test-coroutine: add missing coroutine_fn annotations
...
Callers of coroutine_fn must be coroutine_fn themselves, or the call
must be within "if (qemu_in_coroutine())". Apply coroutine_fn to
functions where this holds.

test-coroutine: Add rwlock downgrade test
...
Test that downgrading an rwlock does not result in a failure to
schedule coroutines queued on the rwlock.
The diagram associated with test_co_rwlock_downgrade() describes the
intended behaviour, but what was observed previously corresponds to:
| c1 | c2 | c3 | c4 |
|--------+------------+------------+----------|
| rdlock | | | |
| yield | | | |
| | wrlock | | |
| | <queued> | | |
| | | rdlock | |
| | | <queued> | |
| | | | wrlock |
| | | | <queued> |
| unlock | | | |
| yield | | | |
| | <dequeued> | | |
| | downgrade | | |
| | ... | | |
| | unlock | | |
| | | <dequeued> | |
| | | <queued> | |
This results in a failure...
ERROR:../tests/test-coroutine.c:369:test_co_rwlock_downgrade: assertion failed: (c3_done)
Bail out! ERROR:../tests/test-coroutine.c:369:test_co_rwlock_downgrade: assertion failed: (c3_done)
...as a result of the c3 coroutine failing to run to completion.

tests: Move unit tests into a separate directory
...
The main tests directory still looks very crowded, and it's not
clear which files are part of a unit tests and which belong to
a different test subsystem. Let's clean up the mess and move the
unit tests to a separate directory.
