Add test case for SCRYPT and rework the code.
* tests/t-kdf.c (check_scrypt): New.
(main): Call new test.
* configure.ac: Support disabling of the scrypt algorithm. Make KDF
enabling similar to the other algorithm classes. Disable scrypt if we
don't have a 64 bit type.
* cipher/memxor.c, cipher/memxor.h: Remove.
* cipher/scrypt.h: Remove.
* cipher/kdf-internal.h: New.
* cipher/Makefile.am: Remove files. Add new file. Move scrypt.c to
EXTRA_libcipher_la_SOURCES.
(GCRYPT_MODULES): Add GCRYPT_KDFS.
* src/gcrypt.h.in (GCRY_KDF_SCRYPT): Change value.
* cipher/kdf.c (pkdf2): Rename to _gcry_kdf_pkdf2.
(_gcry_kdf_pkdf2): Don't bail out for SALTLEN==0.
(gcry_kdf_derive): Allow for a passwordlen of zero for scrypt. Check
for SALTLEN > 0 for GCRY_KDF_PBKDF2. Pass algo to _gcry_kdf_scrypt.
(gcry_kdf_derive) [!USE_SCRYPT]: Return an error.
* cipher/scrypt.c: Replace memxor.h by bufhelp.h. Replace scrypt.h by
kdf-internal.h. Enable code only if HAVE_U64_TYPEDEF is defined.
Replace C99 types uint64_t, uint32_t, and uint8_t by libgcrypt types.
(_SALSA20_INPUT_LENGTH): Remove underscore from identifier.
(_scryptBlockMix): Replace memxor by buf_xor.
(_gcry_kdf_scrypt): Use gcry_malloc and gcry_free. Check for integer
overflow. Add hack to support blocksize of 1 for tests. Return
errors from calls to _gcry_kdf_pkdf2.
* cipher/kdf.c (openpgp_s2k): Make static.

This patch prepares the addition of more KDF functions, brings the
code into Libgcrypt shape, adds a test case and makes the code more
robust. For example, scrypt would have fail silently if Libgcrypt was
not build with SHA256 support. Also fixed symbol naming for systems
without a visibility support.
