Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

When "mozAwesomebar" is set to inputmode value, that means that the Smart
Location Bar gets focus. In that case, we should notify IME of input scopes
as "URL" because on-screen keyboard for URL has some useful additional keys
but they are not hindrances even when users want to type non-URL text.
On the other hand, MS-IME for Japanese and Google Japanese Input changes their
open state to "closed" if we notify them of URL input scope. A lot of users
complain about this behavior. Therefore, we should notify only them of
"Default" input scope even when "mozAwesomebar" has focus.

This warning is saying the operation may be undefined because the value of

Fortunately, this seems like a typo and we actually meant to assign ->bottom

IMEStateManager has a static instance of InputContext which has some nsString
instances. Then, their members will be released after XPCOM shutdown and
that is detected as unexpected destruction.
Therefore, IMEStateManager should release them by itself at XPCOM shutdown.
Using nsTSubstring::SetCapacity(0) is the simplest way to release only the
string buffers.

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

- Count open file descriptors instead of testing the existence of a file
(because the clipboard is now only reachable through file descriptors,
and not through a file path).
- Use a fixed string instead of a random string. The previous way of
generating a string was non-deterministic, and there was a very small
chance that the generated string was not large enough to trigger the
cache-to-disk-mode.

Ensure that only DataStruct::mData + mDataLen, XOR
DataStruct::mCacheFD is used.
(Previously it was possible that all of these members were populated,
which is a waste of memory.)
The effect of this change is visible when SetTransferData is called
multiple times with the same flavor, but with one below the threshold
for storing in-memory, and the other above (=store in a file).

The cache file is never directly exposed to consumers of DataStruct,
so it does not make sense to keep the clipboardcache file around
forever.
The only change in this commit is to switch from using a filename to
using a file descriptor. In the destructor, the FD is explicitly closed
(which releases the file data). nsAnonymousTemporaryFile takes care
of removing the file when the destructor is not called (e.g. crashes).
Previously, the clipboard cache was stored in a file called:
TmpD/clipboardcache-N
As of this commit, the clipboard cache is stored at:
TmpD/mozilla-temp-randomN (macOS and Linux)
TmpD/mozilla-temp-files/mozilla-temp-randomN (Windows)
(see xpcom/io/nsAnonymousTemporaryFile.{h,cpp} for more details)
To verify that these files are really gone:
1. Create a document with 500k+ characters, open it in Firefox.
2. Copy its content - this will trigger the clipboard cache.
3. Look for the open file descriptor of the deleted file:
( macOS and Linux: )
lsof +L1 | grep mozilla-temp
4. Copy anything (under the 500k threshold), or quit/kill Firefox.
5. Repeat step 3 and observe that the number of file descriptors
has decreased.
