include/asterisk/time.h: Renamed global declaration:tv

Browse Source 
Renamed global declaration:tv to dummy_tv_var_for_types,
which would oltherwise cause 'shadow' warnings when 'tv'
was declared as a local variable elsewhere.

Added comment to note that dummy_tv_var_for_types is never
really exported and only used as a place holder.
