Add support for public key input and output in rsa and dsa utilities with some

new DSA public key functions that were missing.

Also beginning of a cache for X509_EXTENSION structures: this will allow them
to be accessed more quickly for things like certificate chain verification...

Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
*) Add -pubin and -pubout options to the rsa and dsa commands. These allow
a public key to be input or output. For example:
openssl rsa -in key.pem -pubout -out pubkey.pem
Also added necessary DSA public key functions to handle this.
[Steve Henson]
*) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
in the message. This was handled by allowing
X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
