Support GnuTLS as an alternative crypto backend
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.
