Result is incompatible with previous version. Those just shouldn't be

There was possible timing information leaking from failed decryptions,
new code makes the whole thing fail in almost the same time in all
cases.

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).

A minor bug was discovered in padding of short message signatures. If is
silently fixed, causing some (very minor) incompatibility of signatures

09136ef046 actions: better keyring opening behavior 
This delays opening (and locking) the keyring until all input has been
processed, and all possible errors that would make a chance that the
keyring doesn't have to be opened have been checked for.

Whole purpose was to enable codecrypt to be chained with pipes in UNIX-y way,
like this primitive certificate creation:

(echo "At `date` I certify this is The Key:" ; ccr -pa -F "the key") | ccr -s

b5ae7ca4dd algos_sig: added H=20 fmtseq variant 
...that provide around 1 million signatures per key. That seems more
than sufficient for human usage.

Note that generating the key takes 16 times longer than for already
present algorithms (that have H=16). On my computer, it is around 4
minutes for fmtseq128N20 and 16 minutes for fmtseq256N20.

18449bdc8a arcfour: greatly increase discard parameters 
Okay, this thing got public so it's time to make the RC4 rugged. Not
that I'd know about something that would break current implementation,
but it's nice to at least do the recommended discard correctly.

We'll probably be adding better symmetric ciphers anyway.

Note that this is an incompatible change (again). FMTSeq private keys
will need to be replaced. Existing signature validity doesn't change.
Encrypted messages will not be possible to decrypt.

24bd5bd185 algos_sig: new support for fmtseq192 
It's quite rational to have such algorithm. 256-bit security is usually
an overkill, and this has two times smaller signatures (around 9.5kB) is
_so_ much faster. Use it.
