The bswap that's needed for system mode isn't required for
user mode, and in fact breaks debugging.

[agraf: fix apple gdbstub implementation]

The Apple gdbstub protocol is different from the normal gdbstub protocol
used on PowerPC. Add support for the different variant, so that we can use
Apple's gdb to debug guest code.
Keep in mind that the switch is a compile time option. We can't detect
during runtime whether a gdb connecting to us is an upstream gdb or an
Apple gdb.

This patch allows registers to be properly read from and written to
when using the gdbstub to debug a ppc guest running in little
endian mode.

This patch extracts the method to determine a register's size
into a separate function.

This avoids polluting the global namespace with a non-prefixed macro and
makes it obvious in the call sites that we return.
Semi-automatic conversion using, e.g.,
sed -i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target-*/gdbstub.c
followed by manual tweaking for sparc's GET_REGA() and Coding Style.
