2479ead718 Everywhere: Remove unnecessary clang-format offs
Mostly due to the fact that clang-format allows aligned comments via
AlignTrailingComments.

We could also use raw string literals in inline asm, which clang-format
deals with properly (and would be nicer in a lot of places).

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.

2b2828ae52 Kernel: Slap UNMAP_AFTER_INIT on a bunch more functions
We're now able to unmap 100 KiB of kernel text after init. :^)

bbe787a0af Everywhere: Re-format with clang-format-11
Compared to version 10 this fixes a bunch of formatting issues, mostly
around structs/classes with attributes like [[gnu::packed]], and
incorrect insertion of spaces in parameter types ("T &"/"T &&").
I also removed a bunch of // clang-format off/on and FIXME comments that
are no longer relevant - on the other hand it tried to destroy a couple of
neatly formatted comments, so I had to add some as well.

21d5f4ada1 Kernel: Absorb LibBareMetal back into the kernel
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.

0b7fc525e1 Interrupts: Simplify IRQ disabling & enabling in IRQController(s)
Instead of blindly setting masks, if we want to disable an IRQ and it's
already masked, we just return. The same happens if we want to enable an
IRQ and it's unmasked.

cb676f1211 Interrupts: Do a specific EOI when using the PIC
Before this change, we did a non-specific EOI, which could lead to
problems with other IRQs that are handled in the PIC. Since the original
8259A datasheet permits such functionality and we are not losing any
functionality, this change is acceptable even though we don't experience
problems with the EOI currently.

f86be46c98 Kernel: Abstract IRQ controller handling from Interrupt handlers
Now we don't send raw numbers, but we let the IRQController object to
figure out the correct IRQ number.
This helps in a situation when we have 2 or more IOAPICs, so if IOAPIC
1 is assigned for IRQs 0-23 and IOAPIC 2 is assigned for IRQs 24-47,
if an IRQHandler of IRQ 25 invokes disable() for example, it will call
his responsible IRQController (IOAPIC 2), and the IRQController will
subtract the IRQ number with his assigned offset, and the result is that
the second redirection entry in IOAPIC 2 will be masked.

0fc60e41dd Kernel: Use klog() instead of kprintf()
Also, duplicate data in dbg() and klog() calls were removed.
In addition, leakage of virtual address to kernel log is prevented.
This is done by replacing kprintf() calls to dbg() calls with the
leaked data instead.
Also, other kprintf() calls were replaced with klog().

7d59a67504 Kernel: Add the PIC class
This class inherits from IRQController class, and represents
the common Intel 8259 PIC chip.
