The goal of this commit is to allow using ble.gatts_notify() at any time, even if the stack is not ready to send the notification right now. It also addresses the same issue for ble.gatts_indicate() and ble.gattc_write() (without response). In addition this commit fixes the case where the buffer passed to write-with-response wasn't copied, meaning it could be modified by the caller, affecting the in-progress write. The changes are: - gatts_notify/indicate will now run in the background if the ACL buffer is currently full, meaning that notify/indicate can be called at any time. - gattc_write(mode=0) (no response) will now allow for one outstanding write. - gattc_write(mode=1) (with response) will now copy the buffer so that it can't be modified by the caller while the write is in progress. All four paths also now track the buffer while the operation is in progress, which prevents the GC free'ing the buffer while it's still needed.
