As of https://boringssl-review.googlesource.com/#/c/6980/, almost all of BoringSSL #ifdefs in cURL should be unnecessary: - BoringSSL provides no-op stubs for compatibility which replaces most #ifdefs. - DES_set_odd_parity has been in BoringSSL for nearly a year now. Remove the compatibility codepath. - With a small tweak to an extend_key_56_to_64 call, the NTLM code builds fine. - Switch OCSP-related #ifdefs to the more generally useful OPENSSL_NO_OCSP. The only #ifdefs which remain are Curl_ossl_version and the #undefs to work around OpenSSL and wincrypt.h name conflicts. (BoringSSL leaves that to the consumer. The in-header workaround makes things sensitive to include order.) This change errs on the side of removing conditionals despite many of the restored codepaths being no-ops. (BoringSSL generally adds no-op compatibility stubs when possible. OPENSSL_VERSION_NUMBER #ifdefs are bad enough!) Closes #640

/*
|
|
* Curl_des_set_odd_parity()
|
|
*
|
|
* This is used to apply odd parity to the given byte array. It is typically
|
|
* used by when a cryptography engines doesn't have it's own version.
|
|
*
|
|
* The function is a port of the Java based oddParity() function over at:
|
|
*
|
|
* http://davenport.sourceforge.net/ntlm.html
|
|
*
|
|
* Parameters:
|
|
*
|
|
* bytes [in/out] - The data whose parity bits are to be adjusted for
|
|
* odd parity.
|
|
* len [out] - The length of the data.
