4lDO2 308c2cc711 Support modifying processes' sigactions.
This is, other than vfork, the last piece of functionality that the
previous clone() offered (CLONE_SIGHAND) which previously was not
implemented.

4lDO2 240d91f951 Set address space/files when closing, not writing.
This fixes file descriptor leaks. Suppose relibc is just about to set
the address space. For this, it needs to write the address space fd to
the selection fd. To avoid having to close them in the kernel, it rather
memorizes what the file descriptors refer to internally, and then do the
actual operation when they are gone, i.e. when closing.

4lDO2 b50495bfa5 WIP: Support clone in userspace
Everything seems to work for the most part, but now there are tons of
daemons which rely on syscall::clone, which is now implemented in relibc
:(

4lDO2 563121596d Fix running on multi_core.
Turns out the problem all along was that the ActivePageTable was never
dropped in usermode_bootstrap. So as soon as any other hardware thread
tried to do page table business, it deadlocked!
