_libssh2_transport_send: replaces _libssh2_transport_write

Browse Source 
The new function takes two data areas, combines them and sends them as a
single SSH packet. This allows several functions to allocate and copy
less data.

I also found and fixed a mixed up use of the compression function
arguments that I introduced in my rewrite in a recent commit.
