Jason Molenda 62c747517c Check if null buffer handed to SBProcess::ReadMemory 
Add a check for a null destination buffer in SBProcess::ReadMemory,
and return an error if that happens.  If a Python SB API script
tries to allocate a huge amount of memory, the malloc done by the
intermediate layers will fail and will hand a null pointer to
ReadMemory.  lldb will eventually crash trying to write in to that
buffer.

Also add a test that tries to allocate an impossibly large amount
of memory, and hopefully should result in a failed malloc and hitting
this error codepath.
