This patch also changes the 'headerURL' and 'theme_frame' properties to be of type
ExtensionURL, instead of strings. This improves validation robustness.
Alignment and tiling properties for the additional background images can be
specified in the newly introduced 'properties' section of the manifest.

This patch makes the size of inner windows will be automatically rounded for
either window.open() with window features or setting window size through
innerWidth/Height and outerWidth/Height when fingerprinting resistance is
enabled. If the given value is greater the maximum available rounded size, then
it will be set to the maximum value. Otherwise, the size will be set to the
nearest upper 200x100.
This patch also adds one helper function in nsContentUtils for calculating the
rounded window dimensions.

This patch fixes two related issues.
1. The AutoStopwatch uses a stack-allocated `mozilla::Vector` to
communicate with its callback during each compartment switch. This
vector was designed to allow its contents to be stack-allocated but
they turned out to be accidentally heap-allocated.
2. During each tick, the stopwatch fills a vector
`recentGroups_`. This vector always started with minimal capacity and
had to grow repeatedly as groups were added, causing repeated
reallocations. This patch preallocates `recentGroups_` to have the
same capacity as the previous tick. We expect that this should
eventually reach a stable size that closely matches the actual needs
of the process.

Enable safebrowsing v4 completion but ignore the result by checking preference in
nsUrlClassifierLookupCallback::Completion may cause telemetry measure incorrect match
result since v4 completions will always be ignored.
So in this patch we move the preference check after telemetry is measured and then we
ignore the result.

Also, avoid two entirely unused imports.
This avoids loading the various osfile jsms at startup.
The additional shim method for sysinfo is needed in
test_TelemetryEnvironment.js because delaying the intialization of
osfile results in loading osfile_shared_allthreads.jsm after the shim
sysinfo has been added, which initializes
Ci.nsIOSFileConstantsService, which calls into sysinfo in
InitOSFileConstants().

There are two sets of three probes here.
The first set of probes reports the maximum contiguous frames dropped during
compositor animations. This gives us some idea of the volatility of the
compositor framerate.
The second set of probes reports the frame throughput, which is the number of
actual frames composited divided by the expected number of frames (based on the
vsync interval and wall-clock time) during compositor animations. The ratio is
scaled up to 1000, so values of 1000 should indicate a "perfect score". The
probes use linear bucketing with a max value of 1500 in case we get abnormal
cases where we composite more frames than expected.
Within each set, there is one probe for compositor animations triggered by the
chrome process, one for compositor animations triggered by a content process,
and one for compositor animations driven by APZ.

Currently we hand over a crash ping to the pingsender via a pipe; if the
pingsender fails to send the ping we rely on the CrashManager assembling and
sending one instead. Since the crashmanager is not aware of whether the ping
was sent or not this causes duplication on the server side. To solve this
problem we save the ping to disk instead, read it from the pingsender and
delete the file only if the ping was sent. In this scenario the CrashManager
will know that a ping was already sent and will not send a new one.
This patch removes all the code used to deal with pipes between the telemetry,
crashreporter and pingsender code and also tries to cut down the amount of
platform-specific code we have in this machinery.

The next patch moves nsCSSFontFaceRule into a separate header, which
somehow affects lots of header dependencies. I'm not completely sure
why this happens, though.
