mips32, add support for micromips in debug mode
Micromips is 16bit oriented, branch and jumps are
16 bit based. The upper half 16bits of a 32bit instruction
with the major opcode, must go first in the instruction
stream, hence the SWAP16 macro and swap16 array function,
needed if the code is written as 32 bit word in little endian
cores. Endianess info added to ejtag_iinfo. Pointer to
ejtag_info and isa field added to pracc context.
MIPS32 code are renamed to MIPS32_ISA_...
To select the isa, the new code has an additional isa parameter
(1 for micromips, 0 for mips32).
In JR instruction the isa bit must be set to execute
micromips code.
The suffix u is added to the OP codes to avoid signed/unsigned
comparison errors and to make sure the right shift is
performed logically.
The isa in debug mode is updated in the poll function.
Code for miniprograms, in kernel mode, need to be converted.
CFI code only for mips32.

mips32, add microMips instruction subset
Only reencoded MIPS32 instructions. Added some instructions
for crc code. Micromips isa in debug mode is only needed for
pic32mm cores. Pic32mz seems that only works with MIPS32
isa when in debug mode.

mips32, add option to avoid check in last instruction
This option is needed, for example, when exiting
debug mode in bmips targets. The last instruction
is a NOP, not a DERET. When working in async mode
this check is not done, mips32_pracc_queue_exec() pass
the parameter to mips32_pracc_exec() and never use it.

mips32, add realloc code
If max_code is reached realloc memory. If fails to realloc
the error is propagated and every call to pracc_add() returns
immediately. The exec function logs the error.

mips32, change in pracc_list for dynamic allocation
pracc_list points to an array with code in the lower half
and addr in the upper half. Change it to a struct with
an instruction field and an address field.
Requiered to make reallocation easier.
As a side effect the code is less quirky.
MacOSX tool chain defines __unused in "sys/cdefs.h", causing a collision.
Remove the local define to avoid polluting the compilers internal
symbol namespace.

mips32, mips32_pracc_finish() queued only
In most of the cases there is no need to request execution,
the check for a new pracc access already does it.
Requesting execution if not needed makes execution slower and
code larger due the additional checks.
Reduce code in fasdata transfer function.
Call for execution when exiting debug.
