I don't understand how the test ever worked. I think the idea was that each
operation would result in changes to the prefs, because those prefs are the
source of truth for the recent-files list. However, I don't understand why some
tests would not trigger multiple observer callbacks, which should have been a
huge mess.
The new code doesn't observe the prefs at all. Where possible, it waits for an
appropriate promise; in other places it uses `setTimeout()` to wait for the
next tick, relying on the Scratchpad implementation to be done reacting by
then.
Since the original code was event-driven, most tests were split across two
functions. Each test function had the bottom half of one test and the top half
of the next test. The new code uses async/await and can therefore at least
group related functionality into single cohesive test functions. But those test
functions aren't as independent as they look -- most of them still depend on
previous tests to set up the expected starting state.

Tests can use the promise to avoid racing on the text being available and the

"browser.firstrun.*" seems to have been unused since the end of XUL-based
Fennec, whereas the code referencing the "browser.snippets.*" prefs was removed
in bug 1482836.

Now that fields are packed nicely, we can take advantage of the
contiguous layout of POD fields and read/write all the POD fields of a
given size in a single read/write call. For many structs, this should
have little or no effect, but for large structs such as LoadInfoArgs,
this reduces the number of function calls by ~50%.

We're about to start depending on how the fields are packed in a future
patch, so we should add some compile-time checking that our assertions
are correct.

We're going to read and write sentinels slightly differently for
bulk-writing adjacent fields, so let's factor out some reusable code for
doing so.

This patch changes the layout of IPDL-defined structs to order the POD
members by decreasing size, which ensures everything is packed well.
This optimization is only applied to the internal representation; the
external interface (e.g. constructors) is entirely unchaged.

This patch computes an ordering for the fields of an IPDL structure decl
such that they are packed well in memory. We'll take advantage of this
ordering in future patches.

We can totally get there with a negative percentage basis, see comment 0 for an
example.
We could keep the warning like:
NS_WARNING_ASSERTION(clamping_mode == StyleAllowedNumericType::All ||
basis >= 0, "nscoord overflow?");
Which will catch cases where the style system would refuse to parse a negative
<length-percentage>, but we got a negative percent basis, which would be weird.
But that's a bit misleading since right now at least we rely on the caller to do
the appropriate clamping. I also think that NS_WARNING_ASSERTION is not very
useful, since we're not very likely to catch stuff with it. But anyhow, your
call.

This is being changed in Firefox's build config rather than NSPR's
to avoid possibly introducing regressions into other NSPR users due
to bugs in MacOS's poll, such as the POLLPRI issue addressed in the
previous patch. (There is also a known bug when calling poll() with
zero descriptors, but PR_Poll already has code to call PR_Sleep instead
in that case.)

Necko uses a pipe-to-self pattern in its event loop, except that on
Windows the pipe is a socket, and we're checking for PR_POLL_EXCEPT for
Windows-specific reasons and treating it as an error. On Unix this
isn't necessary, and it causes interoperability problems with MacOS,
which asserts POLLPRI (which is what PR_POLL_EXCEPT maps to) as well
as POLLIN on pipes whenever normal data can be read. (This may be a
standards violation by MacOS, but it's simple enough to work around.)
