(g)make build parity with cmake.
This now builds lldb-gdbserver on all Linux and FreeBSD architectures
rather than being locked to x86_64 architectures only.

Please note lldb-gdbserver is not yet functional, this just enables
the non-x86_64 Linux/FreeBSD build using the configure/make build
system.

Todd Fiala a41d48cac8 Added two new test types: @debugserver_test and @llgs_test.
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).

Todd Fiala 98118c38a3 Prevent TestLldbGdbServer shutdown cleanup failures from failing the test.
Adds try/except blocks around clean-up code. Prevents a race between gdb
remote kill command reception by llgs (which leads llgs to shut down)
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.

On Linux x86_64 (Ubuntu 12.04) I am sometimes getting a full path

Greg Clayton 0c4129f2f7 Make sure that the CommandInterpreter::m_command_io_handler_sp gets reset when we quit.
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.

This makes sure that your LLDB command interpreter history is saved each time you quit command line LLDB.
