windows: use a static lib of pthreads 2.9.1

built with nmake clean VC-static
m7, add sources from djm34 repo (v6+)

fix most part of indentation and headers

but ive copied whirlpool and x17 stuff in a new m7 folder
m7: adapt cpu-miner for m7 stratum (working)

proper commit based on djm34's work
m7: forgot to indent some cuda files

and remove unused variables...
m7: fine tune threads and max registers

TODO:

on 750 Ti, this version of ripemd seems very slow...
It could be made in 3ms and take actually 25ms

whirlpool can also be optimized, with last djm code...
m7: update vstudio project

need a new mpir lib, available in my project releases on github
prepare release 1.4

update README
