wolfssl/ssl.h, wolfssl/error-ssl.h, wolfssl/wolfcrypt/error-crypt.h, wolfcrypt/src/error.c, and src/internal.c: * fix values of WOLFSSL_ERROR_SSL and WOLFSSL_ERROR_WANT_X509_LOOKUP to match OpenSSL values; * move legacy CyaSSL compat layer error codes from ssl.h to error-ssl.h and renumber them to conform to existing sequence; * move enum IOerrors from ssl.h to error-ssl.h to get picked up by support/gen-debug-trace-error-codes.sh; * add to enum wolfSSL_ErrorCodes negative counterparts for several positive error return constants; * include error-ssl.h from ssl.h; * add label (wolfCrypt_ErrorCodes) to error-crypt.h enum, and in wc_GetErrorString(), use switch ((enum wolfCrypt_ErrorCodes)error) to activate switch warnings for missing enums; * in wolfSSL_ERR_reason_error_string(), use switch((enum wolfSSL_ErrorCodes)error) to activate switch warnings for missing enums; * in ssl.h, add special-case WOLFSSL_DEBUG_TRACE_ERROR_CODES macros for WOLFSSL_FAILURE; * in error-crypt.h, add missing WOLFSSL_API attribute to wc_backtrace_render(); and * harmonize gating of error codes, ssl.h / error-ssl.h / internal.c:wolfSSL_ERR_reason_error_string() / api.c:error_test(). tests/api.c: * add error_test() adapted from wolfcrypt/test/test.c, checking all error strings for expected presence/absence and length, called from existing test_wolfSSL_ERR_strings(). * in post_auth_version_client_cb(), add missing !NO_ERROR_STRINGS gating. add numerous WC_NO_ERR_TRACE()s to operand error code uses, cleaning up error traces in general, and particularly when WOLFSSL_DEBUG_TRACE_ERROR_CODES_ALWAYS. * crypto lib (36), * crypto test&benchmark (20), * TLS lib (179), * examples (122), * linuxkm (3), * tests/api.c (2272).
