[PATCH v4 0/3] Reduce back and forth with target when threads have pending statuses

[Simon Marchi]

This is the v4 of patches 3 and 4 of this series:

  https://sourceware.org/pipermail/gdb-patches/2021-January/174786.html

The "better handling of 'S' packets" part of the series was already
merged.

Patch 1 is new, it adds a test to cover a case that didn't seem already
covered, that is running or attaching while the inferior is running.

Note that this series was developped and tested on top of these other
series/patches, so they can be considered prerequisites (applied in this
order):

  Fix detach + displaced-step regression + N bugs more
  https://sourceware.org/pipermail/gdb-patches/2021-January/175040.html

  Clear target async event handlers in wait method
  https://sourceware.org/pipermail/gdb-patches/2020-November/173633.html

  gdb: remove unneeded argument in check_multi_target_resumption
  https://sourceware.org/pipermail/gdb-patches/2021-January/175057.html

Simon Marchi (3):
  gdb/testsuite: add test for run/attach while program is running
  gdb: move commit_resume to process_stratum_target
  gdb: generalize commit_resume, avoid commit-resuming when threads have
    pending statuses
