Expose libssh2_trace function (#209)

* Expose libssh2_trace function and associated
constants, to allow enabling libssh2 trace
output.

* set LIBSSH2_WIN32 on windows build so that
gettimeofday replacement will be compiled.

* libssh2_trace actually returns int, even though
the documentation says it returns void. This
was causing systest to fail.
Changed the FFI to match the C function.
