96db775ac1 LibC: Add setenv().
If I'm understanding the standard C library correctly, setenv() copies while
putenv() does not. That's really confusing and putenv() basically sucks.
To know which environment variables to free on replacement and which ones to
leave alone, we keep track of the ones malloced by setenv in a side table.

This patch also moves Shell to using setenv() instead of putenv().

Fixes #29.

9cd0f6ffac Kernel/LibC: Implement sched_* functionality to set/get process priority
Right now, we allow anything inside a user to raise or lower any other process's
priority. This feels simple enough to me. Linux disallows raising, but
that's annoying in practice.

b160677e9e LibC: Add malloc_size() to tell you how big an allocation might be.
It can't be 100% precise but it doesn't really matter. Use this to implement
realloc() nicely. This also fixes a bug in realloc() where we didn't take
the size of the allocation metadata into account when computing the size of
an allocation backed by a BigAllocationBlock.

6785250f8c LibC: realloc() should reuse the existing allocation more often.
We were only reusing the existing allocation if the new requested size
was exactly the same as the fudged size of the block. This meant that
realloc() could allocate a new block even though the new block would be
identical to the old block.

c1f8df5f86 LibC: Don't define ALWAYS_INLINE if it's already defined.
This makes building GCC a bit quieter.

0dc9af5f7e Add clang-format file
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.

ae470ec955 Kernel: Add getpeername() syscall, and fix getsockname() behavior.
We were copying the raw IPv4 addresses into the wrong part of sockaddr_in,
and we didn't set sa_family or sa_port.

b3a1671f1a Kernel: Add support for recv() with MSG_DONTWAIT.
Passing this flag to recv() temporarily puts the file descriptor into
non-blocking mode.

Also implement LocalSocket::recv() as a simple forwarding to read().

we control, e.g malloc() and GraphicsBitmap.

This means that it's no longer incorrectly linked into LibC and Kernel.

b2dd12daac LibC: Change putenv (and getenv) to not copy, but directly return the environ values.
This is in keeping with how putenv should function. It does mean that
the shell's export command now leaks, but that's not a difficult fix.

Contributes to #29.

3cba2a8a78 Kernel: Add a beep() syscall that beeps the PC speaker.
Hook this up in Terminal so that the '\a' character generates a beep.
Finally emit an '\a' character in the shell line editing code when
backspacing at the start of the line.

This patch makes us recycle up to 8 blocks of 4KB size. This should
probably be extended to handle other sizes.

system() will now fork off a child process and execute the command via
/bin/sh -c. There are probably some things to fix here, but it's a start.
