Demangler Plugins

[plafosse]

Provide a generic API for users to add their own name demanglers to be run during analysis. This can currently be done after the fact, but it would be nice if it could be integrated.

We should provide two api's, Demangle() and DemangleToType()
The DemangleToType() api will return a BNType object containing a type tree for the given type, Demangle() will simply return a string.

Example workaround:

import subprocess
for func in bv.functions:
    if func.name.startswith("__T") or func.name.startswith("_T"):
        func.name = subprocess.check_output(["/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-demangle", "-compact", func.name])
