Subject: [PATCH] nbft: Add a simple unit test

A simple table dump utility, a set of real ACPI NBFT table files
and corresponding set of reference dumps, compared against each
other as part of the meson test run.

Please check the README file for details.

+This is a simple testcase to verify the NBFT parser output over a set
+of provided ACPI NBFT tables.
+
+The 'nbft-dump' test utility is a simple tool to print out all elements
+and nested arrays of the nbft_info structs, bearing only minimal logic.
+
+The 'tables' directory contains sample binary files taken from
+/sys/firmware/acpi/tables. The 'tables_bad' then contains experiments, older
+table revisions or malformed data to test the parser error path.
+
+The "diffs" directory contains reference output generated by the 'nbft-dump'
+utility that is being compared against actual testcase run output. Everytime
+'nbft-dump.c' is modified these reference output files need to be regenerated
+by calling `ninja -C .build nbft-diffs` over the configured meson project.
+
+The tests are typically ran as part of the standard `meson test -C .build`
+invocation.
