O-Subject: [RHEL-7.1 qemu-kvm PATCH v2 1/4] rename parse_enum_option to qapi_enum_parse and make it public
Bugzilla: 1087724

From: Peter Lieven <pl@kamp.de>

relaxing the license to LGPLv2+ is intentional.

(cherry picked from commit 9e7dac7c6c6003ad9d4aca0125f0278233fcf761)
Signed-off-by: Miroslav Rezanina <mrezanin@redhat.com>

Conflicts:
	blockdev.c
	qapi/Makefile.objs

Since detect-zeroes does not exist downstream, there was no
parse_enum_option() in blockdev.c and therefore no changes to that file
are necessary.
