V42: bigWig and bigBed support with libBigWig

In version 42 we are using libBigWig instead of Kent source to process bigWig and bigBed tracks.

Please note: the resulting binary program querybw was based on libBigWig and has much friendly license, but it doesn't support cache, bwquery was based on Kent source and will be faster when visualize same tracks next time. But both will work fine with the browser.
