David Brownell <david-b@pacbell.net>:
Extend the internal JTAG event handlers to cover enable/disable,
and use those events to make sure that targets get "examined" if
they were disabled when the scan chain was first set up:
- Remove "enum jtag_tap_event", merge with "enum jtag_event",
so C code can now listen for TAP enable/disable events.
- Report those events so they can trigger callbacks.
- During startup, make target_examine() register a handler to
catch ENABLE events for any then-disabled targets.
This fixes bugs like "can't halt target after enabling its TAP".
One class of unresolved bugs: if the target has an ETM hooked
up to an ETB, nothing activates the ETB. But starting up the
ETM without access to the ETB registers fails...
