[PATCH v3 00/19] record btrace: non-stop, scheduler-locking, and ASNS

[Markus Metzger <markus dot t dot metzger at intel dot com>]

Changes to v2:
  - renamed the new scheduler-locking mode from "reverse" to "replay"
  - added to_record_will_replay target method to support the case where
    record full records during reverse execution
  - added support for scheduler-locking for all-stop targets

Changes to v1:
  - reworked non-stop test
  - changed the error string when trying to store registers while replaying
  - fixed all-stop/non-stop confusion in comments

This patch series adds support for non-stop mode to the record btrace target
and prepares for all-stop on top of non-stop (ASNS).

It adds a new scheduler-locking mode "reverse" for the current record btrace
behaviour of scheduler-locking during reverse/replay execution.

I tested this with the current all-stop and with Pedro's ASNS (by reverting
his disable patch).

The patch series can also be found on branch users/mmetzger/btrace-non-stop.
