Subject: [PATCH 017/268] block: Add block-specific QDict header

RH-Author: Markus Armbruster <armbru@redhat.com>

Patchwork-id: 80736

O-Subject: [RHEL-7.6 qemu-kvm-rhev PATCH 08/23] block: Add block-specific QDict header

Bugzilla: 1557995

RH-Acked-by: Max Reitz <mreitz@redhat.com>

RH-Acked-by: Jeffrey Cody <jcody@redhat.com>

RH-Acked-by: Kevin Wolf <kwolf@redhat.com>

From: Max Reitz <mreitz@redhat.com>

There are numerous QDict functions that have been introduced for and are

used only by the block layer.  Move their declarations into an own

header file to reflect that.

While qdict_extract_subqdict() is in fact used outside of the block

layer (in util/qemu-config.c), it is still a function related very

closely to how the block layer works with nested QDicts, namely by

sometimes flattening them.  Therefore, its declaration is put into this

header as well and util/qemu-config.c includes it with a comment stating

exactly which function it needs.
