[init] Reenable freetype in the Terminal spawned from init
[nyancat] Fix timing and update animations
[esh] Fix bug with child pid collection and signal handling
This update includes support for shadow passwords, stored in
/etc/master.passwd, as well as support for an /etc/passwd file
containing user/uid/full name/shell associations, which are used by the
shell to get your username for display purposes, as well as by whoami
for the same reason. The login tool does not yet select the right shell
though this is planned.
* root's password is `toor` (a throwback to older times)
* local's password is `local` (because it's obvious)
Completely removes:
* The kernel terminal (both VGA and graphical)
* The kernel ANSI parser (obviously)
* kgets() function
* Dozens of other functions that were made useless
Adds:
* Userspace terminal that should work (relatively) well
* Keyboard device driver (implemented with a "pipe" object)
* Stabalized interrupt interface
* `clear` uses the c library
* All panic screens and kprintf() output goes to the serial line ONLY
* The kernel boots directly into /bin/terminal (no arguments, unless you
want to add them (such as -f))
