Have animations more closely match the HTML spec
These two commits do two major things:
**Have animations ticks trigger a restyle**: This corrects synchronization issues with animations,
where the values used in layout are out of sync with what is returned by `getComputedStyle`.
**Tick the animation timer in script according to spec**: This greatly reduces the flakiness of
animation and transitions tests.
Fixes#13865.

This doesn't change any expectation because we're not setting
response.redirected properly so all the tests fail later on when it's
asserted to be true.
Fixes#25257
This change corrects synchronization issues with animations, by
reworking the animation processing model to do a quick restyle and
incremental layout when ticking animations.
While this change adds overhead to animation ticks, the idea is that
this will be the fallback when synchronous behavior is required to
fulfill specification requirements. In the optimistic case, many
animations could be updated and applied off-the-main-thread and then
resynchronized when style information is queried by script.
Fixes#13865.

Handle access-control header wildcards
<!-- Please describe your changes on the following line: -->
We were checking Access-Control-Expose-Headers for wildcards inconsistently and then discarding the result; this fixes the check and its use, passing the WPT test for having a wildcard there.

Upgrade to rustc 1.43.0-nightly (5d04ce67f 2020-02-13)
~This Nightly doesn’t have rustfmt, so merging this PR is blocked on https://github.com/rust-lang/rust/issues/68917 and upgrading to a Nightly with the fix.~
Fixes#25550
Add OpenSSL 1.1.1 build check, Update HSTS Preload list
* This variant also works with cross-compilation. PR should fail in CI on Android at first:
The net crate successfully compiled after switching to OpenSSL 1.1.1 on Android. It seemed openssl.sh doesn't need any changes.(?)
* Updated HSTS preload list and public suffix list.
* Configured OpenSSL [SECLEVEL=2](https://www.openssl.org/docs/man1.1.1/man3/SSL_CTX_set_security_level.html) like [Debian](https://wiki.debian.org/ContinuousIntegration/TriagingTips/openssl-1.1.1) Stable:
> As a result RSA, DSA and DH keys shorter than [2048 bits](16a5a9bb78/docs/BR.md (6153-subscriber-certificates)) and ECC keys shorter than 224 bits are prohibited.
* Although all other crates compile I generally get a `libscript-fe019dd3e0a4e06d.rlib: bad extended name index at 8` error on simpleservo_jniapi, I guess Debian Testing is too new and I just haven't found the right steps so far.

Fix HSTS
The headers crate does not [expose](0c42ad8cf5/src/common/strict_transport_security.rs (L42)) HSTS struct fields. At the moment, it's only usable for HSTS header encoding. An update of the headers crate would require a huge update of http, hyper, hyper_serde, net::decoder as well. Therefore I've copied the `typed_get::<StrictTransportSecurity>` decoding feature for now, but with exposed struct fields. Let's remove this custom struct with the next hyper upgrade. I tried to prevent needless HSTS database lookups when network.enforce_tls.enabled is set.

Let hyper automatically set the host header if needed
Google's gws web server did not expect to receive an unneeded Host header via HTTP/2, therefore it responded with 400 Bad Request over a working HTTP/2 connection.
https://tools.ietf.org/html/rfc7540#page-55
> Clients that generate HTTP/2 requests directly SHOULD use the ":authority" pseudo-header field instead of the Host header field.
It's hyper's job to take care of this for the HTTP/1 case, therefore we can remove old code.
When calling [Client::builder()](1974c875a1/components/net/connector.rs (L116-L119)) we do not disable hyper's default [set_host](4b6099c7aa/src/client/mod.rs (L1019-L1024)) config option, therefore hyper [automatically adds a Host header for non-HTTP/2 connections](4b6099c7aa/src/client/mod.rs (L289-L292)) based on the [URI](3f663d7ab2/components/net/http_loader.rs (L418-L421)).

Add start_time to resource timing.
<!-- Please describe your changes on the following line: -->
`start_time` property added to `ResourceFetchTiming`, which enables the setting of `start_time` in the `PerformanceEntry` member of `PerformanceResourceTiming`.
Following the specification at https://w3c.github.io/resource-timing/#dfn-starttime, `start_time` is set to the value of `redirect_start` if redirection occurs and the timing allow check passes. Otherwise it has the same value as `fetch_start`.
