Subject: Rename the ssh credentials
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=70a8c78f3618d70cf6de0961e4e3884a003a1ff0;p=libgit2.git

Rename the ssh credentials

The names from libssh2 are somewhat obtuse for us. We can simplify the
usual key/passphrase credential's name, as well as make clearer what the
custom signature function is.
