[Libreoffice] [PUSHED] Some OSL cleanup

[Arnaud Versini]

Thanks,

For getpid, this is my mistake, sorry, I must check before if NPTL getpid
is conform to the posix requirements (one PID for all threads in one
process). It seems to be Posix compliant :

http://linux.die.net/man/7/pthreads

I will check and send you a patch for this.

I want to add some annotations like format_arg and noreturn (or an
equivalent for MSVC, CLang...)  specially for trace, assert, abort and
info. Is it useful ?

Best regards
