ble://: use a paired link - #48

Conversation
A board started with bledev pairing refuses an unpaired computer's first write (ATT 0x05). The transport now pairs just works when that happens, which covers a board without a display, and says how to pair once when the board wants a passkey (python -m bledev.bleak pair NAME, or Windows Settings). The password is optional: a board that pairing unlocks opens on the first line without asking. A link that falls at the first write on a computer paired with the board is explained as a lost bond, with the unpair step.
A write without response to a characteristic the board protects is dropped silently, so the unpaired case never surfaced. When just works isn't enough (the board wants a passkey), unpair again rather than leave a pairing that only gets in the way, and say how to pair once.

…eading Nine version sites now say 0.0.8 and check_versions.py passes. The curated Unreleased notes become the v0.0.8 section, with a line for BLE pairing (#48), and the bot's commit list is dropped.

ble://over a paired link, for boards running bledev withpairing=(PyDevices/pydevices#88). Stacked on #47 (ble-transport); merge that first.python -m bledev.bleak pair NAMEor Windows Settings.Checked on the LCD-7 from Windows: with the bond from a passkey pairing and no password set,
execand a 20 KBput/get, byte for byte. Against a just-works board with a password: mpftp paired by itself and logged in; a wrong password was still refused. Against a passkey board with the computer unpaired: the message, and Windows held no pairing afterwards. Unit tests cover each path, and disabling the pairing call turns three of them red.
