Patch 1 fixes a segfault when trying to add a rule referring to a map
and adds a relevant test case. Patch 2 fixes for wrong format of map
values, this is already covered by existing tests. Patch 3 merely
improves versatility of tests/monitor/run-tests.sh a bit.
Phil Sutter (3):
monitor: Do not decompose non-anonymous sets
monitor: Fix for use after free when printing map elements
tests: monitor: Support running individual test cases

They have been decomposed already, trying to do that again causes a
segfault. This is a similar fix as in commit 8ecb885589591 ("src:
restore --echo with anonymous sets").

When populating the dummy set, 'data' field must be cloned just like
'key' field.
Fixes: 343a51702656a ("src: store expr, not dtype to track data in sets")
