  Configuration header that defines reasonable defaults at compile time.

  This allows compile-time configuration from the command line (typically via
  the build system) while still allowing the source to be built without any
  configuration.  The build system can define LILV_NO_DEFAULT_CONFIG to disable
  defaults, in which case it must define things like HAVE_FEATURE to enable
  features.  The design here ensures that compiler warnings or
  include-what-you-use will catch any mistakes.
