We only have this so that ::-moz-placeholder keeps serializing as
::-moz-placeholder, but I don't think anybody really cares.
Edge aliases ::-webkit-input-placeholder to ::-ms-input-placeholder at parse
time as well, as can be seen in:
```
let s = document.createElement('style');
s.innerHTML = `input::-webkit-input-placeholder { color: red };`;
document.body.appendChild(s);
document.body.innerHTML = s.sheet.cssRules[0].cssText;
```
And I think this is more consistent with what we do for CSS properties that are
aliases.

This would fix this bug as well as webcompat/web-bugs#17900.
The argument for this to be a reasonable change is that, table cells can
never shrink below the min intrinsic size, so overflow-wrap: break-word
doesn't make any sense in table when it didn't affect intrinsic size.
So this change basically revert the behavior of bug 1472386 for tables
which seems to be the biggest problem so far.

Looks like these used this mechanism for no great reason, and actually doing
this exposes trivially whether fingerprinting-resistance is enabled, which looks
like an anti-goal (if a media query parses correctly, and doesn't match either 1
or 0, then fingerprinting-resistance is enabled).

Always assume allowed-for-all-content. There are a couple callers which weren't
doing that:
* A unit test -> removed.
* ComputeAnimationDistance: Used for testing (in transitions_per_property), and
for the animation inspector. The animation inspector shouldn't show
non-enabled properties. The transitions_per_property test already relies on
getComputedStyle stuff which only uses eForAllContent.
* GetCSSImageURLs: I added this API for the context menu page and such. It
doesn't rely on non-enabled-everywhere properties, it was only using
eInChrome because it was a ChromeOnly API, but it doesn't really need this.

The loop was mutating the nsCSSPropertyID used to guard the exit, which is
obviously wrong.
This branch is pretty rarely taken, since people don't usually specify `all` as
a transition property other than the first, for which case we take the fast path
with `checkProperties = false`. Our test-suite failed to catch this.
Added a crashtest that hangs without this patch.
The reason bug 1478990 regressed this is because it changed the order of
nsCSSPropertyID so that `p` actually went backwards causing the infinite loop,
but the bug was introduced (by me, whoops) in bug 1309752.

The '-moz-menulist-button' value currently behavies identically to the
'menulist-button' value. This is not implemented as an alias because later
patches in this patch series will change the behavior of our pre-existing
'menulist-button' value to more closely match what Chrome does.

Everything that goes in a PLDHashtable (and its derivatives, like
nsTHashtable) needs to inherit from PLDHashEntryHdr. But through a lack
of enforcement, copy constructors for these derived classes didn't
explicitly invoke the copy constructor for PLDHashEntryHdr (and the
compiler didn't invoke the copy constructor for us). Instead,
PLDHashTable explicitly copied around the bits that the copy constructor
would have.
The current setup has two problems:
1) Derived classes should be using move construction, not copy
construction, since anything that's shuffling hash table keys/entries
around will be using move construction.
2) Derived classes should take responsibility for transferring bits of
superclass state around, and not rely on something else to handle
that.
The second point is not a huge problem for PLDHashTable (PLDHashTable
only has to copy PLDHashEntryHdr's bits in a single place), but future
hash table implementations that might move entries around more
aggressively would have to insert compensation code all over the place.
Additionally, if moving entries is implemented via memcpy (which is
quite common), PLDHashTable copying around bits *again* is inefficient.
Let's fix all these problems in one go, by:
1) Explicitly declaring the set of constructors that PLDHashEntryHdr
implements (and does not implement). In particular, the copy
constructor is deleted, so any derived classes that attempt to make
themselves copyable will be detected at compile time: the compiler
will complain that the superclass type is not copyable.
This change on its own will result in many compiler errors, so...
2) Change any derived classes to implement move constructors instead
of copy constructors. Note that some of these move constructors are,
strictly speaking, unnecessary, since the relevant classes are moved
via memcpy in nsTHashtable and its derivatives.
And general Element logging. We now print all the attributes for comparison.
If this turns out to be too verbose we can change it to diff them or something.

We have a different order in nsCSSPropertyId for no good reason. The only
invariant there is that longhands come before shorthands, and shorthands before
aliases.
Luckily that's also an invariant that NonCustomPropertyId has, so we can reuse
them.

With the current early-returning behavior, the expression will unconditionally
evaluate to false, which is a bit of a footgun.
Make sure to always return no-preference in unsupported platforms or when

DocShells are associated with outer DOM Windows, rather than Documents, so
having the getter on the document is a bit odd to begin with. But it's also
considerably less convenient, since most of the times when we want a docShell
from JS, we're dealing most directly with a window, and have to detour through
the document to get it.
