meson support: create meson.build files

This commit contains the meson.build files necessary to build the
project and unit tests. The normal procedure is to run the command
'meson build' followed by ninja -C build. Additionally, service files
are copied to remove autoconf-style naming convention (they cannot be
  removed before autoconf files are removed).
