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, ...)

- add support for SELinux
- dyncall sparc v7/v8: -xO3 on SunPro segfaults in tests.
- dyncall sparc64 port: works fine on Debian 6, but has issues on OpenBSD and Solaris regarding passing of float and double values.
- this BUGS file should be merged with ToDo or vice-versa
