Update to bsnes v038r08? release.

Another WIP, but nothing visible to end users. Still get it if you
don't have 07 for the nice speedup.

Mostly source-cleaning stuff.
- removed 'uint' type, replaced all instances with the proper unsigned
int.
- removed as many headers as I could from the global interface.hpp
file, including only in the cores that need each of them. Should help
compile time. Though I still have a lot of global header includes due
to needing ultra-hot sections of code inlined.
- added include protection bumpers to the CPU+SMP opcode core
generated files
- added const-correctness to a few more classes.
- updated S-RTC and SPC7110 time to handle time_t overflow: it's now
Y2K38 proof even on 32-bit signed time_t systems, and the file format
remains unchanged. But it adds one limitation that you'll lose your
time if you wait ~34 years before loading your last save game. I think
that's reasonable for now. Once 64-bit time_t systems are ubiquitous,
we should be able to trivially expand that without breaking old saves.

Relevant code (I tested with int16_t, uint16_t, int32_t, uint32_t,
int64_t and uint64_t):

      time_t diff
      = (current_time >= rtc_time)
      ? (current_time - rtc_time)
      : (std::numeric_limits<time_t>::max() - rtc_time + current_time
    + 1);  //compensate for overflow
      if(diff > std::numeric_limits<time_t>::max() / 2) diff = 0;
    //compensate for underflow


Avoided the obvious (y-x)&<time_t>::max() just in case there's some
crazy platform where the value != (some power of 2)-1. Modulus
(max()+1) won't work there either, as it'll overflow if
sizeof(unsigned) == sizeof(time_t). The +1 might throw it off by a
second on one's complement system, but I don't really care :P

Anyone with GCC 4.3 want to try something for me? Try modifying
src/lib/nall/platform.hpp and change #define alwaysinline
__attribute__((always_inline)) to:
    #define alwaysinline __attribute__((always_inline))
    __attribute__((hot))


... and let me know the FPS difference you get in some arbitrary game,
please :D

It's supposed to be like manual-PGO.
