Merging r6274 through r6281 from branch releases/1.8 to trunk.

- Updates bzip2 to 1.0.8 (which sadly didn't reduce the amount of compile warnings, but let's hope it still improves something)

+
+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)
+
+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
