Edward Tomasz Napierala 7d681ad774 crypt_r(3): fix reentrancy problems with DES
This code was originally written for non-reentrant crypt(3).
In 5f521d7ba7, a thread-safe crypt_r(3) was introduced.  However,
it looks like the DES implementation is still not re-entrant;
routines like setup_salt() or des_setkey() still use global
variables.

Instead of something drastic, eg removing DES support altogether,
just mark those variables as thread-local.  This adds about 30kB
of data per thread.

Given that this only applies to DES, I think the impact is minimal.
