This patch allows bluetoothd to be run with Valgrind easily in debug
variants.
For userdebug and eng variants bluetoothd is renamed to bluetoothd-main
and bluetoothd acts a wrapper to launch it either with or without
Valgrind (this is decided by value of persist.sys.bluetooth.valgrind
property).
The patch fixes following clang warning:
...
profiles/audio/avdtp.c:3293:2: warning: Null pointer passed as an
argument to a 'nonnull' parameter
memcpy(cap->data, data, length);

Unregistering a SEP can trigger abort_cfm callback if some device is
connected thus we should free setups list after all endpoints are
unregistered to avoid error in abort_cfm due to non-existing setup.
In case audio IPC is suddenly disconnected (most likely due to crash of
mediaserver process) we should disconnect headset since it is no longer
associated with valid setup and cannot be used properly.
We should not try to neither auto-resume nor write when state is set to
NONE as this is case when we're being closed and it's ok do ignore
write request.
Using sysfs is causing problems due to filesystem permissions
(bluetoothd is running as bluetooth user) and bluetoothd already has
required capabilities for setting forward delay through ioctl.
Android uses bt-pan static interface in PAN profile. In server role
it uses it as bridge name. But current implementaion passes interface
names like bnep0, bnep1... Android Framework is unaware of this name
and unable to allocate IP address after profile connection setup.
Calling g_slist_remove within the callback of g_slist_foreach is very
inefficient as it has to iterate in the list twice to figure which
element to remove.
