This more concrete wrapper type can write a prefix the very first time something
is written to it. This allows removing plenty of useless monomorphisations caused
by the former W/SequenceWriter<W> pair of types.
It's not only more consistent (since we have a proper ParserContext there), but
also fixes a bunch of bugs where Gecko accidentally exposes and allows setting
internal state because of conversions from nsCSSPropertyID to PropertyId.
This adds the extra complexity of caring about aliases for longer, but that's
probably not a big deal in practice, since we also have PropertyDeclarationId.

Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`.
`malloc_size_of` is better -- it handles various cases that `heapsize` does not
-- so this patch changes Servo to use `malloc_size_of`.
This patch makes the following changes to the `malloc_size_of` crate.
- Adds `MallocSizeOf` trait implementations for numerous types, some built-in
(e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`).
- Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't
support that operation.
- For `HashSet`/`HashMap`, falls back to a computed estimate when
`enclosing_size_of_op` isn't available.
- Adds an extern "C" `malloc_size_of` function that does the actual heap
measurement; this is based on the same functions from the `heapsize` crate.
This patch makes the following changes elsewhere.
- Converts all the uses of `heapsize` to instead use `malloc_size_of`.
- Disables the "heapsize"/"heap_size" feature for the external crates that
provide it.
- Removes the `HeapSizeOf` implementation from `hashglobe`.
- Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of`
doesn't derive those types, unlike `heapsize`.
Fixes warnings from rust-lang/rust#44229 when `--enable-commonmark` is
passed to rustdoc.
This is mostly a global find-and-replace for bare URIs on lines by
themselves in doc comments.
The declaration can indeed have the same id if it contains variables, or is a
CSS keyword value.
This was making a WPT test fail, so this is tested, though Servo's WPT import
didn't catch this for some reason.
This introduces DeclarationSource, to see if a declaration has been parsed or
set from CSSOM in a declaration block.
The Servo_DeclarationBlock_SetFoo and similar callers are changed to
DeclarationSource::CssOm because their semantics are more CSSOM-y, but it
shouldn't matter since they should all be checked before hand with
Servo_DeclarationBlock_PropertyIsSet.
… rather than the start location of the current construct.
This likely places the error just *after* of the unexpected token
whereas before would be best, but that’s likely a much bigger change.

I'm about to introduce more state here to implement optimizations for custom
property cascading, so this abstraction is useful to encapsulate that state.
We have three different enums to represent slightly different things. Reuse them
properly, and kill some code in the animated_properties module while at it.

This patch makes the MallocSizeOf stuff in Stylo work more like the HeapSizeOf
stuff already in Servo, except better. In particular, it adds deriving support
for MallocSizeOf, which will make it easier to improve coverage.
The patch does the following.
- Combines servo/components/style/stylesheets/memory.rs and the heapsize crate
into a new crate, malloc_size_of.
- Forks the heapsize_derive crate, calling it malloc_size_of, so that
MallocSizeOf can be derived.
- Both the new crates have MIT/Apache licenses, like heapsize, in case they are
incorporated into heapsize in the future.
- Renames the methods within MallocSizeOf and the related traits so they are
more concise.
- Removes MallocSizeOfWithGuard.
- Adds `derive(MallocSizeOf)` to a lot of types, in some cases replacing an
equivalent or almost-equivalent hand-written implementation.
- Adds stuff so that Rc/Arc can be handled properly.
style: Avoid scanning the longhand id twice in the fast path of PropertyDeclarationBlock::parse_common
This makes the overhead of this function much lower according to `perf`.
And in general makes sense, removing overhead from the fast path.

Devirtualize CSS error reporting.
This removes a trait object from the path of reporting a CSS error.

This is a temporary step needed to support Gecko's getKeyframes() API
until we implement bug 1391537. It only takes effect when
a ComputedValues object is supplied and only for longhand declarations.
