O-Subject: [RHEL8.0 qemu-kvm PATCH v7 03/10] memory, exec: Expose all memory block related flags.
Bugzilla: 1539285

From: Junyan He <junyan.he@intel.com>
We need to use these flags in other files rather than just in exec.c,
For example, RAM_SHARED should be used when create a ram block from file.
We expose them the exec/memory.h
