Subject: new api class: SBFile

Summary:
SBFile is a scripting API wrapper for lldb_private::File

This is the first step in a project to enable arbitrary python
io.IOBase file objects -- including those that override the read()
and write() methods -- to be used as the main debugger IOStreams.

Currently this is impossible because python file objects must first
be converted into FILE* streams by SWIG in order to be passed into
the debugger.
