Behdad Esfahbod	5d02572034	[set] Add add_sorted_array() Not optimized to use sortedness yet. Also start putting in place infra to faster reject bad data. A version of Chandas.ttf found on some Chrome bots has 660kb of GPOS, mostly junk. That is causing 48 million of set->add() calls in collect_glyphs(), which is insane. In the upcoming commits, I'll be speeding that up by optimizing add_sorted_array(), while also reducing work by rejecting out-of-sort arrays quickly and propagate the rejection.

[set] Add add_sorted_array()

Not optimized to use sortedness yet.  Also start putting in place infra
to faster reject bad data.

A version of Chandas.ttf found on some Chrome bots has 660kb of GPOS,
mostly junk.  That is causing 48 million of set->add() calls in
collect_glyphs(), which is insane.

In the upcoming commits, I'll be speeding that up by optimizing
add_sorted_array(), while also reducing work by rejecting out-of-sort
arrays quickly and propagate the rejection.

[set] Add add_array()

To be used to optimize adding a whole bunch of (sorted) items at the same time,
as in CoverageFormat1.
