lcov: Upgrade to 2.6

Changes from v2.5 release:

- new html2lcov tool
  * Capture source diff and 'baseline' coverage from lcov HTML report - suitable
    as input to generate differential coverage report versus 'now'. See the html2lcov documentation for details.

- new jacoco2lcov tool
  * Translate JaCoCo java coverage data to lcov format - e.g., for multi-language
    coverage reporting or to take advantage of lcov features. See the jacoco2lcov documentation for details.

- new XS back end (on plaforms which support it).
  * C++ implementation of some key types and operations - to improve execution
    time and memory footprint compared to pure Perl.

- various bug fixes and test coverage improvements.
