Update devtools/import.py and import/pysam.* for 1.15

Exclude samtools/bam2bcf.[ch] which (starting in samtools 1.15) are only
used by bam_tview.c (which we already exclude) and contain functions that
collide with bcftools. Remove obsolete exclusions for removed items.

In import/pysam.h, add prefixes to several more functions that otherwise
conflict between libcsamtools and libcbcftools. Fixes pysam-developers#1081.

In bcftools/regidx.h, add prefixes to all functions, as these conflict
with those provided by htslib/htslib/regidx.h. This is done locally
within bcftools (rather than via import/pysam.h) as this issue may
be resolved in future bcftools imports by PR samtools/bcftools#865.
