Merge branch 'da/darwin'

Newer MacOS X encourages the programs to compile and link with
their CommonCrypto, not with OpenSSL.

* da/darwin:
  imap-send: eliminate HMAC deprecation warnings on Mac OS X
  cache.h: eliminate SHA-1 deprecation warnings on Mac OS X
  Makefile: add support for Apple CommonCrypto facility
  Makefile: fix default regex settings on Darwin
