gc: support HMAC-SHA256 and HMAC-SHA512.
* lib/gc.h: Add gc_hmac_sha256 and gc_hmac_sha512.
* lib/gc-libgcrypt.c (gc_hmac_sha256, gc_hmac_sha512): New
functions.
(gc_hmac_md5): Use symbolic constant.
* lib/gc-gnulib.c: Include hmac.h for HMAC-SHA256/512 too.
(gc_hmac_sha256, gc_hmac_sha512): New functions.
* lib/hmac.h: Add hmac_sha256 and hmac_sha512 prototypes.
* m4/sha256.m4: Protect against empty expansion.
