87c8120b95 Refactored libmaxsi/string.cpp into multiple files. 
However, parts libmaxsi/string.cpp remains as the kernel and parts of the
standard library still rely on <libmaxsi/string.h>.

01df97080e Refactored libmaxsi/io.cpp into multiple files. 
This creates more object files in the static library which reduces the size
of statically linked files as only the relevant object files are included.
In my experience, it reduced the size of the system initrd from 1.9 MiB to
1.6 MiB which is valuable.

12326f2e34 Added $LINES and $COLUMNS to the shell. 
This tests the fancy new system call tcgetwinsize(2).

143120d160 Added tcgetwinsize(2) for determining terminal resolution. 
Unfortunately this area is not standardized by POSIX. Linux uses an ioctl
which is not that bad, but I'd like to have a designated function. I'm not
sure if this facility is powerful enough and whether it should be improved.
Also note that I use a struct winsize as on Linux, but I use size_ts instead
for the heck of it. Perhaps I should use another name for the struct.

1761db9f27 Updated copyright format in unistd.h.

f5c4b64aff The console can now be rendered to any text buffer. 
The console renderer now renders to a text buffer, which can be implemented
on any device, whether it's the VGA text buffer or a bitmap graphics device
with font rendering. This replaces the older code that could only render to
a VGA framebuffer and where the input parsing was tightly coupled with the
device rendering phase.

b2814db927 Added support for getting a copy of the VGA Font. 
This will be useful for providing a text-mode like environment (console)
after having switched to graphical mode where the system needs a font.

22990b77b8 Refactored the internal kernel memory management API. 
It is now permission-oriented, not just user/kernel oriented.

Added <sys/mman.h> with nice PROT_{READ,WRITE,EXEC,FORK} constants.

c39473157a Implemented a new initrd format with better inode support. 
This enables useful features such as directories, CRC32 checksums, and other
useful features. The initrdfs in the kernel is now hooked up against the new
API, although the kernel's current limited FS support is a problem for now.
To work around that, directories are not supported at runtime, although the
internal API understands them wonderfully. This will be fixed when the
kernel gets a real VFS.
