941fab9023 [xcode] Circumvent ffmpeg 6 ALAC encoding problem 
The default ffmpeg ALAC encoder, "alac", requires fixed frames of size 4096,
but the Airplay 2 implementation feeds it with frames of size 352. Before
ffmpeg 6 this worked, but not any more. Seems a frame size check has been
added.

This commit doesn't fix this, but circumvents the ffmpeg error by modifying the
frame size that ffmpeg checks.

Fixes issue #1640

1379914857 [xcode] See if we can do without asking decoder for specific sample rate/channels 
We use filters now, so shouldn't be necessary.

request_sample_fmt and request_channel_layout was added with commit 73b2d08.

6f0fef6179 [spotify] Reintroduce libspotify support, change spotifyc to librespot-c 
Select use of either libspotify or librespot-c as streaming backend via config
option.

librespot-c (renamed/improved spotifyc) impl has the following:
- sync interface
- seek support
- honor bitrate config, set client and thread name
- use web access token with "streaming" scope for login
- fix issue with podcast playback

Also say goodbye to file-based Spotify login.

e8bdcd2365 [xcode] Use ffmpeg's "image2pipe" muxer instead of "image2" 
With ffmpeg 4.3 it seems image2 no longer works for non-file output, so use

b33e2665a1 [xcode] Hardcode png/jpeg pix formats (fix for #717) 
ffmpeg changed the behaviour of avcodec_default_get_format() so that it picks
AV_PIX_FMT_MONOBLACK instead of AV_PIX_FMT_RGB24 for the png encoder. That
makes the function of no use to us, so now the pix formats are just hardcoded
in the settings instead.

53780a7ef3 [xcode] Make sample rate + channels variable 
This change is preparation to use ffmpeg's resampling capabilities to keep local
audio in sync (by up/downsampling slightly). This requires that sample rates are
not fixed for a transcode profile.

Added benefit of this is that we don't need quite as many xcode profiles.
