While converting compat system call handlers to work on 32-bit architectures, I found a number of types used in those handlers that are identical between all architectures.
Let's move all the identical ones into asm-generic/compat.h to avoid having to add even more identical definitions of those types.
For unknown reasons, mips defines __compat_gid32_t, __compat_uid32_t and compat_caddr_t as signed, while all others have them unsigned. This seems to be a mistake, but I'm leaving it alone here. The other types all differ by size or alignment on at least on architecture.
compat_aio_context_t is currently defined in linux/compat.h but also needed for compat_sys_io_getevents(), so let's move it into the same place.
While we still have not decided whether the 32-bit time handling will always use the compat syscalls, or in which form, I think this is a useful cleanup that we can merge regardless.
