manual:
- adding aggregate passing and returning info for x64 (win and sysv, however, *only* w/ respect to types supported by dyncall)
- python binding text cleanup and sync with current binding version
- added suite_aggrs description and cleaned up other test suite descriptions a bit
- update list of calling convention modes
- cleanup and minor other fixes (e.g. changed \newpage in many places to \clearpage to avoid hitting float limit, crlf->cr, ...)
