    libxml2: Add abi version
    
    The version of libxml2 was bumped from 2.13.6 to 2.14.5. Since version
    2.14, libxml2 is not binary compatible with older versions. Therefore
    add an abi version.
    
    From the NEWS file:
    Binary compatibility is restricted to versions 2.14 or newer. On ELF
    systems, the soname was bumped from libxml2.so.2 to libxml2.so.16.
