Add flash algorithm support for the PIC32MX.
Still a few things todo but this dramatically decreases
the programing time, eg. approx programming for 2.5k test file.
- without fastload: 60secs
- with fastload: 45secs
- with fastload and algorithm: 2secs.
Add new devices to supported list.

- add mips support for target algorithms.
- added handlers for target_checksum_memory and target_blank_check_memory.
- clean up long lines

- add target_to_mips32 and target_to_m4k to match test of codebase.
- mips32_arch_state now shows if processer is running mips16e isa.

Uses chaining of command_registration structures to eliminate all
target_type register_callback routines. Exports the command_handler
registration arrays for those target types that are used by others.
Create a generic register_cache_invalidate(), and use it to
replace three all-but-identical core-specific routines:
- armv4_5_invalidate_core_regs()
- armv7m_invalidate_core_regs
- mips32_invalidate_core_regs() too.
Make cache->num_regs be unsigned, avoiding various errors.
Net code shrink and simplification.

Same deal: "register.h" got needlessly included all over the
place because of being in a few widely included headers.
So take it out of the header files which included it, and put
it in files which use it ... reduce needless interdependencies.
Also, don't need that extra "types.h" inclusion.

Most files in the tree seem to have ended up including this,
and *quite* needlessly ... only code implementing or using
breakpoints actually needs these declarations.

The quit entry point was not being invoked. Just a source
of confusion at this point. XScale ran 100x reset upon
quit, but that code made no sense, wasn't commented
and never invoke.

- Move the mips32_..._read_mem calls to top-level of read_mem function.
- Change: Only perform mips_m4k_read_mem conversion when retval == ERROR_OK.
- Prevents pointless conversions of bogus read values after failures.
- Eliminate retval variable from mips_m4k_write_mem; return directly.
- Move declaration of retval variable to point of first use.
- Remove the now redundant switch statements testing size:
- argument sanitizing already covers these cases.

This patch helps fix MIPS big endian (elf32-tradbigmips) targets.
If "-endian big" is not set in target create, the endianess defaults to
little. mw and md commands will still work, but binary file loads will
have the incorrect word order loaded into memory.
The EJTAG processor access data register (PrAcc) is little endian
regardless of the CPU endianness; it is always loaded LSB first. This
is confirmed by the fact that mips_ejtag_drscan_32() uses buf_set_u32()
to load the scan field; buf_set_u32() is a little-endian formatter. For
big endian targets, data buffers have to be modified so the LSB of each
u32 or u16 is at the lower (first) memory location. If the drscan
out_value word order is set using buf_set_u32() then it makes sense to
also fixup the in_value with buf_get_u32(); a symmetry argument. This
has no affect on little endian hosts.

ejtag_info->ejtag_ctrl variable. It was being overwritten by the value read back from the EJTAG CONTROL register. Because of the way this register works you do not want to use the value returned to write the register, you always want to write the bits explicitly.
The second patch just reduces the DMA retries to 0 in anticipation of removing the retry code altogether.

Also target_process_reset() is now simpler and has error handling,
e.g. if assert reset fails, then target_process_reset() will propagate
that error.
cmd_ctx was passed in to examine(), which is wrong - removed that.
