2d30ab94c2 bluez5: account for codec internal delay in latency values 
Encoders and some decoders have additional internal latency that needs
to be accounted for.

This mostly matters for AAC (~40ms), as the other BT codecs have much
lower delays (~5ms).

5d7624001d Add spa/utils/endian.h 
This provides access to GNU C library-style endian and byteswap functions.

Windows doesn't provide pre-processor defines for endianness, but
all current Windows architectures (X32, X64, ARM) are little-endian.

934ab3036e treewide: use SPDX tags to specify copyright information 
SPDX tags make the licensing information easy to understand and clear,
and they are machine parseable.

00d51c3d31 bluez5: Rename codec API from *a2dp* to *media* 
The BlueZ Media1 interface will not only be used for A2DP but also for
LE Audio and code related can be shared.

b9baeeb587 bluez5: opus: react faster to too long packet queue 
React immediately to "bad" buffer level. Use smaller bitrate
increments/decrements.  Fix ABR timer increment for fragmented packets.
Handle actual bitrate being smaller than target during silence.

c1acb5168d bluez5: bump Opus max bitrates 
Limit bitrates to 2-2.5x Opus recommended "good quality", instead of
1.5x, which is safer quality-wise for CVBR.

Use smaller bitrate caps, as it's not necessary to use all bandwidth
available.

434cc6a90b bluez5: add Opus as a (Pipewire-specific) A2DP vendor codec 
Support Opus as A2DP vendor codec.

The specification for vendor A2DP codec is our Pipewire-specific one, so
it is compatible only with devices running Pipewire.
