Unit tests (#6)

* Initial commit of unit tests [WIP]

* Address shortcomings and bugs flushed out by unit tests

* Enable unit testing in CI workflow

* Enable verbose ctests

* Handle lack of __FILE_NAME__ define

* Only podman support `run --arch` argument

* Skip docker build testing if CI system cannot pull an image

* Remove errant call to puts()

* Identify local repo user

* Fix missing xmllint

* NULL terminate arrays

* Fix filename assignment in is_url mode

* Break loop when expected lines are exhausted

* strcmp_array expects NULL terminated array. Iterating by size in this case passes NULL to strcmp leading to an invalid read

* Remove debug printf statements

* Disable a few warnings for tests

* Workaround for ctest junit xml truncation

* Update checkout@v4

* Prevent false-positive result

* Return zero on error

* Fix strlist_remove function

* Value argument can be constant

* Fix test to match changes to startswith and endswith

* Add test_ini.c

* Fix redaction code to accept NULL pointers in array

* And let the caller specify the length of the array of strings to redact.

* Redactions now occur directly on authentication strings rather than their command line arguments

* Fix BUILD_TESTING_DEBUG

* Adds missing -D argument
