symbols correctly. There were a couple of pieces to this.
1) When a breakpoint location finds itself pointing to an Indirect symbol, when the site for it is created
it needs to resolve the symbol and actually set the site at its target.
2) Not all breakpoints want to do this (i.e. a straight address breakpoint should always set itself on the
specified address, so somem machinery was needed to specify that.
3) I added some info to the break list output for indirect symbols so you could see what was happening.
Also I made it clear when we re-route through re-exported symbols.
4) I moved ResolveIndirectFunction from ProcessPosix to Process since it works the exact same way on Mac OS X
and the other posix systems. If we find a platform that doesn't do it this way, they can override the
call in Process.
5) Fixed one bug in RunThreadPlan, if you were trying to run a thread plan after a "running" event had
been broadcast, the event coalescing would cause you to miss the ThreadPlan running event. So I added
a way to override the coalescing.
6) Made DynamicLoaderMacOSXDYLD::GetStepThroughTrampolinePlan handle Indirect & Re-exported symbols.

Just pass a Target* into ObjectFileELF::GetImageInfoAddress so that
it can do the extra dereference necessary on MIPS, instead of passing
a flag back to the caller.

MIPS's .dyanamic section is read-only. Instead of using DT_DEBUG for
the pointer to dyld information it uses a separate tag DT_MIPS_RLD_MAP
which points to storage in the read-write .rld_map section, which in
turn points to the dyld information.

Instead of directly manipulating the thread list in Launch and Attach,
just rely on RefreshStateAfterStop to populate the initial list.

On Linux there is no separate notion of a process (vs. a thread) for
ptrace(); each thread needs to be individually detached. On FreeBSD
we have a separate process context, and we detach just it.

Summary:
This merge brings in the improved 'platform' command that knows how to
interface with remote machines; that is, query OS/kernel information, push
and pull files, run shell commands, etc... and implementation for the new
communication packets that back that interface, at least on Darwin based
operating systems via the POSIXPlatform class. Linux support is coming soon.
Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
X Mountain Lion.
Additional improvements (not in the source SVN branch 'lldb-platform-work'):
- cmake build scripts for lldb-platform
- cleanup test suite
- documentation stub for qPlatform_RunCommand
- use log class instead of printf() directly
- reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
- add new logging category 'platform'

Created new LinuxThread class inherited from POSIXThread and removed linux / freebsd ifdefs
Removed several un-needed set thread name calls

- process in 'unloaded' state was (incorrectly) considered to be alive by POSIX plugin
- above caused a regression in TestProcessLaunch cases

- All Linux logging channels now use a single global instance of lldb_private::Log, to handle the case of logging during process tear down.
- Also removed a single use of LogSP in FreeBSD and fixed a typo in a comment while reading through ProcessKDPLog.

Patch by Matt Kopec!

The attached patch fixes a problem with performing an attach from the SBTarget API on Linux (and other systems that use ProcessPOSIX).
When Process::Attach was called from SBTarget, it resulted in a call to a form of the DoAttachWithID function that wasn't implemented in ProcessPOSIX, and so it fell back to the default implementation (which just returns an error). It didn't seem necessary to use the attach_info parameter for this case, so I just implemented it as a call to the simpler version of the function.
In debugging this problem, I also found that SBTarget wasn't checking the return value from the Attach call, causing it to hang when the attach fails.

Hello everyone,
please find the attached patch for TOT and lldb-platform-work branch, which provides the following changes:
- fixed a crash in the ProcessPOSIX constructor when an executable module object is not yet created.
- added support for the multi instanciated FreeBSD platform objects (the local host and remote as example).
- enabled the remote gdb plugin on FreeBSD.
