There's no use case for stateful comparators, so they can be just plain
function pointers.
This is used in some hot places like CSS selector matching.

To be able to remove SystemGroup, NS_ReleaseOnMainThreadSystemGroup
needs to have its dependency on SystemGroup removed. Since all
releases using SystemGroup would've released on the main thread anyway
we can safely replace NS_ReleaseOnMainThreadSystemGroup with
NS_ReleaseOnMainThread.
Depends on D64390

To correctly implement this, it must be known on instantiation whether E is
copy-constructible, which is not the case if only a forward declaration is
available. This can be resolved either by making sure a full definition of E is
available, which is preferable. But in cases where this is not (easily) possible,
the information can be explicitly provided by the MOZ_DECLARE_COPY_CONSTRUCTIBLE
and MOZ_DECLARE_NON_COPY_CONSTRUCTIBLE macros. In particular, declarations for
IPDL-declared types are added to nsTArray.h itself, like it was already done
for MOZ_DECLARE_RELOCATE_USING_MOVE_CONSTRUCTOR.

`clone_from_bag` lets Rust code create a thread-safe `HashPropertyBag`
from any kind of `nsIPropertyBag` by cloning its contents. This is
important when you want to use a property bag that's passed to an XPIDL
method off the main thread. An `nsIPropertyBag` passed from JS isn't
thread-safe, since it's cycle-collected, and its properties are
`XPCVariant`s. But a Rust `HashPropertyBag` is, because it's backed by
a non-cycle collected `nsHashPropertyBag`, and the only supported
properties are thread-safe storage variants.
It also marks `HashPropertyBag` as `Send + Sync`, given that the only
way to construct one is through `HashPropertyBag::new`, and
`VariantType` is only implemented for storage variants.
Finally, it adds more type tags for string (narrow and wide) variants,
and changes the `VariantType for nsCString` getter to use
`GetAsAUTF8String`, since that's what mozStorage implements for its
text variant, not `GetAsACString`.

Previously, `mozIStorageConnection#transactionInProgress` returned true
only if a transaction was started via `beginTransaction()`. This meant
that manually executing `BEGIN`, as `Sqlite.jsm` and the Rust bindings
do, wouldn't accurately report if a transaction was in progress.
Similarly, the flag wasn't accurate in cases where SQLite automatically
rolled back a transaction.
Fortunately, SQLite provides the `sqlite3_get_autocommit()` function,
which we can use to determine if a transaction is open or not. This
commit refactors the `transactionInProgress` getter, along with all
`Connection` methods that depend on it, to use the SQLite API instead
of managing that state on the connection. `mozStorageTransaction` and
`Sqlite.jsm` still use their own flags to decide whether to commit
their transactions, for reasons explained in the IDL comment.
This commit also moves `transactionInProgress` to
`mozIStorageAsyncConnection`, so that `Sqlite.jsm` can use it, and
exposes it to Rust.

I originally had this as a few patches, but the work to fix test
failures and get the whole thing into a complete working state
quickly tangled them up. Apologies for that. To summarize what's
going on here, however:
- We introduce two prefs: shutdown.fastShutdownStage and
shutdown.lateWriteChecksStage. The latter pref is set to 1, which
will leave the existing late write checking behavior unchanged.
However, we introduce this pref to make it simpler in the future
to bump the late write checks window earlier in the shutdown cycle.
- We introduce an AppShutdown class, which will house static methods
and a small amount of state for unifying some shutdown logic. Most
importantly, it will now manage the state for app initiated restarts,
as well as the logic for performing a safe fast shutdown.
- We refactored the existing restart code to call into the new
AppShutdown file, so that if we are configured to actually perform
a fast shutdown, we will be able to run the necessary restart logic
immediately before doing so. Previously, the restart logic occurred
later in the shutdown cycle than our late write checking, meaning
if we were to simply exit the process at that point in time, we
would never run the restart coe.
- Lastly, we updated two locations which called TerminateProcess and/or
_exit(0) to call into the AppShutdown method (DoFastShutdown).

This changeset is a simple find and replace of `MOZ_FALLTHROUGH` and `[[fallthrough]]`.
Unfortunately, the MOZ_FALLTHROUGH_ASSERT macro (to assert on case fallthrough in debug builds) is still necessary after switching from [[clang::fallthrough]] to [[fallthrough]] because:
* MOZ_ASSERT(false) followed by [[fallthrough]] triggers a -Wunreachable-code warning in DEBUG builds
* but MOZ_ASSERT(false) without [[fallthrough]] triggers a -Wimplicit-fallthrough warning in NDEBUG builds.

The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more
specific one or replace a header with a forward declaration.

We want to remove flat strings (JSFlatString). With this patch we only expose
linear strings (JSLinearString) to API consumers.
This is very mechanical for the most part, because code typically only cares
about linear strings and not the null-termination aspect.
CTypes's Library.cpp has some Windows-specific code where we relied on null-terminated
strings. This patch adds JS_CopyStringCharsZ for that use case.

A low-frequency error that showed up in telemetry for new bookmark
sync is "Storage operation failed with NS_ERROR_CANNOT_CONVERT_DATA",
which occurs when we try to convert a variant to the wrong type. It
would be helpful to include the type and column names for this case;
for example, "Can't get i32 for column lastModified". Neither the type
nor column name are PII; we want them to show up in telemetry.

This patch adds a fixed-size array of client usages to OriginInfo and modifies
quota tracking APIs to require the client type to be passed in.
A new method ResetUsageForClient is implemented. The method is used during
client-specific origin clearing. ResetUsageForClient is much faster than calling
GetUsageForOrigin and calling DecreaseUsageForOrigin after that.
LockedUsage now has an assertion that verifies that the total sum of client
usages matches total origin usage. This method should be called instead of
touching mUsage directly.
A new assertion is added to GetQuotaObject which verifies that passed file
belongs to the given persistence type, origin, and client.
