Adds/extends tests/api MC/DC DecisionCoverage + FeatureCoverage and tests/unit-mcdc white-box supplements for the remaining wolfCrypt primitives (first-pass per-module union; gap-closing to follow): - classic bigint: tfm.c, integer.c (extend test_wolfmath.c; tfm/integer whiteboxes) - coding.c, error.c, wc_encrypt.c, pwdbased.c - ed448.c + curve448.c (shared fe_448/ge_448 backends; ed448 whitebox) - random.c deepened + new wolfentropy.c (MemUse SP800-90B), whiteboxes - hash.c, kdf.c, signature.c, chacha20_poly1305.c - LMS/XMSS (wc_lms*.c, wc_xmss*.c) with impl whiteboxes - ML-KEM (wc_mlkem*.c), ML-DSA (wc_mldsa.c), SLH-DSA (wc_slhdsa.c) with whiteboxes New tests register in tests/api.c + tests/api/include.am. Frozen-module guards (!HAVE_SELFTEST && !HAVE_FIPS) applied to new random.c/pwdbased.c tests that call post-v4.1.0 symbols.

/*
|
|
* MC/DC / decision coverage for wolfcrypt/src/error.c (wc_GetErrorString /
|
|
* wc_ErrorString). error.c is a single large switch mapping every
|
|
* wolfCrypt_ErrorCodes value to its string; decision coverage means taking
|
|
* each case arm plus the default (unknown) arm. We sweep the whole error-code
|
|
* numeric span (span 1: -97..-299, span 2: -1000..-1019) so every case is
|
|
* taken, and also feed values outside every span so the default arm is taken.
|
|
*
|
|
* When NO_ERROR_STRINGS is defined the two symbols collapse to macros that
|
|
* return / copy a fixed "no support" string; the same calls still compile and
|
|
* return non-NULL, so this test is valid in both configurations (that is the
|
|
* NO_ERROR_STRINGS compiled-out path the coding-standard asks us to exercise).
