Enhance GAS's .section directive so that it can take numeric values for the flags and type fields. (ELF only)

gas	* doc/as.texinfo (.section): Document that numeric values can now
	be used for the flags and type fields of the ELF target's .section
	directive.  Add notes about the restrictions on setting flags and
	types.
	* config/obj-elf.c (obj_elf_change_section): Allow known sections
	to be given processor specific section types.  Allow processor and
	application specific flags of a section to be set after
	definition.
	(obj_elf_parse_section_letters): Handle parsing numeric values.
	(obj_elf_section_type): Handle parsing numeric values.
	(obj_elf_section): Allow numeric type values.
	* config/obj-elf.h (obj_elf_change_section): Update prototype.
	* testsuite/gas/elf/section10.d: New test.
	* testsuite/gas/elf/section10.s: Source file for new test.
	* testsuite/gas/elf/elf.exp: Run the new test.
	* testsuite/gas/i386/ilp32/x86-64-unwind.d: Remove dependency upon
	the description of the flags produced by readelf.
	* testsuite/gas/tic6x/scomm-directive-4.d: Likewise.
	* NEWS: Mention the new feature.

bfd	* elf-bfd.h (struct bfd_elf_special_section): Use unsigned values
	for length and type fields.  Use a signed value for the
	suffix_length field.

binutils* readelf.c (get_section_type_name): Add hex prefix to offsets
	printed for LOPROC and LOOS values.  Ensure that a result is
	always returned for the V850 target, even when an unrecognised
	processor specific value is encountered.
	(process_section_headers): Display key values in the order in
	which they appear to the user.  Add the "C (compressed)" value to
	the list.

	description of the flags produced by readelf.
