Currently, you can create a pref that only has a user value, and then later
give it a default value with a different type. The entire pref is then recorded
as having this second type. This causes problems later when interpreting the
user value.
This patch makes SetValue() fail if it tries to set a default value whose type
differs from an existing user value. It also expands an existing test to cover
this case and some similar ones.

This requires adding an aPriority argument (defaulting to false) to
Preferences::RegisterCallback(). And RegisterVarCacheCallback() is no longer
necessary.

- Ensure ovr_GetSessionStatus is polled even when a VR presentation
is not active.
- When we fail to initialize an Oculus Session or detect VR hardware,
immediately unload the Oculus Library as we can't poll for ShouldQuit
without a valid Oculus session.
- When we poll ovr_GetSessionStatus, we are now updating the mounted state
in VRDisplayInfo::mIsMounted.
- Added prefs to control enumeration throttling and timeout to release
VR hardware when inactive.
- Some refactoring to make frame loop more understandable and less
brittle.
- When throttling enumeration, we ensure that all other VR apis
also throttle enumeration so that they don't pick up the same device
during throttling.
- Some long functions in VRManager have been broken up and
had their inner-workings documented in more detail.

We can move the setting into ReplaceValue() and ClearValue(), and then those
methods aren't needed any more.
The patch also removes some getter calls within PrefHashEntry by directly using
field names.

There's an "XXX" comment suggesting a possible leak when string user values are
cleared. Turns out a lot of the time there won't be a leak, because the string
pointer isn't overwritten and ClearEntry() frees the string when the pref is
destroyed. However, if the user value is subsequently overwritten with a
different string, there will be a leak. Also, even in the non-leak case, we
currently hold onto the string for longer than necessary.
This patch introduces ClearUserValue() -- which frees the string when
appropriate -- and uses it in all the places where values are cleared.

- rename it as NotifyCallbacks();
- remove the return value, because it is always NS_OK;
- some minor naming and declaration clean-ups.

It's a horrible method, but the horribleness was pre-existing. I hope to make
it nicer in a follow-up bug.

This moves part of pref_savePrefs() into PrefHashEntry.
This requires moving StrEscape() higher up to avoid a forward declaration.
Note that clang-format insists on indenting an unrelated comment, I don't know
why.

And invert its sense, renaming as Equals(), because that is easier to think
about.
The patch also reorders some conditions so that
HasDefaultValue()/HasUserValue() is tested before Equals(). This isn't strictly
necessary, but it reads better.
