[v3,00/23] tests: Compile-time format string checking for libqtest.h

This is a reboot of "[PATCH 0/9] tests: Clean up around qmp() and
hmp()" I sent about a year ago.  Back then, Eric folded it into his
"Clean up around qmp() and hmp()" series, which stalled after v4.

My reboot tries to avoid that fate by reducing mission creep.  There
are plenty of good ideas in Eric's series we should mine some day, but
today is not that day.

v3:
* Reordered to reduce churn: PATCH 04 was 21, 05 was 01
* PATCH 04: Instead of open coding the *_discard_response() in tests,
  add macros with a TODO [Thomas]
* PATCH 05: Comments tweaked again, ripple effect on PATCH 06+14
* PATCH 14: Quoting bug and commit message typo fixed [Eric]
* PATCH 19: Missing attribute supplied [Eric]
* PATCH 20: Whitespace cleanup [Eric]
* PATCH 22: Commit message typo fixed [Eric]
* PATCH 23: Commit message improved [Eric]
v2:
* PATCH 01: Comments tweaked, ripple effect on PATCH 05+13
* PATCH 05: Commit message improved [Thomas]
* PATCH 06: Style fix [Philippe]
* PATCH 16+17: Silence a warning
* PATCH 21-23: New
