applet.interface.jtag_probe: fix race condition in scan_xr().

applet.interface.jtag_probe: don't track IR offsets. NFCI.

Per-TAP IR offsets are redundant, pointless, and complicate the logic
of specifying IR lengths manually.

applet.interface.jtag_probe: improve TAP selection logic.

* Require --tap-index option if more than one TAP is found.
Before this commit, TAP #0 was implicitly chosen.
* Extract redundant error handling code into select_tap().
* Convert logger errors into exceptions where appropriate.

applet.interface.jtag_probe: remove read_dr(idempotent=) argument.

Before this commit, this unused option had to be threaded through
a lot of unrelated code, which polluted interfaces. Moreover, since
commit 42144aa6, it is also worse than useless, because scan_dr()
does the exact same thing more safely (it does not rely on provided
DR length).

applet.interface.jtag_probe: remove scan_dr(zero_ok=) argument.

Before this commit, this option used only in enumerate-ir had to be
threaded through a lot of unrelated code, which polluted interfaces
and made the logic hard to understand.

Also, tighten the post-conditions on scan_xr_length() such that it
always requires a valid scan result (finite non-zero length).

applet.interface.jtag_probe: move XR scan limits to JTAGProbeInterface.

Before this commit, these rarely useful options had to be threaded
through a lot of unrelated code, which polluted interfaces and was
done quite inconsistently.

Also, do not call add_run_arguments() from add_run_tap_arguments().
This was inconsistent with our conventions and required an `access`
argument in add_run_tap_arguments() that was otherwise unnecessary.

applet.interface.jtag_probe: reliably detect overlong XR scans.

applet.interface.jtag_probe: clarify enumerate-ir documentation.

Also, lower log level for DR[?] to WARN since it is as noncompliant
as DR[0] and neither of these results usually indicates a problem.

cli: make horrifying formatting regexps even more horrifying.

Before this commit, lists weren't formatted, which was quite ugly
with list items longer than ~70 characters. After this commit, list
items are reflowed and their indentation is normalized.
