Kernel: Don't symbolicate symbol+offset for obvious non-kernel addresses.

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.

Kernel: VFS::open/create should take base Inode& instead of InodeIdentifier.

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.
