rtos: support gdb_get_register_packet

Browse Source 
This patch adds support for p packet responses by targets configured
with RTOS support. This change required moving to a rtos_reg struct,
which is similar to struct reg used by targets, which resulted in
needing to update each stacking with register numbers. This patch also
allows targets with non-linear register numbers to function with RTOSes
as well.
