The kernel no longer needs sprintf (which might, in theory, overflow),
so we can hide the C++ declaration and make the function uncallable
from within the kernel.
However, libstdc++ still links against it, as libstdc++ uses it for
demangling, from AK::demangle().

In contrast to sprintf, which might overflow the given buffer.
I feel bad about the code duplication, but that is a pre-existing issue.

Mostly -Wformat fixes, some of which pointed out real (if benign) bugs.

This was supposed to be the foundation for some kind of pre-kernel
environment, but nobody is working on it right now, so let's move
everything back into the kernel and remove all the confusion.

As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.

This just seems like something we should be able to do. The compiler
knows how long my "string literal" is, passing it along manually seems
siilly.

Let's simplify things. There is now only KERNEL.
To see if you're on Serenity, check if __serenity__ is defined.

Turns out we can use abi::__cxa_demangle() for this, and all we need to
provide is sprintf(), realloc() and free(), so this patch exposes them.
We now have fully demangled C++ backtraces :^)

serial_debug will output all the kprintf and dbgprintf data to COM1 at
8-N-1 57600 baud. this is particularly useful for debugging the boot
process on live hardware.
Note: it must be the first parameter in the boot cmdline.
|
|
This is very handy for the DebugLogStream implementation, among others. :^)

- "make" builds the normal Serenity libhtml.a
- "make -f Makefile.host" builds a test program for the host machine.

Also run it across the whole tree to get everything using the One True Style.
We don't yet run this in an automated fashion as it's a little slow, but
there is a snippet to do so in makeall.sh.
