6fa600fce3 LibJS: Fix the execution context for the bytecode interpreter
Because we now push an execution context when creating the "normal"
interpreter without valid environments we have to check for that case
as well when running the bytecode interpreter.

We weren't properly iterating the extension blocks and thought we
encountered an unexpected extension map block, when we really should
have just skipped over it.

ae99cbe534 LibWeb: Treat SVG fill/stroke/stroke-width attributes as CSS properties
Rather than having separate systems for the attributes and their CSS
equivalents, we can treat the attributes as presentational hints and
convert them to CSS properties. This means they can be inherited, as
they should. :^)

As noted, the `fill` and `stroke` attributes do not fully match the
`fill` and `stroke` properties. The CSS spec is still an early draft and
not entirely helpful, so we can just pretend they are the same for now.

This is a bit of a hack to get box content to stop bleeding 1px outside
the border sometimes. We will need to come up with a more general
solution for this problem eventually.

9201f626c1 LibWeb: Use BFC root relative coordinates when flowing around floats
While IFC flows text into a block container, floating objects are
anchored at the BFC root, not necessarily the local block container.

Because of this, we have to use root-relative coordinates when checking
how much space is available in between left and right floated objects.

54beb7433e LibWeb: Place block-level boxes vertically before formatting them inside
Block placement is now divided into a vertical and horizontal step. The
vertical step runs before formatting boxes internally. The horizontal
step still runs after (since we may need the final width value.)

This solves a long-standing architectural problem where IFC didn't know
its origin Y position within the BFC root box. This is required for
figuring out how to flow around floating objects. (Floating objects are
always relative to the BFC root.)

66216d3af6 LibSQL: Add simple REGEXP match
The implementation of LIKE uses regexes under the hood, and this
implementation of REGEXP takes the same approach. It employs
PosixExtended from LibRegex with case insensitive and Unicode flags
set. The implementation of LIKE is based on SQLlite specs, but SQLlite
does not offer directions for a built-in regex functionality, so this
one uses LibRegex.

df6b9cdb0c LibCore+LibC: Enforce the global event loop ban in code
It's a bad idea to have a global event loop in a client application as
that will cause an initialization-order fiasco in ASAN. Therefore, LibC
now has a flag "s_global_initializers_ran" which is false until _entry
in crt0 runs, which in turn only gets called after all the global
initializers were actually executed. The EventLoop constructor checks
the flag and crashes the program if it is being called as a global
constructor. A note next to the VERIFY_NOT_REACHED() informs the
developer of these things and how we usually instantiate event loops.

The upshot of this is that global event loops will cause a crash before
any undefined behavior is hit.

888faa3c9f LibCore: Fix signal handling race condition in EventLoop
The event loop is responsible for handling POSIX signals while it's
running. The signal handler adds the signals to a wake pipe which is
then read after the select'ing code in wait_for_event. Problems happen,
however, when another signal comes in after the select wake: the signal
will interrupt the next syscall, the `read` from the wake pipe, and the
resulting EINTR in wait_for_event causes the program to crash. This is
undesirable. Instead, we want to retry reading as long as we're
interrupted.

a501b9c7df LibCore: Create wake pipe on each thread
After the previous change, the wake pipe was only being created on the
main thread by the main event loop. This change utilizes a flag to
always initialize the wake pipe on other threads. Because the pipe is
quite expensive (it will count towards the file descriptor limit, for
instance), we do the initialization "lazily": Only when an event loop is
constructed and it notices that there hasn't been a wake pipe created on
its thread, it will create the pipe. Conversely, this means that there
are no pipes on threads that never use an event loop.

69c1910037 LibCore: Allow EventLoops to run on multiple threads safely
The event loop system was previously very singletony to the point that
there's only a single event loop stack per process and only one event
loop (the topmost) can run at a time. This commit simply makes the event
loop stack and related structures thread-local so that each thread has
an isolated event loop system.

Some things are kept at a global level and synchronized with the new
MutexProtected: The main event loop needs to still be obtainable from
anywhere, as it closes down the application when it exits. The ID
allocator is global as IDs should not be shared even between threads.
And for the inspector server connection, the same as for the main loop
holds.

Note that currently, the wake pipe is only created by the main thread,
so notifications don't work on other threads.

This removes the temporary mutex fix for notifiers, introduced in
0631d3fed5 .

3d6e08156d LibThreading: Introduce MutexProtected generic synchronization primitive
MutexProtected mirrors the identically-named Kernel primitive and can be
used to synchronize access to any object that might not be thread safe
on its own. Synchronization is done with a simple mutex, so access to a
MutexProtected object is potentially blocking.

Mutex now has an internal nesting variable which is there to harden it
against lock-unlock ordering issues (e.g. double unlocking).

7f1404b870 LibTimeZone: Use /etc/timezone as the basis for the system time zone
This changes LibTimeZone to read the current time zone from the file
/etc/timezone rather than using tzset/tzname. Instead, in a subsequent
commit, LibC's time methods will be changed to used LibTimeZone to
retrieve the system time zone.

Also add an API to set the system time zone. This method is only allowed
when running within Serenity.

6988403d59 DynamicLoader+LibC+LibTimeZone: Include LibTimeZone sources in LibC
LibTimeZone will be needed directly within LibC for functions such as

LibTimeZone isn't its own .so library anymore.

LibTimeZone itself is compiled as an object library to make it easier to
give it generator-specific compilation flags.
