*  mips-tdep.c (unpack_mips16): Fixed instruction decoding, lots of
 	bit pattern interpretations. mips_fetch_instruction does not work
 	for 16 bit instructions. Some confusion remains about sign
 	extension in backward branches.
	(mips32_relative_offset): Sign extension
	(mips32_next_pc): Major debugging, bit pattern interpretation
	(print_unpack): debugging printf
	(fetch_mips_16): new funtion, key on PC low bit, not symbol table
	(mips16_next_16): Initial major debugging of this function. Lots
 	of bit pattern mistakes.
	(mips_next_pc): key on low bit of PC, not symbol table.
	* symfile.c(generic_load) : Added a download verification which
 	reads back the loade code. Download chunk size is now a defined
 	macro. Fixed a bug in which downloading slips into loading one
 	byte at a time. Lower level functions in monitor.c can load long
 	sequences of bytes and make use of these fixups.  Referencing
 	bfd-start_address directly was incorrectly getting zero for start.
