This patch adds the `USING_AK_GLOBALLY` macro which is enabled by
default, but can be overridden by build flags.
This is a step towards integrating Jakt and AK types.

Both my approach and the previous approach were wrong for different
cases. I've changed the Iterators index from storage-relative to
queue-relative, and it's much simpler and more obviously correct.
fixes #10383

Previously end() was only correct when m_head == 0.

Default implementations allow for more optimizations.

(...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.

Problem:
- Using regular functions rather than function templates results in
the arguments not being deduced. This then requires the same
function to be written multiple times and for `move` to be used
rather than `forward`.
Solution:
- Collapse multiple function overloads to a single function template
with a deduced argument. This allows the argument to be a forwarding
reference and bind to either an l-value or r-value and forward the
value.

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.

Previously we would not run destructors for items in a CircularQueue,
which would lead to memory leaks.
This patch fixes that, and also adds a basic unit test for the class.
|
|
This class inherits from CircularQueue and adds the ability dequeue
from the end of the queue using dequeue_end().
Note that I had to make some of CircularQueue's fields protected to
properly implement dequeue_end.
|
|
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.

This makes it a lot less finicky to make rapid moves like staircasing and
sudden turns.
|
|
|
|
This avoids blocking the main thread on filesystem access, which created
noticeable stutters during compilation.
|
|
|
|
This is pretty cute and helps me spot when something's chewing up CPU.
|
|
Also add a /bin/dmesg program for convenience.

It's now possible to do this in bash:
cat kernel.map | fgrep List
This is very cool! :^)

- Turn Keyboard into a CharacterDevice (85,1) at /dev/keyboard.
- Implement MM::unmapRegionsForTask() and MM::unmapRegion()
- Save SS correctly on interrupt.
- Add a simple Spawn syscall for launching another process.
- Move a bunch of IO syscall debug output behind DEBUG_IO.
- Have ASSERT do a "cli" immediately when failing.
This makes the output look proper every time.
- Implement a bunch of syscalls in LibC.
- Add a simple shell ("sh"). All it can do now is read a line
of text from /dev/keyboard and then try launching the specified
executable by calling spawn().
There are definitely bugs in here, but we're moving on forward.
