[PATCH for-8.2 0/4] qapi/migration: Dedup migration parameter objects and fix tls-authz crash

[Peter Xu <peterx@redhat.com>]

Patch 1 fixes the tls-authz crashing when someone specifies "null"
parameter for tls-authz.

Patch 2 added a test case for all three tls-auth parameters specifying
"null" to make sure nothing will crash ever with 'null' passed into it.

Patch 3-4 are the proposed patches to deduplicate the three migration
parameter objects in qapi/migration.json.  Note that in this version (patch
3) we used 'str' to replace 'StrOrNull' for tls-* parameters to make then
deduplicate-able.

Please review, thanks.
