It's now possible to load a .o file into the kernel via a syscall.
The kernel will perform all the necessary ELF relocations, and then
call the "module_init" symbol in the loaded module.
This is an implementation of syslog with some OpenBSD extensions.
There is no syslogd support (so it only logs to dbgprintf/stderr),
but otherwise is functional.
Many weird defines are always present, because some syslog users in
the wild check for their existence.
These are basically copy and pasted from the regular string version.
Also add some more multi-byte/wide conversion stub.
libarchive wanted these. There's a lot more, but we can add them
one at a time.
We had some kernel-specific gizmos in AK that should really just be in the
Kernel subdirectory instead. The only thing remaining after moving those
was mmx_memcpy() which I moved to the ARCH(i386)-specific section of
LibC/string.cpp.
