[Qemu-devel] [PULL 05/40] block: Use warn_report() & friends to report warnings

[Markus Armbruster]

Calling error_report() in a function that takes an Error ** argument
is suspicious.  Convert a few that are actually warnings to
warn_report().

While there, split warnings consisting of multiple sentences to
conform to conventions spelled out in warn_report()'s contract, and
improve a rather useless warning in sheepdog.c.

Drop changes to "without an explicit read-only=on" warnings, because
there's a series removing them pending.  Also drop a cc: to a former
Sheepdog maintainer.
