mapi: Add mapi and share the code with glapi. Specifically, move all or most of glapi/glapi.c to mapi/u_current.c, glapi/glapi_execmem.c to mapi/u_execmem.c, glapi/glthread.[ch] to mapi/u_thread.[ch] and remove their dependencies on core Mesa headers.

#ifndef _U_CURRENT_H_
#define _U_CURRENT_H_
mapi: Add support for bridge mode. In bridge mode, mapi no longer implements glapi.h. It becomes a user of glapi.h. Imagine an app that uses both libGL.so and libGLESv2.so. There will be two copies of glapi in the app's memory. It is possible that _glapi_get_dispatch does not return what _glapi_set_dispatch set, if they access different copies of the global variables. The solution to this situation to build either one of the libraries as a bridge to the other. Or build both libraries as bridges to another shared glapi library.

glapi: Move public function/variable declarations to glapi.h. glapi defines an interface that is used by DRI drivers. It must not be changed in an ABI incompatible way. This commit moves all functions/variables belong to the interface to glapi.h. Instead of including u_current.h from glapi.h, u_current.h now includes glapi.h.
