Publish libssh2-sys 0.3.0

[luqmana]

Hi, could a new release for libssh2-sys be published (0.3.0) to crates.io. Looks like upstream libssh2 changes were pulled in that fix a number of issues (specifically getting the sha2 signature algorithm support).

Can confirm that pointing git2-rs at current master works to fetch from github with an rsa key whereas the latest version on crates.io (0.2.23) doesn't.

Sadly I can't actually publish libssh2-sys so I will need to pass the buck on this one. That said, I agree that we should make another release of libssh2-sys.

Would be possible to also publish a version that is compatible with the ssh2-rs used by cargo? I'm having lots of annoying problems due openwrt providing a too new libressl and a too stale glibc.

ssh2 0.9.4 and libssh2-sys 0.3.0 have both been published.
