When parsing a certificate with the basic constraints extension the max_pathlen that was read from it was incremented regardless of its value. However, if the max_pathlen is equal to INT_MAX (which is highly unlikely), an undefined behaviour would occur. This commit adds a check to ensure that such value is not accepted as valid. Relevant tests for INT_MAX and INT_MAX-1 are also introduced. Certificates added in this commit were generated using the test_suite_x509write, function test_x509_crt_check. Input data taken from the "Certificate write check Server1 SHA1" test case, so the generated files are like the "server1.crt", but with the "is_ca" field set to 1 and max_pathlen as described by the file name.
