Initially the libssh2 code was indented with tabs of 4 spaces. Some of

the recent commits converted the tabs to 4 spaces, which matched the
initial indent size.  Other commits converted the tabs to 8 spaces, this
didn't match.

All the code has been converted to 4 space indents.  No changes to line
lengths or actual code was performed.  This is in preperation to my up
coming non-blocking work so my commits should only be code changes and
line lengths in the code I am working on.
