Many object store related operations require the transaction to be
checked: to ensure it is still active, and, if the operation is a write,
that the transaction is not read-only. I've added the
`check_transaction` method to perform these checks.
Additionally `Clear` was still half-implemented, so I went ahead and
implemented that.

This change refactors how we notify DevTools about network activity so
that all fetches (even those served from cache) appear correctly in the
Network panel, and so that DevTools sees request metadata as soon as
possible rather than waiting until the end of a full HTTP cycle.
- Before, we only send DevTools events inside http_network_fetch, so
cached responses (which skip that path) never show up. By emitting a
minimal HttpRequest event at the very start of main_fetch (with URL,
method, pipeline and browsing IDs), we guarantee every fetch shows up
immediately.
- Then, by moving HttpResponse notifications out of http_network_fetch
into main_fetch (right after process_response and process_response_eof),
we ensure DevTools gets status, header, and completion events for both
network and cache hits. Leveraging nullable fields in NetworkEventActor
lets us incrementally fill in timing, header, and body data later,
improving DevTools’ visibility.
Testing: Ran servo with `--devtools=6080` flag, cached responses now
appear in the network panel

Digging into several crashing tests revealed that committing
transactions is a fallible operation. Propagating those errors led to
exposing many new errors caused by the IDBRequest implementation
assuming that all successful responses contained a structured clone. The
end result is a bunch of new test failures that were previously hidden.
Testing: Existing test coverage is sufficient.

The cookie-rs library parses the cookie expiry date based on the format

The will-navigate message tells the devtools client to expect a
navigation for a browsing context. This makes the network monitor clear

This creates a new method in shared/compositing/lib to generate image
keys that are send over the webview. This does not immediately return
the keys but goes over the constellation to receive the keys from the
IOCompositor. To make this more efficient, we now cache the keys in
image_cache in a simple FIFO order. The old blocking method stays intact
for now but got renamed to make the blocking clear.
The blocking calls that are left are in:
- `components/canvas/canvas_data.rs`
- `components/script/dom/htmlmediaelement.rs`

This change adds support for rendering static SVG images using the
`resvg` crate, allowing svg sources in the `img` tag and in CSS
`background` and `content` properties. There are some limitations in
using resvg:
1. There is no support for animations or interactivity as these would
require implementing the full DOM layer of SVG specification.
2. Only system fonts can be used for text rendering. There is some
mechanism to provide a custom font resolver to usvg, but that is not
explored in this change.
3. resvg's handling of certain edge cases involving lack of explicit
`width` and `height` on the root svg element deviates from what the
specification expects from browsers. For example, resvg uses the values
in `viewBox` to derive the missing width or height dimension, but
without scaling that dimension to preserve the aspect ratio. It also
doesn't allow overriding this behavior.

This makes servo use less file descriptors for animated images and
avoids the crash described in
https://github.com/servo/servo/issues/36792.
Doing this also forces the end users to be more explicit about whether
they want to deal with all image frames or just the first one.
Previously, `Image::bytes` silently returned only the data for the first
frame. With this change there's now a `frames` method which returns an
iterator over all frames in the image.
Testing: No tests - this simply reduces the number of fds used. Servo
doesn't currently display animated gifs anyways.

This reduces the memory used by the preload list to just 1.9MB. The
total memory savings in HSTS from
pre-103cbed928
is now 62MB, or 96%. And in terms of total resident memory is a 7.5%
reduction. The DAFSA/DAWG used by Firefox is 1.1MB so there could be
additional gains available but this seems like the best option based on
maintained libraries available (I could not find a good maintained
library for DAFSAs in Rust).
The main trick is this: the FST map API is currently designed to map
byte sequences to u64 values. Because we only need to determine if a
preloaded domain has the `includeSubdomains` flag set, we encode that
into the lowest bit of the ids in the map. This way finding an entry in
the map directly provides us with the `includeSubdomains` flag and we
don't need to keep another mapping in memory or on disk.
Updated the `./mach update-hsts-preload` command to generate the new FST
map file. (Not sure if I need to update any dev-dependencies anywhere
for this change)
This change also replaces the use of "mozilla.org" with "example.com" in
the HSTS unit tests to make sure that entries in the preload list do not
influence the tests (since example.com should not ever end up on the
preload list)
Testing: Updated unit tests

Combines the 2 time values in the HSTS entry with a single timestamp for
expiration. (9MB savings per list)
The previous time representations were based on system boot time which
meant that the `hsts_list.json` round trip across boots resulted in
completely erroneous expiration times.
The preload list is now initialized separately from the public and
private lists and shared by both, cutting memory use in half.
Overall takes memory use from 64MB for HSTS to 24MB.
Expired HSTS entries are now removed from the list when updating an
entry and subdomains can be added to a list if the superdomain does not
already include them.

Rather than sharing the full image cache in a script_thread, the image
cache is now unique per document. This ensures that CSP factors no
longer affect whether the image is retrieved from the cache incorrectly.
To do so, the thread_pool is shared across all caches, but the store is
fresh. Except for the place_holder{image,url}, which are cloned. That's
because the `rippy_data` is only available in the constellation and no
longer accessible at the point that we need to create the document in
the script_thread.
Contrary to the description in #36505, the script_thread still has an
image_cache for this reason: so it has access to the store and
thread_pool to clone it.
With these changes, the two CSP tests no longer flake. Confirmed with
running the following commmand:

This turned out to be a full rabbit hole. The new header
is parsed in the new `parse_csp_list_from_metadata` which
sets `disposition` to `report.
I was testing this with
`script-src-report-only-policy-works-with-external-hash-policy.html`
which was blocking the script incorrectly. Turns out that there
were multiple bugs in the CSP library, as well as a missing
check in `fetch` to report violations.
Additionally, in several locations we were manually reporting csp
violations, instead of the new `global.report_csp_violations`. As
a result of that, they would double report, since the report-only
header would be appended as a policy and now would report twice.
Now, all callsides use `global.report_csp_violations`. As a nice
side-effect, I added the code to set source file information,
since that was already present for the `eval` check, but nowhere
else.

[ohos](9f93ccd942/ports/servoshell/egl/ohos/simpleservo.rs (L43))
), meaning that the baked in resources
are unused in servoshell.
For 3rd-party embedders, we probably also want to the let them know
early that they should initialize the resources, instead of
restricting the panics to production mode.
Rippy is the only resource which was required. Since it is only
253 bytes large, we just bake that resource in as a fallback.
We do want to make using the resources easy from tests, so we add
some logic to keep the baked in resources for tests only and initialize
the resource reader on first access.
