Fix DCP content font ID allocation to cope with DCPs that have multiple fonts

2023-10-15T07:10:18Z

with the same name in the same reel (#2600). Previously we had this id_for_font_in_reel() which would give an ID of N_font-ID. This means we got duplicate font IDs. Here we replace that method with FontAllocator, which gives an ID of N_font-ID for the first font and M_font-ID, where M is a number higher than the highest reel index. The idea is to support the required new IDs without breaking exisiting projects. There is some documentation of how it works in doc/design/fonts

This check used to be for asset channel count mismatches, then it was

changed to the active count, but I don't think it should be an error to have different active counts between assets of a single DCP.

Fix player audio, almost totally broken by a stupid mistake

in 78b2c650a9249cb7165d269b4378391d31e68e8b Following that commit 16 channel audio streams were being read as 6-channel, with unsurprising consequences.

Report the number of active channels in DCPs, not the number in the MXF.

Handle fonts for ccaps coming from DCP content (#2525).

Not dealing with them calls all sort of chaos as described in the bug report.

Fix _text_count for ccaps when there are multiple reels.

2023-05-12T20:11:06Z

Previously we would get a _text_count of 1 for open subs, no matter how many reels there were, but for ccaps the _text_count would increase with the number of tracks _and_ the number of reels.

Cleanup: more variable renames.
