#2087: Clean up US cable frequency tables

Changes (by sphery <mtdean at thirdcontact.com>):
* type: task => patch
* summary: Clean up NTSC cable frequency tables => Clean up US cable
frequency tables
Comment:
Added patches for digital frequency tables. My recommendation is to apply
the following patches before 0.20 release (in the order specified):
mythtv-ntsc_cable-fix_t_band.patch [[BR]]
mythtv-ntsc_irc-t_band_to_match_standard.patch [[BR]]
mythtv-digital_cable-fix_standard.patch [[BR]]
mythtv-digital_cable-fix_t_band-after_fix_standard.patch [[BR]]
mythtv-digital_cable_hrc_irc-fix.patch [[BR]]
mythtv-digital_cable_hrc_irc-fix_high.patch [[BR]]
mythtv-digital_cable-scanfrequencytable_labels.patch [[BR]]
Doing so will only fix the values that will not work and does not remove
any channels (even where they're not defined for the frequency table).
Once these patches are applied, milestone can be changed to 0.21.
After 0.20, we can do the more experimental changes, such as:
* removing channels (i.e. channel 1 in standard and T-band channels in
HRC/IRC), if desired
* finetuning frequencies (i.e. using the 6.0003MHz step for HRC and
adjusting IRC by 12.5kHz (or 25kHz for 42, 98, and 99)
* possibly creating a new frequency table to allow for differentiation
between positive and negative offsets in the
radionavigation/radiocommunications bands for channels in the standard
frequency tables
These patches may require digital users to rescan channels (depending on
which frequencies their cable companies use), but likely no more so than
[10593] did.
