Add TestTargetAPI.py:

// When stopped on breakppint 1, and then 2, we can get the line entries using
// SBFrame API SBFrame.GetLineEntry().  We'll get the start addresses for the
// two line entries; with the start address (of SBAddress type), we can then
// resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress().
//
// The two symbol context should point to the same symbol, i.e., 'a' function.


Add two utility functions to lldbutil.py:

o get_stopped_threads(process, reason):

  return the list of threads with the specified stop reason or an empty list if not found

o get_stopped_thread(process, reason):

  return the first thread with the given stop reason or None if not found
