  * Omit resources/extension/demo files from any packaging verification
    because they're unwanted.
  * Update README.source to include some of these changes.
  * Drop "lzma" from build dependencies.
  * Make most patches follow a common format (no timestamps), to avoid
    future churn.
  * debian/patches/chromium_useragent.patch.in renamed to drop ".in",
    OS "Ubuntu" hardcoded with no compilation-release name, and patch
    refreshed to follow new location of source.
  * In debian/rules, use "-delete" flag on find instead of "-exec rm {} \;",
    to be safer and faster.
  * Also don't include python bytecode or cache files in orig tarball,
    and clean then up on "clean" rule.
  * Write the "REMOVED" list files to the root of the orig tarball,
    instead of inside the src/ directory, where they could collide.
  * Fix dpkg-source warning: Clean up python cached bytecode files.
  * Fix dpkg-source warning: Remove autoconf cache.
  * Fix lintian warning: fta and micahg to XSBC-Original-Maintainer.
  * Fix lintian error not-binnmuable-all-depends-any.
  * Override lintian complaints ancient-autotools-helper-file and
    unused-build-dependency-on-cdbs.
  * debian/patches/arm-neon.patch added to get ARM w/o Neon support.
    (LP: #1084852)
  * In debian/rules, avoid creating invalid subst expression in sed
    of DEBIAN* vars into files.
  * Remove unnecessary glib-header-single-entry.patch .
  * Add patches/struct-siginfo.patch to work around source bug in dereferencing
    internal stuct instead of public type.
  * New upstream version 23.0.1271.97
