some additional functions for parity with recalcUnicodeRanges.

2a1f09dbb2 Don’t calculate whole sets of unicode codepoints 
_getUnicodeRangeSets used to calculate sets containing lots of numbers, only to
get intersections between a set and ranges. Creating and manipulating a lot of
big sets requires a lot of memory.

The function has been replaced by _getUnicodeRanges, returning a list of range
starts boundaries and a list of range stops + corresponding bits.

Tests on intersectUnicodeRanges save about 130 MB (!) of RAM, with no
significant speed penalty.

28bb992c1f replace int(round(...)) with round(...) 
We don't need to cast to int when using the round function from py23,
as this is a backport of python3's built-in round and thus it returns
an int when called with a single argument.
