Release v7.4.0

• mkvmerge: bug fix: mkvmerge was sometimes dropping lines from teletext subtitles read from MPEG transport streams. See #773.
• mkvmerge: bug fix: The PCM packetizer was producing wrong track statistics by disregarding the last packet’s duration when reading PCM data from packaged sources (Matroska, MP4 files). Fixes #1075.
• build system: enhancement: configure will look for a system version of the pugixml library and use that instead of the bundled version if it is found. Fixes #1090.
• mkvextract: bug fix for chapter & tag extraction: If locale is set to a non-UTF locale (including C or POSIX) then no XML data was output at all even if the XML data contained ASCII characters only. Fixes #1086. This also fixes mkvextract writing two BOMs when extracting tags with the »–redirect-output« option on Windows.
• mkvinfo: bug fix: summary mode: reported frame types in block groups are now derived from the number of references found and not by the references’ values.
• mkvmerge: bug fix: Fixed muxing open GOPs after I frames in MPEG-1/2 video (patch by Stefan Pãschel). Fixes #1084.
• mmg: bug fix: VP9 video tracks are accepted in WebM mode.
• mkvmerge: bug fix: Cherry-picked several commits from DivX’ mkvmerge fork for improved HEVC handling. Fixes #1076.
• all: new feature: added a Catalan translation of the programs by Antoni Bella Pãrez
• mkvmerge: bug fix: Fixed the handling of Big Endian PCM tracks read from MP4 files. Fixes #1078.
