[Debian-med-packaging] Bug#879886: libhts2: libhts2 needs to handle ABI changes

[Diane Trout]

Hi everyone,

I talked some with upstream about the symbols issues with htslib2

https://github.com/samtools/htslib/issues/616

They think that cram/*.h are private headers, but because we have a
policy of avoiding convenience copies we made those functions public[1]
because a few applications embed htslib and directly use the private
headers.

I do think we should bring back the symbols file, but I was wondering
if we should split the cram headers into a libhts-private-dev so we can
at least track what is depending on the non-public api.

I did realize that my thought about updating the SOVERSION might be
wrong because I was just looking in the source tree for the removed
functions but I should have been checking the public header files.

Diane
