Alfonso Siciliano 263660c061 bsddialog: import version 0.1 
Import bsddialog 0.1 Utility and Library, fully refatorized, API stable,
manuals completed, easier to maintain and improve.

Update deps for new API:
add mixedgauge consts, delete __DECONST and add bsddialog_geterror()
info to avoid silent errors

* tzsetup
* kbdmap
* distextract
