Bug 1723237: Remove `vendor` argument from `install_pip_package()` Now that `piptools` is no longer installed from the vendored location, there are no remaining cases where we are doing `install_pip_package()` with a vendored package.

Bug 1723237: Use pip-compile directly from vendored location We've been installing `piptools` so that we can use the `pip-compile` binary. However, we can just as easily do `python -m piptools compile ...` instead, which also allows us to skip a redundant install.

Bug 1726024 - Handle failure to get async shutdown service in GetShutdownBarrier. r?jib Summary: We will fail to get the service if this function is called and we're already in shutdown. Call sites for this function do not guard against doing so (and I'm not sure there's a nice way to check). So we need to handle failure in the function and have call sites check if this failed.

Bug 1532955 - WIP Track available memory on linux. This introduces a low memory watcher that dispatches an offthread read of /proc/meminfo every 1000ms, then determines which information to act on. It works like this: - Get a percentage of... Summary: ...`MemAvailable` versus `MemTotal`. - If memory drops below 5% availability, we are in a memory pressure scenario - If `MemAvailable` is not large enough to accommodate a content process, we are in a memory pressure scenario - If we are in a memory pressure scenario, notify the observers from the main thread. The value I decided to use to represent a content process was based on observation and should be adjusted if it is not representative of what we consider a "typical" content process. This WIP needs the following: - Break out memory pressure monitoring onto its own thread, to avoid getting queued up behind offthread frees. - Finish wiring up `nsIObserver` and use it to shut down the timer, the thread, and meminfo calls. In its current state it will continue polling indefinitely until timers shut down. - Make the polling interval adjustable based on the available memory; we do not need to poll as frequently in extremely high memory scenarios. - Observe user-interaction-active and user-interaction-inactive, and use these to start/stop memory polling. We don't need to poll when the user is inactive. - Create a new notification specific to observed memory pressure. This will let us be more proactive in unloading tabs. - Set a crash annotation when system memory is low. In its current state you can easily test it by making a large allocation (or adjusting any of the memory thresholds). It will fire off a memory-pressure notification in these scenarios.
