Mirek Kratochvil d8f358e8ed mce_qcmdpc: decrease decoding failure rate 
The `online' modification of unsatisfied eqn counts caused increased rate of
decoding failures (verified experimentally). Use the variant that doesn't
modify the counts until next round.

Mirek Kratochvil dbce46b48a better configuration of crypto++ library 
This fixes issues on unixes without /usr/include/crypto++ and makes use of
pkgconfig to configure the package correctly.

Mirek Kratochvil 78a00ae3ce mce_qcmdpc: implement faster decoding 
This replaces the periodic recalculation of error correlations and the syndrome
by in-place modification. Bit flip is therefore a bit slower, but overall
decoding of the 256-bit secure variant fits in 200ms, and 128-bit variant
decodes under 20ms.

There still could be some (blatantly nondeterministic) method to do this using
FFT, research underway.

Mirek Kratochvil 3659cc837e xsynd: new stream cipher 
This one is especially cool. It is code based (yeyeye matches the
project name! :D ), it is provably secure (not like the others!) AAAND
is still quite fast (not fast as chacha though).
