    build: Modernize build system a bit
    
    Use the tar-ustar option for AM_INIT_AUTOMAKE for better tarballs.
    Do not use AM_MAINTAINER_MODE as it is not recommended by automake
    developers.
    Stop using GNOME_COMMON_INIT as it is deprecated.
    Use LT_PREREQ & LT_INIT for libtool checks.
    Require intltool 0.40.6 to avoid various bugs.
    Do not use AC_ISC_POSIX, AC_HEADER_STDC as they shouldn't be needed on
    modern systems.
    Drop manual check for additional compiler flags.
