appropriate checks in tls1_check_chain.

the certificate can be used for (if anything). Set valid_flags field
in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
to have similar checks in it.

Add new "cert_flags" field to CERT structure and include a "strict mode".
This enforces some TLS certificate requirements (such as only permitting
certificate signature algorithms contained in the supported algorithms
extension) which some implementations ignore: this option should be used
with caution as it could cause interoperability issues.

Only store encoded versions of peer and configured signature algorithms.
Determine shared signature algorithms and cache the result along with NID
equivalents of each algorithm.

TLS v1.2. These are sent as an extension for clients and during a certificate
request for servers.

TODO: add support for shared signature algorithms, respect shared algorithms
when deciding which ciphersuites and certificates to permit.

Make partial chain chekcing work with EE certificates only.
Remove unneeded -trust_other option from tocsp.
(Backport from HEAD)

Support - as a file for standard input or output.

Add -badsig option to generate invalid signatures for testing.

New -rmd option to specify digest to sign OCSP responses with.

Add new verify options to set checks.

Don't verify our own responses.

modification to the OCSP helper purpose breaks normal OCSP verification. It is
no longer needed now we can trust partial chains.

store instead of the default which is to return an error if we can't build
the complete chain. [backport from HEAD]

Use -1 to check all extensions in CRLs.
Always set flag for freshest CRL.
