* Patched crt0 to support a pre_main
* pre_main sets up environment variables, can do other things later,
but then just jumps to main with the same arguments.
* Updated a bunch of apps to pass environment variables around.
- libc functions not implemented yet
- see `env` for an example of reading variables
- see `esh` for an example of how to set and maintain variables for
sending to other applications
Both of the above will be the basis for the libc implementation.
* Finally bring syscall.h up to speed and include all syscalls in the
syscall module of the C library.
* Remove the third-party obfuscated C demos (we have nyancat, good
enough)
* Fix userspace apps to build without complaining about undeclared
strtok_r by disable __STRICT_ANSI__
* Fix .eh_frame by including the proper stuff with libgcc.
[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))
