25cad6ffcf ioat: clean up on exit in examples
Previously, the cleanup functions were only being called if there was an
error during initialization.

01b48b7c90 build: define a common Makefile clean command
Use $(CLEAN_C) throughout the Makefiles to clean up a consistent set of
generated files.

This also adds coverage files to the list of cleaned files.

the commands to build a .o from a .c, an app from objects and libraries,
and a library from objects, respectively.

668847e150 nvme: add max completions limit to I/O polling
nvme_ctrlr_process_io_completions() now takes a second parameter,
max_completions, to let the user limit the number of I/Os completed on
each poll.

If there are many I/Os waiting to be completed, the
nvme_ctrlr_process_io_completions() function could run for a long time
before returning control to the user, so the max_completions parameter
lets the user have more control of latency.

3677f46af8 build: allow make to work from any directory
Set SPDK_ROOT_DIR explicitly in each Makefile so that make from a
subdirectory will work (assuming all dependencies from the upper
directory have already been built).  This allows partial rebuilds of the
source tree, as well as building the unit tests without requiring DPDK.

before printing results.

55f3f20e3b nvme/perf: increase task pool size
This matches the size of the request pool and enables running with a
higher concurrency level.

Ideally, these limits should be calculated from the requested queue
depth and number of workers, but for now, just increase the hardcoded
limit.

binaries are regenerated if we make after touching a
