Detect SSE2 support

Compilation on an older 32-bit Athlon XP chip fails with the error
"./Utils/AEUtil.h:50:12: error: '__m128i' does not name a type"
This is because the __m128i type is only available on SSE2 platforms.
Modify the preprocessor logic to detect SSE and SSE2 support separately.

The "emmintrin.h" header should only be included on SSE2 platforms as
well.

[rbp/omxplayer] Support ff/rew

Big missing feature added for Pi.
It works by increasing the clock and discarding audio when at 2x and 4x.
For rewind and 8x and higher, it uses a different scheme. It pauses video, and single steps.

For both schemes it uses the normal dvd player mechanism of seeking when the clock has diverged by too much.

Notes:
dvdplayer still decodes (then discards) audio when ff/rew.
I'm skipping the decode step (too much cpu at 4x realtime).

I've made GetTime return m_clock.GetClock() when ff/rew. (m_State.time is too jumpy).
