CachePerfStats gathers performance data for single open, read and write operations as well as the whole cache entry opening. It maintains long term and short term average. The long term average filters out excessive values and it represents and average time for a given operation when the cache is not busy. The short term average represents the current cache speed. By comparing these two stats we know pretty quickly that the cache is getting slower and then we race the cache with network immediately without a delay. Otherwise the delay is based on the average cache entry open time.

This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.

Bug 1374173 seems to be the cause of all MediaCache intermittent assertion
failures. It's not an important bug, so let's back-out and verify that
intermittents disappear.

On Linux some implementations of time(0) appear to be suffering from integer
overflow and giving us the wrong dates. This causes the time we expose to the
CDM to be wrong, and so licenses passed to the CDM are failing to authenticate,
and Netflix is thus broken on some Linux systems.
This is only happening in Firefox 54 and earlier, as in those versions we use
the WidevineDecryptor to talk to the CDM. In 55 (in beta) and later we use the
PChromiumCDM protocol to talk to the CDM. This doesn't use time(0) to get a
time for the CDM, so it's immune to the problem here.
So this patch makes the GetCurrentWallTime() implementation in
WidevineDecryptor match the code currently being used on Nightly and Beta in
the ChromiumCDMChild::GetCurrentWallTime() function.
Since we use the PChromiumCDM protocol to talk to the CDM on Nightly and Beta
by default, the WidevineDecryptor isn't actually being used on Nightly and
Beta. So this patch will only cause a behaviour change in Release, which still
uses the old backend. However it will make Release run the same code that we're
running in Nightly and Beta, so it should be safe to uplift to Release.
