enabled after we'd found a few bugs that were caused by shadowed
local variables; the most important issue this turned up was
a common mistake of trying to obtain a mutex lock for the scope
of a code block by doing

        Mutex::Locker(m_map_mutex);

This doesn't assign the lock object to a local variable; it is
a temporary that has its dtor called immediately.  Instead,

        Mutex::Locker locker(m_map_mutex);

does what is intended.  For some reason -Wshadow happened to
highlight these as shadowed variables.

I also fixed a few obivous and easy shadowed variable issues
across the code base but there are a couple dozen more that
should be fixed when someone has a free minute.

trying to mmap a file fails so parent caller function can 
provide helpful information to use about what went wrong.

to fix the issues we run into on darwin even though the docs don't
seems to say it will.

Removed an extra call to close that was causing problems and also
now use the Host::File class to open the file.

CommandCompletions.cpp and DataBufferMemoryMap.cpp.  The file type
part of the st_mode struct member is not a bitmask.

Something changed in commit r129112 where a few standard headers vanished from
the include chain when building on Linux.  Fix up by including limits.h for
INT_MAX and PATH_MAX where needed, and stdio.h for printf().

GDBRemoteCommunicationServer classes. This involved adding a new packet
named "qSpeedTest" which can test the speed of a packet send/response pairs
using a wide variety of send/recv packet sizes.

Added a few new connection classes: one for shared memory, and one for using
mach messages (Apple only). The mach message stuff is experimental and not 
working yet, but added so I don't lose the code. The shared memory stuff
uses pretty standard calls to setup shared memory.

We have a common unix implementation in lldb/source/Host/common/FileSpec.cpp.

enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.
