This is a manual but clean revert of all commits from #12595.
Adding a partial implementation of the resizable ArrayBuffer proposal
without implementing all the updates to TypedArray infrastructure that
is also covered by the spec introduced a bunch of crashes, so we
decided to revert it for now until a full implementation is completed.
Stub out the FileWatcher class with ENOTSUP stubs to let Services that
require it to compile for Lagom. Later we should add real code for this
using techniques like Linux's inotify(7).
This commit has no behavior changes.
In particular, this does not fix any of the wrong uses of the previous
default parameter (which used to be 'false', meaning "only replace the
first occurence in the string"). It simply replaces the default uses by
String::replace(..., ReplaceMode::FirstOnly), leaving them incorrect.
The POSIX documentation for `endgrent` only mentions that it "closes
the group database", not that it clears the backing storage for return
values. This means that applications might make use of the returned
values even after closing the group database itself. This includes our
own implementations for `getgrnam` and `getgrgid`.
The specification also states that "the storage areas might be
overwritten by a subsequent call to `getgrgid`, `getgrnam`, or
`getgrent`". This implies that `getgrgid` and `getgrnam` aren't meant
to have their own static storage and instead rely on the storage of
`getgrent`.
The main thing that is missing is validating certain pieces of data
against XML productions in well-formed mode, but nothing uses
well-formed mode right now.

Previously we would just tightly pack the different libraries' TLS
segments together, but that is incorrect, as they might require some
kind of minimum alignment for their TLS base address.
We now plumb the required TLS segment alignment down to the TLS block
linear allocator and align the base address down to the appropriate
alignment.
glibc before 2.28 defines major() and minor() macros from sys/types.h.
This triggers a Lagom warning for old distros that use versions older
than that, such as Ubuntu 18.04. This fixes a break in the
compiler-explorer Lagom build, which is based off 18.04 docker
containers.
We had a really naive and simplistic implementation, which lead to
various issues where the optimiser incorrectly rewrote the regex to use
atomic groups; this commit fixes that.
This a simple RAII helper for the BorderRadiusCornerClipper it
samples under the corners on construction, then blits them back
on exiting the scope. This encapsulates a fairly common pattern.
Note: With this change the border-radius is clipped if ethier the
overflow-x or overflow-y is hidden (it is a little unclear what
happens if just one is set, but it seems like most browsers
treat one set + border-radius the same as if overflow: hidden
was set).
JsonArray.h does not #include the definition of JsonValue::serialize, as
it lives in JsonObject.h. The macOS Clang target handles symbol
visibility slightly differently (I couldn't figure out how exactly), so
no visible instantiation ended up being created for the function,
causing a link failure.
