Support GnuTLS as an alternative crypto backend

Browse Source 
This turns the `-Dgcrypt` build time option into a more generic
`-Dcrypto` option, which enables user to choose which cryptographic
library to link with.  It currently supports libgcrypt (`libgcrypt`)
and GnuTLS (`gnutls`); for the latter, GnuTLS 3.8.2 is the minimum
required version.
