Subject: [PATCH] _libssh2_recv(): handle ENOENT error as EAGAIN

A sftp session failed with error "failure establishing ssh session" on
Solaris and HP-UX. Sometimes the first recv() function call sets errno
to ENOENT. In the man pages for recv of Solaris and HP-UX the error
ENOENT is not documented.

I tested Solaris SPARC and x86, HP-UX i64, AIX, Windows and Linux.
