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.

6da777e212 bsd-user: implement sysctlbyname(2) 
do_freebsd_sysctlbyname needs to translate the 'name' back down to a OID
so we can intercept the special ones. Do that and call the common wrapper
do_freebsd_sysctl_oid.

7adda6de6d bsd-user: do_freebsd_sysctl helper for sysctl(2) 
Implement the wrapper function for sysctl(2). This puts the oid
arguments into a standard form and calls the common
do_freebsd_sysctl_oid.

4cf41e8084 bsd-user: Don't truncate the return value from freebsd_syscall 
System call return values on FreeBSD are in a register (which is spelled
abi_long in qemu). This was being assigned into an int variable which
causes problems for 64bit targets.
