* implement legacy compatibility in settings.h and configure.ac (adds --enable-blake2b while retaining --enable-blake2);
* fix incorrect Blake2 gates in wolfcrypt/src/hash.c wc_HashGetDigestSize() and wc_HashGetBlockSize();
* in wolfcrypt/test/test.c hash_test(), backfill missing Blake2 test coverage and separate blake2b from blake2s in typesHashBad[];
* in tests/api/test_hash.c, separate blake2b from blake2s in notCompiledHash[], sizeSupportedHash[], and sizeNotCompiledHash[].
which force on BUILDING_WOLFSSL and do boilerplate includes, and update library
sources to include them at the top.
wolfssl_sources.h includes types.h, error-crypt.h, and logging.h, and
conditionally, config.h. settings.h and wc_port.h are unconditionally
included at the top of types.h.
wolfssl_sources_asm.h includes settings.h, and conditionally, config.h.
Add wolfssl_sources*.h to wolfcrypt/src/include.am, and to several IDE/ project
files.
Also added a TEST_WOLFSSL_SOURCES_INCLUSION_SEQUENCE clause in
wolfssl/wolfcrypt/settings.h to allow coverage testing.
In wolfcrypt/src/misc.c, retain existing ad hoc boilerplate includes, and use
them if WOLFSSL_VIS_FOR_TESTS, otherwise include the new wolfssl_sources.h.
Define WOLFSSL_VIS_FOR_TESTS at top of wolfcrypt/test/test.c.
Also renamed WOLFSSL_NEED_LINUX_CURRENT to WOLFSSL_LINUXKM_NEED_LINUX_CURRENT,
for clarity.
