[PATCH v2 02/21] abg-cxx-compat: more <functional> support: std::bind and friends

[Matthias Maennich]

Add abg_compat::{bind,function,placeholders} to the compatibility layer.
That is made use of in a later patch. As usual, for C++ standards that
natively support this functionality (C++11 and later), the native
implementation is aliased into the abg_compat namespace.

	* include/abg-cxx-compat.h: add support for
	  abg_compat::{bind,function,placeholders}
