Up until now, Servo was using a very old version of time to get a
cross-process monotonic timestamp (using `time::precise_time_ns()`).
This change replaces the usage of old time with a new serializable
monotonic time called `CrossProcessInstant` and uses it where `u64`
timestamps were stored before. The standard library doesn't provide this
functionality because it isn't something you can do reliably on all
platforms. The idea is that we do our best and then fall back
gracefully.
This is a big change, because Servo was using `u64` timestamps all over
the place some as raw values taken from `time::precise_time_ns()` and
some as relative offsets from the "navigation start," which is a concept
similar to DOM's `timeOrigin` (but not exactly the same). It's very
difficult to fix this situation without fixing it everywhere as the
`Instant` concept is supposed to be opaque. The good thing is that this
change clears up all ambiguity when passing times as a `time::Duration`
is unit agnostic and a `CrossProcessInstant` represents an absolute
moment in time.
The `time` version of `Duration` is used because it can both be negative
and is also serializable.
Good things:
- No need too pass around `time` and `time_precise` any longer.
`CrossProcessInstant` is also precise and monotonic.
- The distinction between a time that is unset or at `0` (at some kind
of timer epoch) is now gone.
There still a lot of work to do to clean up timing, but this is the
first step. In general, I've tried to preserve existing behavior, even
when not spec compliant, as much as possible. I plan to submit followup
PRs fixing some of the issues I've noticed.

`jemallocator` and `jemallocator-sys` crates are same as the `tikv-*`
versions and these aliases were maintained for historical reasons, based
on crates.io documentation. For newer projects, it is recommended to use
the `tikv-` versions of the crate. Even though Servo is not a new
project, it makes sense to switch to the newer version for the sake of
clarity.
Also, more importantly, `tikv-jemallocator` has new release (0.6.0)
which includes a fix for #32720. There doesn't seem to be a
corresponding version publised for the `jemallocator` crate.
Fixes#32720

This is a fix for the crash issue in 64-bit ARM [#32175][1].
When targeting Android 11 and above, 64-bit ARM platforms
have the 'Tagged Pointer' feature enabled by default which
causes memory allocated using the system allocator to have
a non-zero 'tag' set in the highest byte of heap addresses.
This is incompatible with SpiderMonkey which assumes that
only the bottom 48 bits are set and asserts this at various
points.
Both Servo and Gecko have a similar architecture where
the pointer to a heap allocated DOM struct is encoded as
a JS::Value and stored in the DOM_OBJECT_SLOT (reserved
slot) of the JSObject which reflects the native DOM struct.
As observed in #32175, even Gecko crashes with `jemalloc`
disabled which suggests that support for using the native
system allocator with tagged pointers enabled by default
is not present at the moment.

This dependency was forked in ##20641 in order to fix the Android build.
Years have gone by and it's quite likely that many things have changed
in the Android toolchain and these dependencies. We can sort out this
issue when getting the Android build working -- or if all else fails,
disable jemalloc for Android. In the meantime, unfork the dependency and
upgrade it.
Fixes#20645.
This is the start of the organization of types that are in their own
crates in order to break dependency cycles between other crates. The
idea here is that putting these packages into their own directory is the
first step toward cleaning them up. They have grown organically and it
is difficult to explain to new folks where to put new shared types. Many
of these crates contain more than traits or don't contain traits at all.
Notably, `script_traits` isn't touched because it is vendored from
Gecko. Eventually this will move to `third_party`.
This will ultimately make it simpler to update crate dependencies and
reduce duplicate when specifying requirements. Generally, this change
does not touch dependencies that are only used by a single crate. We
could consider moving them to workspace dependencies in the future.
The Linux kernel imposes a 15-byte limit on thread names[1]. This means
information that does not fit in this limit, e.g., the pipeline ID of
layout and script threads, is lost in a debugger and profiler (see the
first column of the table below).
This commit shortens the thread names used in Servo to maximize the
amount of information conveyed. It also rectifies some inconsistencies
in the names.
