LibC: implement fgetpos and fsetpos
...
They're just "front ends" for ftell and fseek, but they do their
job.
Fixes #913

LibC: Remove a leftover default_stream
...
Long ago, there was a fourth stdio default stream, stddbg, connected to the
debug console. It has since been replaced by the dbgputstr() and dbgputch()
syscalls.

LibC: Minor changes to make nasm work
...
* Added some missing macros to headers
* Stubbed strftime() time function to not assert
* Added "rt" mode to fopen(), working just like "r" or "rb"

LibC: Stop stdio from adding null terminators out of bounds ( #685 )
...
When using the bounded string operations (e.g. snprintf), the null
terminator was always being written even if there was no space for
it (or indeed any valid buffer at all)
This overwriting caused segmentation faults and memory corruption

LibC: Write to the dbg() every time we perror() in userspace
...
There's a high chance that we're interested in whatever errors come out
of perror(), so let's output those on the debugger as well.

LibC: In fgetc(), fread() will never return < 0.
...
Furthermore, fread() has already handled EOF, so there's no need to do
it again. If we read a character, return it, otherwise return EOF.
Note that EOF means "EOF or error" here.

Kernel+LibC: Add a dbgputstr() syscall for sending strings to debug output.

This is very handy for the DebugLogStream implementation, among others. :^)

Kernel+LibC: Add a dbgputch() syscall and use it for userspace dbgprintf().
...
The "stddbg" stream was a cute idea but we never ended up using it in
practice, so let's simplify this and implement userspace dbgprintf() on top
of a simple dbgputch() syscall instead.
This makes debugging LibC startup a little bit easier. :^)

Libraries: Create top level directory for libraries.

Things were getting a little crowded in the project root, so this patch
moves the Lib*/ directories into Libraries/.
