Add tests that verify that overflow conditions behave appropriately.
Specifically:
* if overflow is continually flushed, then CQEs should arrive mostly in
order to prevent starvation of some completions
* if CQEs are dropped due to GFP_ATOMIC allocation failures it is
possible to terminate cleanly. This is not tested by default as it
requires debug kernel config, and also has system-wide effects

Dylan, this breaks -Werror build with clang-15.
```
cq-overflow.c:188:15: error: variable 'drop_count' set but not used [-Werror,-Wunused-but-set-variable]
unsigned int drop_count = 0;
^
1 error generated.
make[1]: *** [Makefile:210: cq-overflow.t] Error 1

Maybe you miss something that you forgot to use the value of @drop_count?
