* Speed improvements
* Crash fixers
* Significant overhaul to escape handling based on extensive use of the
new serial console and a remote connection to a Linux box.
* Updated included terminfo file to accurately reflect terminal
behavior.
Some fun facts:
* vim runs great on a remote console (though the serial line slows a lot
of things down, it still runs rather smoothly)
* going to fix GNU screen, maybe in next commit, dunno
* tested with htop, less, and a bunch of other stuff
* fix some terminal bugs (some, not all)
* add a serial device to the VFS
* fix up serial so it works better
* add a serial-console application
* fix a bug in some other stuff relating to allocations
* change size of the terminal described by toaru.terminfo
* adds a new system call
