Added a missing API call in SBTarget that enables one to get

anything in a SBSymbolContext filled in given an SBAddress:

SBSymbolContext
SBTarget::ResolveSymbolContextForAddress (const SBAddress& addr, uint32_t resolve_scope);

Also did a little cleanup on the ProcessGDBRemote stdio file handle
code.
