[GIT PULL] Miscellaneous keyrings and modsign fixes

[David Howells <dhowells@redhat.com>]

Hi James,

Can you pass these changes on to Linus?  There are four:

 (1) Fix a potential race between keyring destruction and keyring lookup by
     name.

 (2) Remove unneeded headers from extract-cert.c, at least one of which will
     prevent it from compiling if the openssl libs are too old.

 (3) Don't strip leading zeros from the key ID when using it to construct a
     key description lest this make the key not match.

 (4) Downgrade use of CMS-based signatures to PKCS#7-based signatures if the
     openssl libs are too old.  Note that in this case, you are also limited
     to using SHA1 as the pre-1.0.0 openssl libs don't support anything else.

Thanks,
David
