[Qemu-devel] [PATCH v6 00/29] Preliminary libqtest cleanups

[Eric Blake <eblake@redhat.com>]

Markus gave some good advice on my 'v4: Clean up around qmp() and hmp()'
series [1], but Paolo made the suggestion on v5 [2] that we are probably
better off avoiding dependence on a magic global variable, rather than
making such dependence even more prominent.  So, this round of patches
starts to head in the direction of more explicit use of a QTestState
object - particularly in all tests that have more than one test state
active at a given time.  There is still more work to do (patch 28 shows
how many tests still depend on global_qtest), and I'd still like to do
even more renaming (for example, rather than having qtest_inb(s, addr)
and inb(addr), I'd rather have a single inb(s, addr) once I get rid of
all dependence on global_qtest, but this series was getting long
enough that I want to get review started on the earlier parts that
might as well go in the tree now rather than waiting for the whole
conversion series to be complete.  (Or, by posting this alternative
that goes the opposite direction from v5, we may decide that depending
on global_qtest is not so bad after all, and just go with v5 instead
of this version.)

There's still more libqtest cleanups in my queue, in particular all
the work around making qmp("...") friendlier to use and compatible
with gcc -Wformat checking, but we'll take it one step at a time.
