[reSIProcate] setuid

[Ryan Kereliuk]

One feature I'd like to add to repro is the ability to run as some
specified user (e.g. repro --user username --group groupname) plus
the ability to chroot(2) into a jail (e.g. repro --chroot dir).
I'm doing this already with a repro wrapper but it would be nice to
build right in.  I think this is a Really good idea as we run beta code
on internet-attached hosts.

My question, and the reason I sent this to resiprocate-devel, is what this
means in a multiplatform scenario.  My guess is that none of this maps to
WIN32 whatsoever and that the remaining platforms will fall in line with
the right includes and typedefs.  Should I encapsulate the setuid/setgid
stuff in rutil as resip::ProcessUser with lots of #ifndef WIN32?

Followups to resiprocate-devel please!

Thanks,
