wt-status: add helpers for printing wt-status lines

Browse Source 
Introduce status_printf{,_ln,_more} wrapper functions around
color_vfprintf() which take care of adding "#" to the beginning of
status lines automatically.  The semantics:

 - status_printf() is just like color_fprintf() but it adds a "# "
   at the beginning of each line of output;

 - status_printf_ln() is a convenience function that additionally
   adds "\n" at the end;

 - status_printf_more() is a variant of status_printf() used to
   continue lines that have already started.  It suppresses the "#" at
   the beginning of the first line.
