sched/signal/sig_nanosleep.c and libc/time/lib_nanosleep.c: Implement clock_nanosleep(). nanosleep() is now reduced to a libc wrapper around clock_nanosleep().

Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep().
...
Squashed commit of the following:
Change all calls to usleep() in the OS proper to calls to nxsig_usleep()
sched/signal: Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable.
sched/signal: Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.

The libc versions of get/sethostname should just call the internal net/netdb versions in the flat build. In the protected and kernel builds, sethostname is a system call but gethostname calls uname() to get the hostname

From Lorenz Meier: The implementation of access() as vararg macro has the issue that any function call with the same name (even in a C++ class) will match with it and result in a compile error. I have replaced it with a small function, and tried to have decent documentation as well. This resolves the compile issue, and shouldn’t have negative side effects for users of the function.

execv() is a basic system interface. It should not be in libc/ but rather in sched/task. Its symboltable helper logic also belongs in the kernel but belings in binfmt/ with the other symbol table logic
