Start fixing things up to build with a proper cross-compiler.

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.

Add a fast memcpy() using MMX when we're moving >= 1KB.
...
This is a nice speedup for WindowServer. I'll eventually have to do this
with SSE but the kernel doesn't support SSE yet so this is it for now.

Kernel: Rewrite ProcFS.
...
Now the filesystem is generated on-the-fly instead of manually adding and
removing inodes as processes spawn and die.
The code is convoluted and bloated as I wrote it while sleepless. However,
it's still vastly better than the old ProcFS, so I'm committing it.
I also added /proc/PID/fd/N symlinks for each of a process's open fd's.

Let's do dword-at-a-time memcpy() and memset() in userspace as well.
...
Also fix a dumb bug that showed up when I was memsetting something other
than zeroes.

Don't use dword-by-dword memset/memcpy if the addresses are unaligned.
...
Also don't enable the large kmalloc catcher by default.

Make the kernel's memcpy() and memset() go fast with dword copies.
...
Also I learned that the ABI allows us to assume DF=0 on function entry.

Make the kernel's memset do a "rep stosb" because.

This is really neat. :^)

Make kernel build with clang.
...
It's a bit faster than g++ and seems to generate perfectly fine code.
The kernel is also roughly 10% smaller(!)

Also fixed broken strcpy that didn't copy the null terminator.

Import the "gerbert" kernel I worked on earlier this year.
...
It's a lot crappier than I remembered it. It's gonna need a lot of work.
