Kernel: Demangle userspace ELF symbols in backtraces
...
Turns out we can use abi::__cxa_demangle() for this, and all we need to
provide is sprintf(), realloc() and free(), so this patch exposes them.
We now have fully demangled C++ backtraces :^)

Kernel: Prevent kprintf() from asserting in Console::the() ( #718 )
...
This triggered a stack overflow because ubsan can call kprintf() at any
time, even before Console is initialized.

Kernel: Add serial_debug cmdline parameter
...
serial_debug will output all the kprintf and dbgprintf data to COM1 at
8-N-1 57600 baud. this is particularly useful for debugging the boot
process on live hardware.
Note: it must be the first parameter in the boot cmdline.

Kernel+LibC: Add a dbgputstr() syscall for sending strings to debug output.
...
This is very handy for the DebugLogStream implementation, among others. :^)

Kernel: Colorize debugger output from the kernel.
...
This makes it easy to distinguish kernel/userspace dbgprintf()'s. :^)

Kernel: Have File virtuals take a FileDescriptor& rather than a Process&.
...
This will allow us to implement different behaviors depending on the role
of the descriptor a File is being accessed through.

Kernel: Introduce threads, and refactor everything in support of it.
...
The scheduler now operates on threads, rather than on processes.
Each process has a main thread, and can have any number of additional
threads. The process exits when the main thread exits.
This patch doesn't actually spawn any additional threads, it merely
does all the plumbing needed to make it possible. :^)

Kernel: Get rid of Unix namespace.
...
This is no longer needed as the Kernel can stand on its own legs now
and there won't be any conflict with host system data types.

Pass the process to CharacterDevice::read/write.
...
This is much nicer than grabbing directly at 'current' inside a read().

Fix broken SpinLock.
...
The SpinLock was all backwards and didn't actually work. Fixing it exposed
how wrong most of the locking here is.
I need to come up with a better granularity here.

Add some basic field width support to printf().
...
Use it to make "ls" output a bit better. Also sys$spawn now fails with EACCES
if the path is not a file that's executable by the current uid/gid.

Add gettimeofday() syscall and LibC wrappers gettimeofday() and time().

This only has second accuracy right now, I'll work out subseconds later.

Move kprintf to its own file. It has nothing to do with VGA anymore.
