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.

- * This file manages the OpenGL API dispatch layer.
- * The dispatch table (struct _glapi_table) is basically just a list
- * of function pointers.
- * There are functions to set/get the current dispatch table for the
- * current thread and to manage registration/dispatch of dynamically
- * added extension functions.
- *
- * It's intended that this file and the other glapi*.[ch] files are
- * flexible enough to be reused in several places:  XFree86, DRI-
- * based libGL.so, and perhaps the SGI SI.
- *
- * NOTE: There are no dependencies on Mesa in this code.
- *
- * Versions (API changes):
- *   2000/02/23  - original version for Mesa 3.3 and XFree86 4.0
- *   2001/01/16  - added dispatch override feature for Mesa 3.5
- *   2002/06/28  - added _glapi_set_warning_func(), Mesa 4.1.
- *   2002/10/01  - _glapi_get_proc_address() will now generate new entrypoints
- *                 itself (using offset ~0).  _glapi_add_entrypoint() can be
- *                 called afterward and it'll fill in the correct dispatch
- *                 offset.  This allows DRI libGL to avoid probing for DRI
- *                 drivers!  No changes to the public glapi interface.

- * \name Current dispatch and current context control variables
- *
- * Depending on whether or not multithreading is support, and the type of
- * support available, several variables are used to store the current context
- * pointer and the current dispatch table pointer.  In the non-threaded case,
- * the variables \c _glapi_Dispatch and \c _glapi_Context are used for this
- * purpose.
- *
- * In the "normal" threaded case, the variables \c _glapi_Dispatch and
- * \c _glapi_Context will be \c NULL if an application is detected as being
- * multithreaded.  Single-threaded applications will use \c _glapi_Dispatch
- * and \c _glapi_Context just like the case without any threading support.
- * When \c _glapi_Dispatch and \c _glapi_Context are \c NULL, the thread state
- * data \c _gl_DispatchTSD and \c ContextTSD are used.  Drivers and the
- * static dispatch functions access these variables via \c _glapi_get_dispatch
- * and \c _glapi_get_context.
- *
- * There is a race condition in setting \c _glapi_Dispatch to \c NULL.  It is
- * possible for the original thread to be setting it at the same instant a new
- * thread, perhaps running on a different processor, is clearing it.  Because
- * of that, \c ThreadSafe, which can only ever be changed to \c GL_TRUE, is
- * used to determine whether or not the application is multithreaded.
- * 
- * In the TLS case, the variables \c _glapi_Dispatch and \c _glapi_Context are
- * hardcoded to \c NULL.  Instead the TLS variables \c _glapi_tls_Dispatch and
- * \c _glapi_tls_Context are used.  Having \c _glapi_Dispatch and
- * \c _glapi_Context be hardcoded to \c NULL maintains binary compatability
- * between TLS enabled loaders and non-TLS DRI drivers.
