Kernel: Fail a bit more gracefully when we don't have userspace symbols.

Kernel: Symbolicate userspace backtraces using ELFLoader.
...
Stash away the ELFLoader used to load an executable in Process so we can use
it for symbolicating userspace addresses later on. This will make debugging
userspace programs a lot nicer. :^)

Kernel: Simplify dump_backtrace() API for clients.
...
It makes no sense that clients had to worry about whether or not KSyms
were loaded.

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: Make symbolication callable from kmalloc().
...
It wasn't possible to symbolicate from kmalloc(), since symbolication would
call kmalloc(). :^)

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. :^)

Use modern C++ attributes instead of __attribute__ voodoo.
...
This is quite nice, although I wish [[gnu::always_inline]] implied inline.
Also "gnu::" is kind of a wart, but whatcha gonna do.

It's now possible to create zero-length files! :^)
Also hook up the new functionality in /bin/touch.

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

Move kernel symbolication code out of init.cpp and into its own KSym files.
...
Also use a simple array of { dword, const char* } for the KSyms and put the
whole shebang in kmalloc_eternal() memory. This was a fugly source of
kmalloc perma-frag.
