Hello Maintainers
This patch series handles code implementation for mandatory features of Volume Offset Control Service.
Implementation of following features have been handled in this patch series
- Volume Offset Control Service
- Volume Offset State Characteristic (Read, Notify)
- Audio Location Characteristic (Read)
- Volume Offset Control Point Characteristic (Write)
- Audio Output Description Characteristic (Read)
- Set Volume Offset
Reference Document:
- Code implementation is based on VOCS_v1.0.pdf
- Testing is done using PTS in reference to VOCS.TS.p1.pdf
- The verdict is PASS for all mandatory test cases.
Thank you in advance for your review.
Warm Regards
Nitin Jadhav

- This adds implementation for VOCS service and characteristics
- Implementation based on VOCS_v1.0.pdf specification
- Tested using PTS with reference to VOCS.TS.p1.pdf

v2: Corrected prefixs and cosmetic changes (Luiz Augusto von Dentz)
v3: Commit message modified and fixed long line length warning (Paul
Menzel)
v4: Used BIT macro to set bit of audio location macros (Luiz Augusto von Dentz)
v5: Resolved Scan Build warning (tedd_an/ScanBuild)

Fixed the following issue observed during PTS testing
- Specified Upper and Lower Limit for Volume offset
- Corrected the number of handles for VOCS
- VOCS is made as included service of VCS
(VOCS is secondary service and VSC is primary service)

I'm seeing a crash on BlueZ master branch
6b9d167034b741605c3186e78e9742dda8e28e08 with this patch, when trying
pair LE Audio TWS earbuds, with ControllerMode=le and experimental
features enabled in config and sound server with BAP support running.
It seems to crash reproducibly here during pairing. Also trying to
connect to previously paired BlueZ<->BlueZ seems to crash.
Reverting commit d2d2d12f59d65002c4a671a5af1837f295181142
("shared/vcp.c: Make VOCS as an included service of VCS") makes it to
not crash any more. Didn't try to look so far into detail if it's
directly related to this patch, but something in VCP might not be quite
right.
