[mythtv] [PATCH] Mythfilldatabase tv_grab_uk_rt TBA

[steve at nexusuk.org]

The patch is available at:
    http://www.nexusuk.org/projects/pvr/patches/filldatabase_tba.php
It should fix all the problems people are having with tv_grab_uk_rt 
regrabbing the listings for all days every time mythfilldatabase runs.

This patch does two things:

* Prevents mythfilldatabase from grabbing the same day's listings 
  twice in the same session - this used to happen when it did the forced 
  regrab of any of the first three days and then those days failed the 
  checks to see if they were up to date. If the listings failed the check 
  the first time, grabbing them again isn't going to help.

* Adds a --dont-refresh-tba parameter which turns off the check for 
  programs marked as "to be announced" when using the tv_grab_uk_rt 
  grabber. This test is supposed to regrab the listings for days that 
  have programs that haven't been announced yet incase they've just been 
  announced. The problem is that some channels have these programmes in 
  them all the time, even on the current day's listings. The result is 
  that it grabs all the days every time it's run. With the slow speed of 
  the tv_grab_uk_rt grabber and the huge amount of data needed to be 
  grabbed to get all the days, this is a really bad thing. By specifying 
  --dont-refresh-tba you can turn off the check so it only grabs data for 
  empty days.
