Since bug 635961, building with relro makes elfhack try to use the bss
data for a temporary function pointer. If there is not enough space for
a pointer in the bss, elfhack will complain it couldn't find the bss.
In normal circumstances, this is most likely fine. Libraries with a bss
so small that it can't fit a pointer are already too small to be
elfhacked anyways. In Firefox, the two libraries with the smallest bss
have enough space for two pointers, and aren't elfhacked (libmozgtk.so
and libplds4.so).
However, the testcase that is used during the build to validate that
elfhack works doesn't have a large enough bss on x86-64, making elfhack
bail out, and the build fail as a consequence.
This, in turn, is due to the only non-thread-local zeroed data being an
int, which is not enough to fit a pointer on x86-64. We thus make it a
size_t.

This avoids large gaps in the profiler output.
Sometimes we hold on to exit profiles for a long time before a profile is
gathered. During that time, the parent process's profile buffer might have
looped around several times. At that point, profiles from processes that have
exited long ago are no longer interesting.

Extract CSSFontFeatureValuesRule from nsCSSFontFeatureValuesRule
class. This is necessary because we will create a FontFeatureValues
rule for Servo side.
