The block_buffer was only ever written to but then never used in the
following code, making it unnecessary.
Fixes a "variable 'block_buffer' set but not used" compiler warning.
Video devices categorized by AVFoundation as
'AVCaptureDeviceTypeExternal(Unknown)' (like USB video streams) were not
recognized by libavdevice.

There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

<OS>_VERSION_MAX_ALLOWED indicates what version is available in
the SDK, while <OS>_VERSION_MIN_REQUIRED is the version we can
assume is available, i.e. similar to what is set with e.g.
-miphoneos-version-min on the command line.
This fixes build errors like these:
src/libavdevice/avfoundation.m:788:37: error: 'AVCaptureDeviceTypeContinuityCamera' is only available on macOS 14.0 or newer [-Werror,-Wunguarded-availability-new]
[deviceTypes addObject: AVCaptureDeviceTypeContinuityCamera];
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/AVFoundation.framework/Headers/AVCaptureDevice.h:551:38: note: 'AVCaptureDeviceTypeContinuityCamera' has been marked as being introduced in macOS 14.0 here, but the deployment target is macOS 13.0.0
AVF_EXPORT AVCaptureDeviceType const AVCaptureDeviceTypeContinuityCamera API_AVAILABLE(macos(14.0), ios(17.0), macCatalyst(17.0), tvos(17.0)) API_UNAVAILABLE(visionos) API_UNAVAILABLE(watchos);

Alternatively, we could use these more modern APIs, if enclosed
in suitable @available() checks.
Building with iOS platform, the compiler has a warning: "'devicesWithMediaType:' is deprecated: first deprecated in iOS 10.0 - Use AVCaptureDeviceDiscoverySession instead"

The problem here is that the lock ctx->frame_lock will become
an unreleased lock if the program returns at patched lines.

Apparently the changes from 3c9185bf3a
aren't enough; even with that in place, I got errors like this
when trying to build for iOS:
src/libavdevice/avfoundation.m:135:5: error:
'AVCaptureDeviceTransportControlsPlaybackMode' is unavailable: not
available on iOS
AVCaptureDeviceTransportControlsPlaybackMode observed_mode;
^
Fixes ticket #5654.
The linesize can be greater than the minimum required. This copies the
frame taking linesize into account.
