[Qemu-devel] [PATCH] Modify qemu-img can not create local filename contain ":"

[Jun Li <junmuzi@gmail.com>]

Such as how to visit glusterfs:
file=gluster://1.2.3.4/testvol/a.img
file=gluster+tcp://1.2.3.4/testvol/a.img
file=gluster+tcp://1.2.3.4:24007/testvol/dir/a.img
file=gluster+tcp://[1:2:3:4:5:6:7:8]/testvol/dir/a.img
file=gluster+tcp://[1:2:3:4:5:6:7:8]:24007/testvol/dir/a.img
file=gluster+tcp://server.domain.com:24007/testvol/dir/a.img
file=gluster+rdma://1.2.3.4:24007/testvol/a.img
----
So if only the path contain "://", the path maybe contain a protocol. So use
strstr() to replace func strcspn().
