Client: Compiler
Patch: Nobuaki Sukegawa, rebased by dtmuller

Also fixed by dtmuller:
* Add plugin namespace for erlang language binding
* Fix unit test test_const_value
* Don't clear type cache with every t_program conversion
* Type "wb" may not be supported by popen on non-Windows platforms
* Fix constness of AST type signatures
