style: Fix detection of animations to avoid style flushing in getComputedStyle.
This fixes multiple things:
* EffectCompositor was using the light tree instead of the flat tree.
* When we insert an element inside the document, we may not style it right away
(we mark it for lazy frame construction with the NODE_NEEDS_FRAME). Since we
trigger animations and transitions from the traversal, we can't skip flushing
if we call getComputedStyle on any of those.

Use env::var_os to read paths from the environment
This avoids unnecessary UTF-8 validation on OsStrings that we just pass
back to the OS.

Update bitflags to 1.0 in every servo crate
It still needs dependencies update to remove all the other bitflags
versions.

Add an FFI to create a temporary ServoStyleContext with the animation value.
We need this because we calculate the Cumulative change hints to check
if we can ignore this animation segment.
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`.
CEF: use `cargo rustc -C link-args=…` instead of `#[link_args="…"]`
The latter is an unstable feature that might be changed or removed.

I recently moved that default from libservo to ports/servo,
which made CEF not have it anymore.
The different defaults made `./mach build-cef` after `./mach build`
rebuild many libraries (including serde and all of its recursive dependents)
and take a long time.
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.
