libidn: upgrade to 0.6.14(GPLv2), and 1.19 (GPLv3)

libidn changed to GPLv3 since 2007 (its 1.0 release), so this upgrade includes two:

0.6.14 (GPLv2):
  - change SRC_URI as original doesn't work
  - remove original do_configure_prepend, which doesn't make any sense when inheriting
    autotools
  - this version includes a local copy of AC_USE_SYSTEM_EXTENSIONS which conflicts with
    latest autoconf. Actually it's not necessary and remove all references to local version

1.19 (GPLv3):
  - split a new package 'idn' for command line tools, which are licensed under GPLv3.
    keep other bits in libidn licensed under LGPLv2.1
