6a00e338a8 Make it possible to overwrite debug macros locally.
Leaking macros across headers is a terrible thing, but I can't think of
a better way of achieving this.

  - We need some way of modifying debug macros from CMake to implement
    ENABLE_ALL_THE_DEBUG_MACROS.

  - We need some way of modifying debug macros in specific source files
    because otherwise we need to rebuild too many files.

This was done using the following script:

    sed -i -E 's/#cmakedefine01 ([A-Z0-9_]+)/#ifndef \1\n\0\n#endif\n/' AK/Debug.h.in
    sed -i -E 's/#cmakedefine01 ([A-Z0-9_]+)/#ifndef \1\n\0\n#endif\n/' Kernel/Debug.h.in

3a3270eb68 LibELF: Make a dummy VM reservation before mapping dynamic objects
Using the text segment for the VM reservation ran into trouble when
there was a discrepancy between the p_filesz and p_memsz.

Simplify this mechanism and avoid trouble by making the reservation
as a MAP_PRIVATE | MAP_NORESERVE throwaway mapping instead.

Fixes #5225.

a59b1825ce LibWeb: Basic implementation of global event handlers :^)
Document and HTMLElement now inherit from HTML::GlobalEventHandlers
which allows them to support "onfoo" event handler attributes.

These are assignable both via IDL attributes and content attributes.

Event listeners constructed this way get a special "attribute" flag
on them so we know which one to replace if you reassign them.
This also allows them to coexist with EventTarget.addEventListener().

This is all a bit sloppy, but it works decently for a first cut.
The Window object should also inherit GlobalEventHandlers, but since
we don't generate it from IDL, I haven't taken that step here.

Also this would be a lot nicer if we supported IDL mixins.

d24e287f8c Base: Make /www read-write by default
Since it is owned by root anyway, there is no need for 'additional security' to prevent
modification of that directory. This makes it easier to quickly export files from
Serenity. Fixes #5152.

c10e0adaca Kernel: Move perf event backtrace capture out of Thread class
There's no need for this to be generic and support running from an
arbitrary thread context. Perf events are always generated from within
the thread being profiled, so take advantage of that to simplify the
code. Also use Vector capacity to avoid heap allocations.

cc2f35badd TextEditor: Implement word wrapping
Add a new wrapping mode to the TextEditor that will wrap lines at the
spaces between words.

Replace the previous menubar checkbox 'Wrapping Mode' in HackStudio and
the TextEditor with an exclusive submenu which allows switching between
'No wrapping', 'Wrap anywhere' and 'Wrap at words'. 'Wrap anywhere' (the
new 'Wrap lines') is still the default mode.

Setting the wrapping mode in the constructors of the TextEditorWidget
and HackStudio has been removed, it is now set when constructing the
menubar actions.

36f6351edc Kernel: Restore IDE PIO functionality
This change can be actually seen as two logical changes, the first
change is about to ensure we only read the ATA Status register only
once, because if we read it multiple times, we acknowledge interrupts
unintentionally. To solve this issue, we always use the alternate Status
register and only read the original status register in the IRQ handler.

The second change is how we handle interrupts - if we use DMA, we can
just complete the request and return from the IRQ handler. For PIO mode,
it's more complicated. For PIO write operation, after setting the ATA
registers, we send out the data to IO port, and wait for an interrupt.
For PIO read operation, we set the ATA registers, and wait for an
interrupt to fire, then we just read from the data IO port.

a8dfba6348 HackStudio: tree_view on_activiation changes
When opening a file in the tree view with _double click_, the file name
was not the same as opening the same file with _right click > Open_.

This caused the opne_files_view to have the same file in it, but with
two different names.

df7ddfb803 LibELF: Mark libc.so and libpthread.so as syscall regions

823186031d Kernel: Add a way to specify which memory regions can make syscalls
This patch adds sys$msyscall() which is loosely based on an OpenBSD
mechanism for preventing syscalls from non-blessed memory regions.

It works similarly to pledge and unveil, you can call it as many
times as you like, and when you're finished, you call it with a null
pointer and it will stop accepting new regions from then on.

If a syscall later happens and doesn't originate from one of the
previously blessed regions, the kernel will simply crash the process.

d4f40241f1 Ext2FS: Avoid unnecessary parent inode lookup during inode creation
Creation of new inodes is always driven by the parent inode, so we can
just refer directly to it instead of looking up the parent by ID.

9e4dd834ab Ext2FS: Simplify inode creation by always starting empty
We had two ways of creating a new Ext2FS inode. Either they were empty,
or they started with some pre-allocated size.

In practice, the pre-sizing code path was only used for new directories
and it didn't actually improve anything as far as I can tell.

This patch simplifies inode creation by simply always allocating empty
inodes. Block allocation and block list generation now always happens
on the same code path.
