bzip2: Update to 1.0.8. This changes the upstream to sourceware.org.

1.0.8 (13 Jul 19)
~~~~~~~~~~~~~~~~~

* Accept as many selectors as the file format allows.
  This relaxes the fix for CVE-2019-12900 from 1.0.7
  so that bzip2 allows decompression of bz2 files that
  use (too) many selectors again.

* Fix handling of large (> 4GB) files on Windows.

* Cleanup of bzdiff and bzgrep scripts so they don't use
  any bash extensions and handle multiple archives correctly.

* There is now a bz2-files testsuite at
  https://sourceware.org/git/bzip2-tests.git

1.0.7 (27 Jun 19)
~~~~~~~~~~~~~~~~~

* Fix undefined behavior in the macros SET_BH, CLEAR_BH, & ISSET_BH

* bzip2: Fix return value when combining --test,-t and -q.

* bzip2recover: Fix buffer overflow for large argv[0]

* bzip2recover: Fix use after free issue with outFile (CVE-2016-3189)

* Make sure nSelectors is not out of range (CVE-2019-12900)
