Build outgoing SSH agent requests in a strbuf.

Browse Source 
This simplifies the client code both in ssh.c and in the client side
of Pageant.

I've cheated a tiny bit by preparing agent requests in a strbuf that
has space reserved at the front for the packet frame, which makes life
easier for the code that sends them off.
