[hwc] adopt COMMIT_PER_VBLANK functionality for each ouptut

The new TDM HWC API made us to provide the COMMIT_PER_VBLANK
functionality for each output independently.

An output tdm-backend provides the hwc capability for isn't
intended to be managed by tdm_layer_xxx functions, so there's
no need to have the COMMIT_PER_VBLANK functionality turned on
for such output, in contrast to outputs tdm-backend doesn't
provide the hwc capability for.

So now the COMMIT_PER_VBLANK functionality for the outputs
which don't support hwc behaves depend on a TDM_COMMIT_PER_VBLANK
env variable while outputs which support are always have this
functionality turned off (like they read TDM_COMMIT_PER_VBLANK as '0')

If a client adds the change_handler, we might be able to guess that
the client will watch the tdm client's fd and handle tdm events in
event loop. Otherwise, we CAN'T make sure if a client has event loop
which handles tdm events.

tdm-monitor: fix big message issue

Wayland has the 4096 message size restriction. So if tdm debug message
is bigger than that, the message will be devided.

remove buffers from commit_buffer_list when commit failed.

When pp, commit is the sync operation, cb_done() will be called at the line of
commit(). In this case, buffers will be freed in cb_done() before
LIST_FOR_EACH_ENTRY_SAFE(b, bb, &commit_buffer_list, commit_link) line done.
So commit_link should be deleted when freed.

When commit() successed, commit_link will be deleted twice. So we need to use
LIST_DELINIT instead of LIST_DEL
