1369aa9da9 Fix wrong datatypes to printf in ls. 
gcc still complains, but that is because uintmax_t is declared incorrectly.

c9eb1b2cb3 Better collection of zombie processes. 
Note that there seems to be a deadlock if a process exits when there are
zombies around. Init also doesn't handle zombie children correctly as there
is sent no SIGCHLD signal yet.

db79994e64 Refactored all the sortix headers into a include directory.

Jonas 'Sortie' Termansen
fdbd4ca90d Implemented large parts of the stdio(3), including fprintf. 
Made FILE an interface to various backends. This allows application writers
to override the standard FILE API functions with their own backends. This
is highly unportable - it'd be nice if a real standard existed for this.
glibc already does something like this internally, but AFAIK you can't hook
into it.

Added fdopen(3), fopen(3), fregister(3), funregister(3), fread(3),
fwrite(3), fseek(3), clearerr(3), ferror(3), feof(3), rewind(3), ftell(3),
fflush(3), fclose(3), fileno(3), fnewline(3), fcloseall(3), memset(3),
stdio(3), vfprintf(3), fprintf(3), and vprintf(3).

Added a file-descriptor backend to the FILE API.

fd's {0, 1, 2} are now initialized as stdin, stdout, and stderr when the
standard library initializes.

fcloseall(3) is now called on exit(3).

decl/intn_t_.h now @include(size_t.h) instead of declaring it itself.

Added <stdint.h>.

The following programs now flush stdout: cat(1), clear(1), editor(1),
init(1), mxsh(1).

printf(3) is now hooked up against vprintf(3), while Maxsi::PrintF
remains using the system call, for now.

2afe9d1fd6 Implemented the fork() system call and what it needed to work properly. 
This commit got completely out of control.

Added the fork(), getpid(), getppid(), sleep(), usleep() system calls, and
aliases in the Maxsi:: namespace.

Fixed a bug where zero-byte allocation would fail.

Worked on the DescriptorTable class which now works and can fork.

Got rid of some massive print-registers statements and replaced them with
the portable InterruptRegisters::LogRegisters() function.

Removed the SysExecuteOld function and replaced it with Process::Execute().

Rewrote the boot sequence in kernel.cpp such that it now loads the system
idle process 'idle' as PID 0, and the initization process 'init' as PID 1.

Rewrote the SIGINT hack.

Processes now maintain a family-tree structure and keep track of their
threads. PIDs are now allocated using a simple hack. Virtual memory
per-process can now be allocated using a simple hack. Processes can now be
forked. Fixed the Process::Execute function such that it now resets the
stack pointer to where the stack actually is - not just a magic value.
Removed the old and ugly Process::_endcodesection hack.

Rewrote the scheduler into a much cleaner and faster version. Debug code is
now moved to designated functions. The noop kernel-thread has been replaced
by a simple user-space infinite-loop program 'idle'.

The Thread class has been seperated from the Scheduler except in Scheduler-
related code. Thread::{Save,Load}Registers has been improved and has been
moved to $(CPU)/thread.cpp. Threads can now be forked. A new CreateThread
function creates threads properly and portably.

Added a MicrosecondsSinceBoot() function.

Fixed a crucial bug in MemoryManagement::Fork().

Added an 'idle' user-space program that is a noop infinite loop, which is
used by the scheduler when there is nothing to do.

Rewrote the 'init' program such that it now forks off a shell, instead of
becoming the shell.

Added the $$ (current PID) and $PPID (parent PPID) variables to the shell.
