Lawrence D'Anna 5750453020 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.

/*
lldb.swig

"The lldb module contains the public APIs for Python binding.
Some of the important classes are described here:
o SBTarget: Represents the target program running under the debugger.
o SBProcess: Represents the process associated with the target program.
o SBThread: Represents a thread of execution. SBProcess contains SBThread(s).
o SBFrame: Represents one of the stack frames associated with a thread. SBThread
contains SBFrame(s).
o SBSymbolContext: A container that stores various debugger related info.
o SBValue: Represents the value of a variable, a register, or an expression.
o SBModule: Represents an executable image and its associated object and symbol
files. SBTarget contains SBModule(s).
o SBBreakpoint: Represents a logical breakpoint and its associated settings.
SBTarget contains SBBreakpoint(s).
o SBSymbol: Represents the symbol possibly associated with a stack frame.
o SBCompileUnit: Represents a compilation unit, or compiled source file.
o SBFunction: Represents a generic function, which can be inlined or not.
o SBBlock: Represents a lexical block. SBFunction contains SBBlock(s).
o SBLineEntry: Specifies an association with a contiguous range of instructions
and a source file location. SBCompileUnit contains SBLineEntry(s)."

/*
Since version 3.0.9, swig's logic for importing the native module has changed in
a way that is incompatible with our usage of the python module as __init__.py
(See swig bug #769). Fortunately, since version 3.0.11, swig provides a way for
us to override the module import logic to suit our needs. This does that.
Older swig versions will simply ignore this setting.
