test: add librpma_[init/fini]() unit tests

common: replace 'service' with 'port'

common: fix checking SPDX tag for files other then *.[ch]

Apart from the *.[ch] files there are only scripts in our repo now,
so all of them should have the same SPDX tag:
# SPDX-License-Identifier: $LICENSE

Only the LICENSE file has a different SPDX tag:
SPDX-License-Identifier: $LICENSE

examples: use the RPMA logging

common: fix checking file extensions in check-headers.h

Reorder checking files' extension according to number
of each kind of files in order to make it (hopefully) faster.
Currently there are:
- 103 *.c files - check them as 1st,
-  38 *.h files - check them as 2nd and
-  31 *.sh and *.cmake files - check them as 3rd.

The condition '[[ $(echo $file) =~ ".c" ]]' matches also all '*.c*' files
(for example all *.cmake or Dockerfile.centos) what is incorrect,
so let's fix checking all file extensions.

examples: add script for running examples on SoftRoCE

Add the 'examples/run-all-on-SoftRoCE.sh' script
for running all examples on SoftRoCE
and the 'test_softroce' make target to run it.

Add the 'verify' option to the 'config_softroce.sh' script
to check if SoftRoCE is already configured
and disable unneeded messages.

test: reorganization of the 'utils' unit test
