By using non-DER or invalid encodings outside the signed portion of a
certificate the fingerprint can be changed without breaking the signature.
Although no details of the signed portion of the certificate can be changed
this can cause problems with some applications: e.g. those using the
certificate fingerprint for blacklists.
1. Reject signatures with non zero unused bits.
If the BIT STRING containing the signature has non zero unused bits reject
the signature. All current signature algorithms require zero unused bits.
2. Check certificate algorithm consistency.
Check the AlgorithmIdentifier inside TBS matches the one in the
certificate signature. NB: this will result in signature failure
errors for some broken certificates.
3. Check DSA/ECDSA signatures use DER.
Reencode DSA/ECDSA signatures and compare with the original received
signature. Return an error if there is a mismatch.
This will reject various cases including garbage after signature
(thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS
program for discovering this case) and use of BER or invalid ASN.1 INTEGERs
(negative or with leading zeroes).

This facilitates "universal" builds, ones that target multiple
architectures, e.g. ARMv5 through ARMv7. See commentary in

Also introduce OPENSSL_USE_DEPRECATED. If OPENSSL_NO_DEPRECATED is
defined at config stage then OPENSSL_USE_DEPRECATED has no effect -
deprecated functions are not available.
If OPENSSL_NO_DEPRECATED is not defined at config stage then
applications must define OPENSSL_USE_DEPRECATED in order to access

Also introduce compiler warnings for gcc for applications using

Causes more problems than it fixes: even though error codes
are not part of the stable API, several users rely on the
specific error code, and the change breaks them. Conversely,
we don't have any concrete use-cases for constant-time behaviour here.

Doing 'config ; make clean' broke because clean removed
header files that normal build didn't create. So don't

Some Makefiles had actions for "dclean" that really belonged
to the "clean" target. This is wrong because clean ends up,
well, not really cleaning everything.
