builtins: Makefile clean-up
This cleans up the build procedure for built-in commands by: - generating mostly redundant definition of BUILT_INS from BUILTIN_OBJS in the Makefile, - renaming a few files to make the above possible, and - sorting the built-in command table in git.c. It might be a good idea to binary search (or perfect hash) the built-in command table, but that can be done later when somebody feels like. Signed-off-by: Junio C Hamano <junkio@cox.net>
