kbx: Implement keybox_lock for use by gpg.

Browse source 
* kbx/keybox-defs.h: Include dotlock.h and logging.h.
(CONST_KB_NAME): Remove.  Replace usage by KB_NAME.
(struct keybox_name): Add field "lockhd".
* kbx/keybox-init.c (keybox_register_file): Init LOCKHD.
(keybox_lock): Chnage to return gpg_error_t.  Implement locking.
--

The keybox locking for gpg was not implemented - This needs to be
fixed of course.
