Peter Wu d7187e0b1b wsutil: Add Curve25519 ECDH (X25519) using Gcrypt 
The WireGuard dissector will need X25519 to enable decryption, add a
Gcrypt implementation that implements the NaCl/Sodium interface.

While inspired by the MPI example in t-cv25519.c, note subtle but
important correctness/interoperability fixes: add a check for infinity
(gcry_mpi_ec_get_affine) and handle short values from gcry_mpi_print.
The last issue is ugly, perhaps the high level API (gcry_pk_decrypt)
should be used instead (which < 2% slower than this MPI implementation).
(Both issues were found through fuzzing.)

As for alternative options, Sodium is superior but would be a new
dependency. For some older performance and usability notes (comparing
crypto_scalarmult_curve25519_base (note "_base") against others), see
https://lists.gnupg.org/pipermail/gcrypt-devel/2018-July/004532.html

Performance comparison on Ubuntu 18.04 (i7-3770) between Sodium 1.0.16
against Gcrypt 1.8.3 and Gcrypt 86e5e06a (git master, future 1.9.x) by
computing 65536 times X25519(1, 8) via crypto_scalarmult_curve25519:

    Sodium (sandy2x):   1.4x faster than ref10
    Sodium (ref10):     1 (baseline)
    Gcrypt (git):       5x slower than ref10, 7x slower than sandy2x
    Gcrypt (1.8.3):     17x ref10, 24x sandy2x (took 65 seconds)
