[oi-dev] glib changes review

[Alexander Pyhalov]

Please, review: 
https://github.com/OpenIndiana/oi-userland/compare/Openindiana:oi/hipster...pyhalov:pfexec

Issues: https://www.illumos.org/issues/6728
	https://www.illumos.org/issues/5633


The issue is that glib incorrectly detects pfexec usage as setuid 
program (even when pfexec doesn't change euid). So, it refuses to launch 
dbus - https://github.com/GNOME/glib/blob/master/gio/gdbusaddress.c#L1060

We heal it by falling back to euid/uid comparison. We also use pfexec to 
launch brasero and sound-juicer.
After 
https://github.com/OpenIndiana/oi-userland/commit/9f0f786ce02ff7a120952fa34888cdcca5b8469d 

console user (Console User) should have "Desktop Removable Media User" 
profile and have sys_devices privileges, necessary for brasero and sound 
juicer (which uses brasero libraries) to work with CD devices.

I'm a bit concerned about unexpected security issues which it could cause...
