add crypto shared libraries
mark idea and mdc2 libraries obsolete.
remove mdc2 and idea handling
MKCRYPTO_{IDEA,MDC2} is no more
MKCRYPTO_IDEA is no more
no more CRYPTO_{IDEA,MDC2}
more MKCRYPTO_IDEA and MKCRYPTO_MDC2 removal (resp, adjustment to IDEA and
MBC2 now always being included)
MKCRYPTO_RC5 now builds shared libs, add the missing files to sets
