Summary: This patch adds SWIG typemaps that can convert arbitrary python file objects into lldb_private::File. A SBFile may be initialized from a python file using the constructor. There are also alternate, tagged constructors that allow python files to be borrowed, and for the caller to control whether or not the python I/O methods will be called even when a file descriptor is available.I Reviewers: JDevlieghere, jasonmolenda, labath Reviewed By: labath Subscribers: zturner, amccarth, lldb-commits Tags: #lldb Differential Revision: https://reviews.llvm.org/D68188 llvm-svn: 374225
