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. * m4/sha512.m4: Likewise. * lib/hmac-sha256.c: New file. * lib/hmac-sha512.c: Likewise. * m4/gc-hmac-sha256.m4: Likewise. * m4/gc-hmac-sha512.m4: Likewise. * m4/gc-sha256.m4: Likewise. * m4/gc-sha512.m4: Likewise. * modules/crypto/gc-hmac-sha256: Likewise. * modules/crypto/gc-hmac-sha256-tests: Likewise. * modules/crypto/gc-hmac-sha512: Likewise. * modules/crypto/gc-hmac-sha512-tests: Likewise. * modules/crypto/hmac-sha256: Likewise. * modules/crypto/hmac-sha256-tests: Likewise. * modules/crypto/hmac-sha512: Likewise. * modules/crypto/hmac-sha512-tests: Likewise. * tests/test-gc-hmac-sha256.c: Likewise. * tests/test-gc-hmac-sha512.c: Likewise * tests/test-hmac-sha256.c: Likewise. * tests/test-hmac-sha512.c: Likewise
