Subject: [PATCH] glapi: generate ES dispatch headers from core mesa

GLESv1 and GLESv2 have their own dispatch.h and remap_helper.h.  These
headers are only used by api_exec_es1.c and api_exec_es2.c in core mesa.
Move the rules to generate them from glapi to core mesa.

Reviewed-by: Brian Paul <brianp@vmware.com>

[olv: updated after reviewing to fix SCons build]
