gsdx-hw: Re enable automatic mipmapping for Jak 1 and 3.

Issue #2916 has been resolved in #3076

GSdx-hw OGL: log if tex size gt PBO segment size.

Texture data may be corrupted in this case due to missing
fences synchronization.

GSdx-hw OGL: fix PBO pool map size.

Round up mapping size for alignment before computing
wrapped pointer.
Avoids memcpy after end of PBO buffer.

PCSX2: Avoid hang when switching renders with hotkey. (#3072)

Comment out the fix for the moment, since Travis hates me.

One more try here. Make harfbuzz optional instead of required for the moment, and worry about travis once it's on distributions with pango 1.44+.

Add harfbuzz to travis as well.

Add harfbuzz as a dependency to play nice with pango 1.44+.

Revert "3rdparty/pthreads4w: Fixup process exit logic. (#3056)"

This reverts commit af6f04020225eaf3239bc9b4542f4afd84560540.

Revert "3rdparty/pthreads4w: Ensure on_process_init early execution. (#3073)"

This reverts commit 88a02941f698577ecc45450308269f57e1d066ad.

3rdparty/pthreads4w: Ensure on_process_init early execution. (#3073)

This fixes a semi-consistent regression introduced by #3056, where on_process_exit would execute before other destructors relying on pthreads.

Now on_process_init has been moved to an earlier section of static initializers, ensuring it will be initialized first. Previously, this initializer was placed in the same section as any other initializer, making their order of execution non-deterministic across compilations - for example, I was unable to reproduce this issue as soon as I forced pthreads4w.c to recompile last!

GSdx: Fix mipmap SSE2 code for linear mipmap nearest filter. (#3064)

Fixes a regression introduced in e728a14c19eb55ea867cbf27d5985f97ed130a9e

GSdx-hw: Add Jak 1 JP and Jak 3 EU crc ids.

GSdx-hw: Add a crc id for Jak 1 US region.

GSdx-hw TC: improve search tex in RT

Fixes eyes rendering in Jak games both ingame and in cutscenes.
Previous method yielded no eyes in Jak 2/3/X cutscenes.

- Generalized offset search logic with caching system (works for BW > 1
and any PSM, limited to PSMCT32 for now)
- CRC Flags mechanism for default behavior enabling in Jak games

GSdx-hw TC: invalidate Source with Target TEX0

Fixes eyes blinking in Jak games with tex in rt search
enabled.

- Target TEX0 in Source is Source TEX0 if the Source is
not build from Target, otherwise it is the Target TEX0,
allowing improved Source invalidation

GSdx-hw TC: fix Target::Inside check

- inclusion shall not be strict only on start side

GSdx-hw TC: fix end block computations

- compute bottom right texel block as last valid block

GSdx-hw: SwSpriteRender, fix drawing region

GSdx-hw: SwSpriteRender, improve no rast. check
