don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

    rdar://problem/8557095 lldb disas crashed (from lldb developer)

lldb does not crash in that case.  Also added
support for checking Objective-C class validity
in the Version 1 runtime as well as Version 2
runtimes with varying levels of available debug
support.

Added a top level Timer to the interpreter execute command.  Also added an option to pass the depth to "log timer enable".  That allows you to time just command execution with:

log timer enable 1
<command>
log timer dump

fixed them.  Added DISALLOW_COPY_AND_ASSIGN to classes that should
not be bitwise copied.  Added default initializers for member
variables that weren't being initialized in the ctor.  Fixed a few
shadowed local variable mistakes.

adding support into lldb_private::Process:

    virtual uint32_t
    lldb_private::Process::LoadImage (const FileSpec &image_spec, 
                                      Error &error);

    virtual Error
    lldb_private::Process::UnloadImage (uint32_t image_token);

There is a default implementation that should work for both linux and MacOSX.
This ability has also been exported through the SBProcess API:

    uint32_t
    lldb::SBProcess::LoadImage (lldb::SBFileSpec &image_spec, 
                                lldb::SBError &error);

    lldb::SBError
    lldb::SBProcess::UnloadImage (uint32_t image_token);

Modified the DynamicLoader plug-in interface to require it to be able to 
tell us if it is currently possible to load/unload a shared library:

    virtual lldb_private::Error
    DynamicLoader::CanLoadImage () = 0;

This way the dynamic loader plug-ins are allows to veto whether we can 
currently load a shared library since the dynamic loader might know if it is
currenlty loading/unloading shared libraries. It might also know about the
current host system and know where to check to make sure runtime or malloc
locks are currently being held.

Modified the expression parser to have ClangUserExpression::Evaluate() be
the one that causes the dynamic checkers to be loaded instead of other code
that shouldn't have to worry about it.

RegisterContextLLDB holds a reference to the SymbolContext
in the vector of Cursors that UnwindLLDB maintains.  Switch
UnwindLLDB to hold a vector of shared pointers of Cursors
so this reference doesn't become invalid.

the end of the list. We had an issue in the MacOSX dynamic loader where if
we had shlibs:
1 - a.out
2 - a.dylib
3 - b.dylib

And then a.dylib got unloaded, we would unload b.dylib due to the assumption
that only shared libraries could come off the end of the list. We now properly
search and find which ones get loaded.

Added a new internal logging category for the "lldb" log channel named "dyld".
This should allow all dynamic loaders to use this as a generic log channel so
we can track shared library loads and unloads in the logs without having to 
have each plug-in make up its own logging channel.

ptrace thread update that was replying to the SIGSTOP was also causing the
process to not really be sigstop'd any more so then the call to ptrace
detach was failing, and when debugserver exited the attached process
was being killed.  Now the ptrace thread update does not disturb the sigstop
state of the thread, so the detach works properly.
