1682f0b760 Everything: Move to SPDX license identifiers in all files.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

14f6425b8f LibC: Add pwrite(..) implementation to match the existing pread(..)
Add a basic non-thread safe implementation of pwrite, following the
existing pread(..) design.

This is needed for https://fio.readthedocs.io

According to POSIX.1-2001 the return type should be unsigned int.

c91bb72964 LibC: Add vfork() as a simple wrapper around fork()
I don't know if we should implement optimized vfork(). I'm adding it
here since SDL2 uses it.

5d180d1f99 Everywhere: Rename ASSERT => VERIFY
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.

bb777459a0 LibC+LibPthread: Implement pthread_atfork()
This required a bit of rearchitecture, as pthread_atfork() required a
mutex, and duplicating a mutex impl for it was silly.
As such, this patch moves some standalone bits of pthread into LibC and
uses those to implement atfork().
It should be noted that for programs that don't use atfork(), this
mechanism only costs two atomic loads (as opposed to the normal mutex
lock+unlock) :^)

e87eac9273 Userland: Add LibSystem and funnel all syscalls through it
This achieves two things:

- Programs can now intentionally perform arbitrary syscalls by calling
  syscall(). This allows us to work on things like syscall fuzzing.

- It restricts the ability of userspace to make syscalls to a single
  4KB page of code. In order to call the kernel directly, an attacker
  must now locate this page and call through it.

b42f0b9650 LibC: Change a couple of ASSERT_NOT_REACHED() to TODO()
Just for semantic correctness and better visibility of those
unimplemented stub functions.

ea5825f2c9 Kernel+LibC: Make sys$getcwd truncate the result silently
This gives us the superpower of knowing the ideal buffer length if it fails.
