Just because we're calling into the component manager for a service
doesn't mean that we're on a thread that has an associated event loop to
spin. If we are lacking such an event loop, we shouldn't try to
NS_ProcessNextEvent, because that will wind up asserting that there's no
event queue. Instead, just yield with the expectation that some other
thread is making progress on constructing the service that we want.
Before this set of patches, the decision of exposing the stream as a pipe was
centralized in IPCStreamUtils, based on the total expectation size of the IPC
message. This triggers issues when multiplex inputStreams contain something
that cannot be sent as a pipe (IPCBlobInputStream, for instance), or something
that it's better to do not set as a pipe (nsFileInputStream), together with
memory streams (nsStringInputStream), which could make the IPC message greater
then what accepted (1mb).
These patches move the "pipe vs non-pipe" choice into the single inputStream
implementation.
In order to test the test harness's handling of a process failing to
produce a leak log, add a special function that disables the bloat log
output.

We lose some sugar but gain some safety. This seems like the right
trade. If people want sugar they should use Rust.

This commit adds categories to all markers. This way the profiler's
marker categories and frame label categories agree. There are a few
duplicate category properties on some of the marker payloads, but
this could be cleaned up in a follow-up if needed.

I'm always forgetting which code path is which. So give both these
functions clearer names that say if they're used by profiling or telemetry.

This is a better place for it and is more appropriate given that it
already exports to mozilla/DataMutex.h. I'll fix the rvalue reference
problems in a follow up.

This patch implements -moz-gtk-csd-hide-titlebar-by-default media query
to check if the system titlebar should be disabled by default on Linux systems
(it's already disabled on Window/Mac).
It also removes explicit definition of browser.tabs.drawInTitlebar preference on Linux.
When browser.tabs.drawInTitlebar is missing the -moz-gtk-csd-hide-titlebar-by-default
is used to obtain the titlebar state. When browser.tabs.drawInTitlebar is set
in about:config or by Customize menu, the user peference is used instead of the default.
It also fixes a -moz-gtk-csd-available media query,
it was always true regardless the actual system setting.

Currently nsAppRunner is responsible for choosing or creating a profile to use
at startup. It then has to create a reset profile if necessary and lock the
selected profile directories. But these latter things are done in different
places of the selection code and done in different ways, sometimes we delay
while trying to get the lock, sometimes we don't.
This patch moves the profile selection part of the code to its own function so
that then we only have to have one place that does the profile reset and
locking logic.
It makes a lot of sense to have the selection code live in the profile service.
It can use information from the database load to help make the choices and it
also means that we can expose the profile selection code through xpcom allowing
it to be easily automatically tested. It will also be more important for future
patches for the dedicated profiles feature.

AsyncWaitRunnable holds a strong reference to its stream, and
NonBlockingAsyncInputStream holds a strong reference to the
runnable. The cycle gets broken in the RunAsyncWaitCallback() method
of the stream, but if the runnable is cancelled then we leak them
both. This patch fixes that by clearing the pointer to the stream when
the runnable is cancelled, breaking the cycle.
