add mips n32 port (ILP32 ABI for mips64) based on patch submitted by Jaydeep Patil, with minor changes.

deduplicate mips64/n32 syscall clobbered register lists this patch is not purely non-functional changes, since before, $8 and $9 were wrongly in the clobberlist for syscalls with fewer than 5 or 6 arguments. of course it's impossible for syscalls to have different clobbers depending on their number of arguments. the clobberlist for the recently-added 5- and 6-argument forms was correct, and for the 0- to 4-argument forms was erroneously copied from the mips o32 ABI where the additional arguments had to be passed on the stack. in making this change, I reviewed the kernel sources, and $8 and $9 are always saved for 64-bit kernels since they're part of the syscall argument list for n32 and n64 ABIs.

clean up mips64/n32 syscall asm constraints ever since inline syscalls were added for (o32) mips in commit 328810d32524e4928fec50b57e37e1bf330b2e40, the asm has nonsensically loaded the syscall number, rather than taking $2 as an input constraint to let the compiler load it. commit cfc09b1ecf0c6981494fd73dffe234416f66af10 improved on this somewhat by allowing a constant syscall number to propagate into an immediate, but missed that the whole operation made no sense. now, only $4, $5, $6, $8, and $9 are potential input-only registers. $2 is always input and output, and $7 is both when it's an argument, otherwise output-only. previously, $7 was treated as an input (with a "1" constraint matching its output position) even when it was not an input, which was arguably undefined behavior (asm input from indeterminate value). this is corrected.

clean up mips64/n32 syscall asm constraints ever since inline syscalls were added for (o32) mips in commit 328810d32524e4928fec50b57e37e1bf330b2e40, the asm has nonsensically loaded the syscall number, rather than taking $2 as an input constraint to let the compiler load it. commit cfc09b1ecf0c6981494fd73dffe234416f66af10 improved on this somewhat by allowing a constant syscall number to propagate into an immediate, but missed that the whole operation made no sense. now, only $4, $5, $6, $8, and $9 are potential input-only registers. $2 is always input and output, and $7 is both when it's an argument, otherwise output-only. previously, $7 was treated as an input (with a "1" constraint matching its output position) even when it was not an input, which was arguably undefined behavior (asm input from indeterminate value). this is corrected.

deduplicate mips64/n32 syscall clobbered register lists this patch is not purely non-functional changes, since before, $8 and $9 were wrongly in the clobberlist for syscalls with fewer than 5 or 6 arguments. of course it's impossible for syscalls to have different clobbers depending on their number of arguments. the clobberlist for the recently-added 5- and 6-argument forms was correct, and for the 0- to 4-argument forms was erroneously copied from the mips o32 ABI where the additional arguments had to be passed on the stack. in making this change, I reviewed the kernel sources, and $8 and $9 are always saved for 64-bit kernels since they're part of the syscall argument list for n32 and n64 ABIs.

remove mips/n32/64 stat struct hacks from syscall machinery now that we have a kstat structure decoupled from the public struct stat, we can just use the broken kernel structures directly and let the code in fstatat do the translation.

get/setsockopt: add fallback for new time64 SO_RCVTIMEO/SO_SNDTIMEO without this, the SO_RCVTIMEO and SO_SNDTIMEO socket options would stop working on pre-5.1 kernels after time_t is switched to 64-bit and their values are changed to the new time64 versions. new code is written such that it's statically unreachable on 64-bit archs, and on existing 32-bit archs until the macro values are changed to activate 64-bit time_t.
