The check-file-access.pl script is used to match access list
generated by virtestmock against whitelisted rules stored in
file_access_whitelist.txt. So far the rules are in form:
$path: $progname: $testname
This is not sufficient because the rule does not take into
account 'action' that caused $path to appear in the list of
accessed files. After this commit the rule can be in new form:
$path: $action: $progname: $testname
where $action is one from ("open", "fopen", "access", "stat",
"lstat", "connect"). This way the white list can be fine tuned to
allow say access() but not connect().
