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.

This wraps gcry_mpi_t usage in the API with opaque strucs, so it would
be easier to port egg-dh to other crypto libraries.

Apart from having more developer-friendly messages if the assertions go
wrong, it also prevents the assertions not being run if
`G_DISABLE_ASSERT` is defined (e.g. for performance reasons).
Allow parallel building and testing by using a single Makefile.am
Implement parallel testing using TAP, with various drivers and
compilers living in the build/ directory.
Fix all sorts of issues that this caused, including builddir != srcdir,
leaks in tests and so on.
It would have been nice to break out all the above into separate
commits ... blush.
