Call libssh2_error for every knownhost API failure.

Browse Source 
The libssh2 API calls should set the last error code and a message when
returning a failure by calling libssh2_error.  This changeset adds these
calls to the libssh2_knownhost_* API as well as libssh2_base64_decode.

This change also makes libssh2_error into a function rather than a macro.
Its implementation is moved to misc.c.  This function returns the error
code passed to it allowing callers to return the error value directly
without duplicating the error code.
