Factor out get_rsa_ssh1_priv_agent from Pageant.

Browse Source 
The code that reads an SSH1_AGENTC_ADD_RSA_IDENTITY message and parses
an RSA private key out of it now does it by calling a BinarySource
function in sshrsa.c, instead of doing inline in the Pageant message
handler. This has no functional change, except that now I can expose
that separate function in the testcrypt API, where it provides me with
a mechanism for creating a bare RSAKey structure for purposes of
testing RSA key exchange.
