Thus all can be disabled at compile time. It would be easy to
make enabling/disabling a run-time option too.

General Cleanups
* Use { after if consistently in xc_ptrace.c and xc_ptrace_core.c
(But not in xc_ptrace_core() which should be removed shortly)
* Remove duplicate code and centralise around xc_ptrace.h
* Avoid ifing values covered by case in xc_ptrace()
- PTRACE_GETREGS, PTRACE_GETFPREGS and PTRACE_GETFPXREGS are grouped into
a single case, and then with the exception of a call to FETCH_REGS(),
different code is executed based on ifing the values covered by the
case. The PTRACE_GETFPREGS and PTRACE_GETFPXREGS code is actually a
duplicate. This patch breaks the code out to two different cases.
Error Handling
* Eliminate FETCH_REGS macro as it forces several functions
to have an otherwise uneeded error_out label, mittigating
any code savins.
* Rework error handling in xc_ptrace().
- Remove FETCH_REGS as above
- Make sure that all dom0 errors are caught
- Make sure errno is always set on error
* Eliminate gotos in xc_ptrace_core.c that do nothing but return
