[age restriction] progress 12/n

- taler-offline-tool now handles extensions
  - command "extensions" added with subcommands "show" and "sign"
  - parses extensions from taler config
  - shows and signs of extensions and their configurations
  - creates signed set of configurations for upload
  - added test for retrieval of extension config

- simplified signature verification for extensions
  - remove per-extension signatures, also from DB schema
  - adjust prepared statements accordingly
  - adjust DB event handler for extensions
  - allow NULL for config for extension in DB schema
  - handler for /management/extensions adjusted to new datastructures

- changed test for TALER_denom_blind/TALER_denom_sign_blinded with and
  without TALER_AgeHash

- minor updates and various fixes
