LibC: Make sure perror() is consistent about the errno it prints

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.

AK: Rename ValueRestorer => ScopedValueRollback.
...
Qt had a pretty good name for this concept, so let's steal it. :^)

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/.
