Here's a fix adding the missing headers to pg_combinebackup, and fixing

I've done some basic manual testing today - I plan to test this a bit
more tomorrow, and I'll also look at integrating this into the existing
tests.
Here's a bit more complete / cleaned patch, adding the testing changes
in separate parts.
0001 adds the missing headers / fixes the now-accessible code a bit
0002 adds the --copy option for consistency with pg_upgrade
This looks good.
0003 adds the PG_TEST_PG_COMBINEBACKUP_MODE, so that we can override the
copy method for tests
I had imagined that we combine PG_TEST_PG_UPGRADE_MODE and this new one
into one setting. But maybe that's something to consider with less time
pressure for PG18.

Right, that was one of the reasons.
0004 tweaks two of the Cirrus CI tasks to use --clone/--copy-file-range
I'm not sure about 0004 - I initially did this mostly to check we have
the right headers on other platforms, but not sure we want to actually
do this. Or maybe we want to test a different combination (e.g. also
test the --clone on Linux)?
It's tricky to find the right balance here. We had to figure this out
for pg_upgrade as well. I think your solution is good, and we should
also add test coverage for pg_upgrade --copy-file-range in the same
place, I think.
