355fbcb702 LibJS: Actually implement get_iana_time_zone_offset_nanoseconds()
Instead of hard-coding an UTC offset of zero seconds, which worked for
the sole UTC time zone, we can now get the proper offset from the TZDB!

d527eb62da LibJS: Support non-UTC time zones in Temporal :^)
We can now recognize & normalize all time zones from the IANA time zone
database and not just 'UTC', which makes the LibJS Temporal
implementation a lot more useful! Thanks to the newly added LibTimeZone,
this was incredibly easy to implement :^)

This already includes these recent editorial changes in the Temporal
spec: 27bffe1

205d63c3f0 LibTimeZone: Operate in UTC-only mode when !ENABLE_TIME_ZONE_DATA
Instead of only having dummy functions that don't work with any input,
let's at least support one time zone: 'UTC'. This matches the basic
Temporal implementation for engines without ECMA-262, for example.

f1276144ba LibJS: Check if input was exhausted after parsing UTC offset fraction
Previously parse_time_zone_numeric_utc_offset_syntax() would return true
to indicate success when parsing a string with an invalid number of
digits in the fractional seconds part (e.g. 23:59:59.9999999999).
We need to check if the lexer has any characters remaining, and return
false if that's the case.

d92558b3b3 Applets/Audio: Propagate errors by extracting out GUI initialization
This commit extracts out the GUI initialization in AudioWidget into
the new try_initialize_graphical_elements function. This function
is now able to use try_set_main_widget instead of set_main_widget.
It's only called by the fallible try_create method.

a4b4b358ff AK+Kernel: Remove one_ref_left() footgun
This mechanism was unsafe to use in any multithreaded context, since
the hook function was invoked on a raw pointer *after* decrementing
the local ref count.

Since we don't use it for anything anymore, let's just get rid of it.

08e927f084 Kernel: Synchronize removals from TmpFS inode map
Previously we were uncaching inodes from TmpFSInode::one_ref_left().
This was not safe, since one_ref_left() was effectively being called
on a raw pointer after decrementing the local ref count and observing
it become 1. There was a race here where someone else could trigger
the destructor by unreffing to 0 before one_ref_left() got called,
causing us to call one_ref_left() on a deleted inode.

We fix this by using the new remove_from_secondary_lists() mechanism
in ListedRefCounted and synchronizing all access to the TmpFS inode
map with the main Inode::all_instances() lock.

There's probably a nicer way to solve this.

3550f12543 Kernel: Make ListedRefCounted::unref() call optional list removal helper
Look for remove_from_secondary_lists() and call it on the ref-counting
target if present *while the lock is held*.

This allows listed-ref-counted objects to be present in multiple lists
and still have synchronized removal on final unref.

09c0324880 LibTimeZone: Begin generating GMT offset rules for each time zone
This is a rather naive implementation, but serves as a first pass at
determining the GMT offset for a time zone at a particular point in
time. This implementation ignores DST (because we are not parsing any
RULE entries yet), and ignores any offset patterns of the form "Mon>4"
or "lastSun".

know off-hand what "P" was representing.

d627367489 LibTimeZone: Do not separate the generated data from the main library
This CMakeLists.txt was basically copy-pasted from LibUnicode, where the
generated data is separated into its own library. This was to let other
libraries / applications decide if they actually want to link the data
because it is so large. LibTimeZone's generated data is significantly
smaller, so this separation really isn't needed.

b543c3e490 Meta: Don't assume how each generator wants to generate keyed map names
The generate_mapping helper generates a series of structs like:

    Array<SomeType, 1> s_mapping_key_0 {};
    Array<SomeType, 2> s_mapping_key_1 {};
    Array<SomeType, 3> s_mapping_key_2 {};
    Array<Span<SomeType const>> s_mapping { {
        s_mapping_key_0.span(),
        s_mapping_key_1.span(),
        s_mapping_key_2.span(),
    } };

Where the names of the struct were generated by the format_mapping_name
lambda inside the helper. Rather than this lambda making assumptions on
how each generator wants to name its structs, add a parameter for the
caller to provide a naming formatter.

This is because the TimeZoneData generator will want pretty specific
identifier formatting rules.

3dccaa39d8 AK: Define a traits helper for case-insensitive StringView hashing
Currently, we define a CaseInsensitiveStringTraits structure for String.
Using this structure for StringView involves allocating a String from
that view, and a second string to convert that intermediate string to
lowercase.

This defines CaseInsensitiveStringViewTraits (and the underlying helper
case_insensitive_string_hash) to avoid allocations.

The URLs of the form `help://man/<section>/<page>` link to another help
page inside the help application. All previous relative page links are

much nicer :^)

Note that man doesn't handle these new links, but the previous relative
links didn't work either.

becf74097e Help: Directly launch an app from its help page
Through links in the help page, the user can directly launch the app
whose help page is currently viewed. The idea for this feature came up
in the discussion of #11557
(https://github.com/SerenityOS/serenity/pull/11557#issuecomment-1004830728
). The intention is that the user can simply open the app they are
currently trying to understand, and play around with it, learn by doing,
or follow along with any guide that may be present in the help page. It
feels very great :^)

984bae9038 Help: Refactor link handling
Link handling is now split up between open_page and open_url. While
open_page can handle any sort of input and is responsible for handling
history UI, open_url deals in URLs and takes one of a few different
actions depending on the exact URL given. Currently, only file:// URLs
are handled but this will change in the next few commits.

Note that this commit breaks relative URLs on purpose. After the new
help:// URLs, they won't be needed anyways. The reasoning is that many
URLs not specifically pointing to man page directories will cause a
(non-deadly) unveil violation in `real_path_for`. This specifically
concerns the new application launch URLs that are added in the next
commit.

2f50d8f4d3 AK+LibC+LibPthread: Introduce NoAllocationGuard
NoAllocationGuard is an RAII stack guard that prevents allocations
while it exists. This is done through a thread-local global flag which
causes malloc to crash on a VERIFY if it is false. The guard allows for
recursion.

The intended use case for this class is in real-time audio code. In such
code, allocations are really bad, and this is an easy way of dynamically
enforcing the no-allocations rule while giving the user good feedback if
it is violated. Before real-time audio code is executed, e.g. in LibDSP,
a NoAllocationGuard is instantiated. This is not done with this commit,
as currently some code in LibDSP may still incorrectly allocate in real-
time situations.

Other use cases for the Kernel have also been added, so this commit
builds on the previous to add the support both in Userland and in the
Kernel.

e2c9578390 Kernel: Allow preventing kmalloc and kfree
For "destructive" disallowance of allocations throughout the system,
Thread gains a member that controls whether allocations are currently
allowed or not. kmalloc checks this member on both allocations and
deallocations (with the exception of early boot) and panics the kernel
if allocations are disabled. This will allow for critical sections that
can't be allowed to allocate to fail-fast, making for easier debugging.

PS: My first proper Kernel commit :^)
