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.

- * Thread support for gl dispatch.

- * Initial version by John Stone (j.stone@acm.org) (johns@cs.umr.edu)
- *                and Christoph Poliwoda (poliwoda@volumegraphics.com)
- * Revised by Keith Whitwell

- * DOCUMENTATION
- *
- * This thread module exports the following types:
- *   _glthread_TSD     Thread-specific data area
- *   _glthread_Thread  Thread datatype
- *   _glthread_Mutex   Mutual exclusion lock
- *
- * Macros:
- *   _glthread_DECLARE_STATIC_MUTEX(name)   Declare a non-local mutex
- *   _glthread_INIT_MUTEX(name)             Initialize a mutex
- *   _glthread_LOCK_MUTEX(name)             Lock a mutex
- *   _glthread_UNLOCK_MUTEX(name)           Unlock a mutex
- *
- * Functions:
- *   _glthread_GetID(v)      Get integer thread ID
- *   _glthread_InitTSD()     Initialize thread-specific data
- *   _glthread_GetTSD()      Get thread-specific data
- *   _glthread_SetTSD()      Set thread-specific data
