First (working) implementation. Hugely WIP.

NAMELY: DO NOT RUN ON A PW2!!!
That's probably more correct.

Hahaha. I'm already rusty with C pointers, this is killing me xD.

Update FT
Merge pull request #202 from NiLuJe/master

Tweak Android *FLAGS
fix(kobo ffi): add missing mxcfb_alt_buffer_data_org cdecl
fix(build): pass CFLAGS to assembler in cmake

this builds libpng with neon support
Fix ffi/mxcfb_kindle_h.lua

Hackishly generated with updated version of gcc-lua & co.
Currently battling updter our koreader-misc tools to automate that.
Start converting stuff for the updated ffi tools
Make the rename clearer.
Refresh ffi stuff w/ update gcc-lua/gcc-lia-cdecl

Minus some stuff that diverge too much because of my system.
Thankfully, the only thing that appeared truly broken w/ the previous
iteration was mxcfb_kindle_h.lua, so it's not terribly critical.
Oops, had forgotten that, nice catch.

Stolen from houqp's 1fbd16d ;).
Detect the first refresh call in a smarter way
Timestamps!
Turns out os.date sucks. Not high res.
Implement device detection.

We now handle the PW2 correctly, and the Touch/PW1 should behave like
the stock reader (only waiting for full updates, unlike the PW2).
Merge remote-tracking branch 'upstream/master' into mxcb_wait_for
Build FT without HarfBuzz support.

While it's nice for CFF auto-hinting, harfbuzz itself has a build dep to
FT, so the circular dependency is kind of a bitch when x-compiling.
Fix FreeType ffi

Not quite sure how this managed to work before :D.
We're possibly using that...

So make sure it doesn't break on regen.
