Richard Henderson 95059f9c31 include/exec: Change reserved_va semantics to last byte 
Change the semantics to be the last byte of the guest va, rather
than the following byte.  This avoids some overflow conditions.

Alex Bennée 4692a86f1c include: split target_long definition from cpu-defs 
While we will continue to include this via cpu-defs it is useful to be
able to define this separately for 32 and 64 bit versions of an
otherwise target independent compilation unit.

Alex Bennée c566080cd3 gdbstub: move syscall handling to new file 
Our GDB syscall support is the last chunk of code that needs target
specific support so move it to a new file. We take the opportunity to
move the syscall state into its own singleton instance and add in a
few helpers for the main gdbstub to interact with the module.

I also moved the gdb_exit() declaration into syscalls.h as it feels
pretty related and most of the callers of it treat it as such.

Alex Bennée 4ea5fe997d gdbstub: move register helpers into standalone include 
These inline helpers are all used by target specific code so move them
out of the general header so we don't needlessly pollute the rest of
the API with target specific stuff.

Note we have to include cpu.h in semihosting as it was relying on a
side effect before.

Alex Bennée d96bf49ba8 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
