Summary:
Since this is within the lldb namespace, the compiler tries to
export a symbol for it. Unfortunately, since it is inlined, the
symbol is hidden and this results in a mess of warnings when
building on OS X with cmake.
Moving it to the lldb_private namespace eliminates that problem.

when they introduced android testsuite regressions. Pavel has run the
testsuite against the updated patch and it completes cleanly now.
The original commit message:
Fixing a subtle issue on Mac OS X systems with dSYMs (possibly
introduced by r235737 but I didn't look into it too closely).
A dSYM can have a per-UUID plist in it which tells lldb where
to find an executable binary for the dSYM (DBGSymbolRichExecutable)
- other information can be included in this plist, like how to
remap the source file paths from their build pathnames to their
long-term storage pathnames.
This per-UUID plist is a unusual; it is used probably exclusively
inside apple with our build system. It is not created by default
in normal dSYMs.
The problem was like this:
1. lldb wants to find an executable, given only a UUID
(this happens when lldb is doing cross-host debugging
and doesn't have a copy of the target system's binaries)
2. It eventually calls LocateMacOSXFilesUsingDebugSymbols
which does a spotlight search for the dSYM on the local
system, and failing that, tries the DBGShellCommands
command to find the dSYM.
3. It gets a dSYM. It reads the per-UUID plist in the dSYM.
The dSYM has a DBGSymbolRichExecutable kv pair pointing to
the binary on a network filesystem.
4. Using the binary on the network filesystem, lldb now goes
to find the dSYM.
5. It starts by looking for a dSYM next to the binary it found.
6. lldb is now reading the dSYM over a network filesystem,
ignoring the one it found on its local filesystem earlier.
Everything still *works* but it's much slower.
This would be a tricky one to write up in a testsuite case;
you really need the binary to not exist on the local system.
And LocateMacOSXFilesUsingDebugSymbols will only compile on
Mac OS X - even if I found a way to write up a test case, it
would not run anywhere but on a mac.
One change Greg wanted while I was touching this code was to
have LocateMacOSXFilesUsingDebugSymbols (which could be asked
to find a binary OR find a dSYM) to instead return a ModuleSpec
with the sum total of everything it could find. This
change of passing around a ModuleSpec instead of a FileSpec
was percolated up into ModuleList::GetSharedModule.
The changes to LocateMacOSXFilesUsingDebugSymbols look larger
than they really are - there's a lot of simple whitespace changes
in there.
I ran the testsuites on mac, no new regressions introduced

There were two versions of DoAttachToprocessWithId. One that takes
a pid_t, and the other which takes a pid_t and a ProcessAttachInfo.
There were no callers of the former version, and all of the
implementations of this version were simply forwarding calls to
one version or the other.

As part of getting ConnectionFileDescriptor working on Windows,
there is going to be alot of platform specific work to be done.
As a result, the implementation is moving into Host. This patch
performs the code move and fixes up call-sites appropriately.

This patch moves creates a thread abstraction that represents a
thread running inside the LLDB process. This is a replacement for
otherwise using lldb::thread_t, and provides a platform agnostic
interface to managing these threads.

This patch moves the logic of many common socket operations into
its own class lldb_private::Socket. It then modifies the
ConnectionFileDescriptor class, and a few users of that class,
to use this new Socket class instead of hardcoding socket logic
directly.
Finally, this patch creates a common interface called IOObject for
any objects that support reading and writing, so that endpoints
such as sockets and files can be treated the same.

It builds cleanly against TOT llvm with xcodebuild. I updated the
cmake files by visual inspection but did not try a build. I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.
In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

pure virtual base class and made StackFrame a subclass of that. As
I started to build on top of that arrangement today, I found that it
wasn't working out like I intended. Instead I'll try sticking with
the single StackFrame class -- there's too much code duplication to
make a more complicated class hierarchy sensible I think.

defines a protocol that all subclasses will implement. StackFrame
is currently the only subclass and the methods that Frame vends are
nearly identical to StackFrame's old methods.
Update all callers to use Frame*/Frame& instead of pointers to
StackFrames.
This is almost entirely a mechanical change that touches a lot of
the code base so I'm committing it alone. No new functionality is
added with this patch, no new subclasses of Frame exist yet.
I'll probably need to tweak some of the separation, possibly moving
some of StackFrame's methods up in to Frame, but this is a good
starting point.

Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging
The plug-in interface changes:
Modified the lldb_private::PluginInterface class that all plug-ins inherit from:
Changed:
virtual const char * GetPluginName() = 0;
To:
virtual ConstString GetPluginName() = 0;
Removed:
virtual const char * GetShortPluginName() = 0;
- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names.
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

To not be virtual. The lldb_private::Thread now handles the correct caching and will call a new pure virtual function:
namespace lldb_private {
class Thread
{
virtual bool
CalculateStopInfo() = 0;
}
}
This function must be overridden by thead lldb_private::Thread subclass and the only thing it needs to do is to set the Thread::StopInfo() with the current stop reason and return true, or return false if there is no stop reason. The lldb_private::Thread class will take care of calling this function only when it is required. This allows lldb_private::Thread subclasses to be a bit simpler and not all need to duplicate the cache and invalidation settings.
Also renamed:
lldb::StopInfoSP
lldb_private::Thread::GetPrivateStopReason();
To:
lldb::StopInfoSP
lldb_private::Thread::GetPrivateStopInfo();
Also cleaned up a case where the ThreadPlanStepOverBreakpoint might not re-set its breakpoint if the thread disappears (which was happening due to a bug when using the OperatingSystem plug-ins with memory threads and real threads).
