wolfSSL_BIO_write rejected negative lengths but allowed a large positive
length through to wolfSSL_BIO_MEMORY_write. On a fresh buffer an INT_MAX
length overflowed the 4/3 buffer growth calculation, so the grow reported
success with a short allocation and the following copy read far past the
small source buffer.
Add an upper bound check that rejects lengths large enough to overflow the
growth math before any allocation or copy, and add a regression test that
drives a huge length through the public BIO_write entry point.
- Route BIO_ctrl_pending, BIO_reset, and BIO_get_mem_data through the custom method's ctrlCb when set, enabling fully custom BIO types to handle these operations.
- Add test_wolfSSL_BIO_custom_method that exercises a custom BIO with all callbacks (create, destroy, read, write, puts, gets, ctrl) and verifies each callback is invoked via bitfield tracking.
EVP into test_evp_cipher, test_evp_digest, test_evp_pkey and test_evp.
OBJ into test_ossl_obj.
OpenSSL RAND into test_ossl_rand.
OpenSSL PKCS7 and PKCS12 tests into test_ossl_p7p12.
CertificateManager into test_certman.
Move some BIO tests from api.c into test_evp_bio.c.
Fix line lengths.
