2f0e3da142 AK: Add IPv6Address class 
This is the IPv6 counter part to the IPv4Address class and implements
parsing strings into a in6_addr and formatting one as a string. It
supports the address compression scheme as well as IPv4 mapped
addresses.

9d8da1697e AK: Automatically shrink HashTable when removing entries 
If the utilization of a HashTable (size vs capacity) goes below 20%,
we'll now shrink the table down to capacity = (size * 2).

This fixes an issue where tables would grow infinitely when inserting
and removing keys repeatedly. Basically, we would accumulate deleted
buckets with nothing reclaiming them, and eventually deciding that we
needed to grow the table (because we grow if used+deleted > limit!)

I found this because HashTable iteration was taking a suspicious amount
of time in Core::EventLoop::get_next_timer_expiration(). Turns out the
timer table kept growing in capacity over time. That made iteration
slower and slower since HashTable iterators visit every bucket.

eb829924da AK: Remove return value from HashTable::remove() and HashMap::remove() 
This was only used by remove_all_matching(), where it's no longer used.

623bdd8b6a AK: Simplify HashTable::remove_all_matching() 
Just walk the table from start to finish, deleting buckets as we go.
This removes the need for remove() to return an iterator, which is
preventing me from implementing hash table auto-shrinking.

feb00b7105 Everywhere: Make JSON serialization fallible 
This allows us to eliminate a major source of infallible allocation in
the Kernel, as well as lay down the groundwork for OOM fallibility in
userland.

7e18e6e37b AK: Skip over initial empty chunks in DisjointChunks 
This will be caught by new test cases: when the initial chunk is empty,
a dereference before calling operator++ on the iterator will crash as
the initial chunk's size is never checked.

4ec599aae5 AK: Make DisjointChunks support FixedArray

ee9eef1fa8 AK: Make DisjointChunk::append move the new chunk 
Previously, although we were taking a moved chunk, we still copied it
into our chunk list. This makes DisjointChunk compatible with containers
that don't have a copy constructor but a move constructor.

b7110c2a34 AK: Add constructor to create Span from Array

d29d9462e9 AK: Suppress clang-tidy warning on TODO() 
This adds a NOLINT directive to the definition of the TODO() macro.
clang-tidy wants the assert replaced with a static_assert, since the
macro simply resolves to assert(false). This is obviously nonsensical,
since we want the code to still compile even with TODO().

The same fix has already been implemented for VERIFY_NOT_REACHED().

1a4dd47d5f AK: VERIFY inside release_value_but_fixme_should_propagate_errors() 
While the code did already VERIFY that the ErrorOr holds a value, this
was done by Variant, so the error message was just that `has<T>()` is
false. This is less helpful than I would like, especially if backtraces
are not working and this is all you have to go on. Adding this extra
VERIFY means the assertion message (`!is_error()`) is easier to
understand.
