Make lots more algorithm structures globally visible.

Browse Source 
Previously, lots of individual ssh2_cipheralg structures were declared
static, and only available to the rest of the code via a smaller
number of 'ssh2_ciphers' objects that wrapped them into lists. But I'm
going to want to access individual ciphers directly in the testing
system I'm currently working on, so I'm giving all those objects
external linkage and declaring them in ssh.h.

Also, I've made up an entirely new one, namely exposing MD5 as an
instance of the general ssh_hashalg abstraction, which it has no need
to be for the purposes of actually using it in SSH. But, again, this
will let me treat it the same as all the other hashes in the test
system.

No functional change, for the moment.
