[PATCH/RFA] Updated: Generic OS ABI handling

[Jason R Thorpe <thorpej at wasabisystems dot com>]

Changes from the last:

	* Notion of "generic" and "specific" sniffers, and a
	  "specific" sniffer added for ARM ELF.

	* Docs updated to reflect above, plus other comments from
	  Eli.

        arm_abi_handler_list, arm_gdbarch_register_os_abi): Remove.
        (get_elfosabi): Rename to...
        (arm_elf_osabi_sniffer): ...this.  Adjust to use generic OS
        ABI framework support routines.
        (arm_gdbarch_init): Use generic OS ABI framework.
        (arm_dump_tdep): Likewise.
