gdbstub: move chunks of user code into own files

The process was pretty similar to the softmmu move except we take the
time to split stuff between user.c and user-target.c to avoid as much
target specific compilation as possible. We also start to make use of
our shiny new header scheme so the user-only helpers can be included
without the rest of the exec/gsbstub.h cruft.

As before we split some functions into user and softmmu versions

bsd-user/signal.c: Add si_type argument to queue_signal

Mirror the linux-user practice and add a si_type argument to queue
signal. This will be transported as the upper 8 bits in the si_type
element of siginfo so that we know what bits of the structure are valid
and so we can properly implement host_to_target_siginfo_noswap and
tswap_siginfo. Adapt the one caller of queue_signal to the new
interface. Use all the same names as Linux (except _RT which we don't
treat differently, unlike Linux), though some are unused. Place this
into signal-common.h since that's a better place given bsd-user's
structure. Move prototype of queue_signal to signal-common.h to mirror
linux-user's location.
