Non-SUS functions

[Shaun Jackman]

Busybox uses the following non-SUS functions, which are not provided by newlib.

	daemon getpagesize klogctl mkdtemp mount pivot_root reboot
	stime swapoff swapon sysinfo umount

Most of these functions are irreplaceable, but can anyone suggest SUS
functions that could be used in lieu of these? Which of these
functions, if any, should be added to newlib?

Newlib is also missing the two SUS functions getgrnam and getgrgid.
Could a free implementation of these functions be incorporated into
newlib?

Cheers!
Shaun
