[Qemu-devel] [PATCH v7 28/39] qapi: Prefer 'struct' over 'type' in generator

[Eric Blake <eblake@redhat.com>]

Referring to "type" as both a meta-type (built-in, enum, union,
alternate, or struct) and a specific type (the name that the
schema uses for declaring structs) is confusing.  The confusion
is only made worse by the fact that the generator mostly already
refers to struct even when dealing with expr['type'].  This
commit changes the generator to consistently refer to it as
struct everywhere, plus a single back-compat tweak that allows
accepting the existing .json files as-is, so that the meat of
this change is separate from the mindless churn of that change.

Fix the testsuite fallout for error messages that change, and
in some cases, become more legible.  Improve comments to better
match our intentions where a struct (rather than any complex
type) is required.  Note that in some cases, an error message
now refers to 'struct' while the schema still refers to 'type';
that will be cleaned up in the later commit to the schema.

Signed-off-by: Eric Blake <eblake@redhat.com>

v7: enhance commit message; change check_struct() to refer to 'struct'
rather than 'type'; update a few more comments at this point (enough
fallout that I dropped Markus' R-b)
