parse.y: Fix type declaration for group_name

The group_name grammar rule was incorrectly defined as
returning a type<val> which is an int.  It actually returns
a type<name> which is a char *.

Having group_name declared as val (int) and assigning a char * value
to it can lead to crashes on platforms where pointer size exceeds
size of int.

warnings during compilation:

 tests: Add unit tests for cgroup_compare_wildcard_procname()

This commit adds unit tests for cgroup_compare_wildcard_procname().

The following tests are included in this commit:

WildcardProcnameSimpleMatch - Compares an ignore rule with a
    wildcarded procname with a matching procname.  Expects true.

WildcardProcnameNoMatch - Compares an ignore rule with a wildcarded
    procname with a process that has a non-matching name.  Expects
    false.

ProcnameWildcard_AsteriskNoMatch - Compares a wildcard rule with
    a process name that doesn't match.  Expects false.

ProcnameWildcard_AsteriskMatch - Compares a wildcard rule with
    a process name that does match the rule.  Expects true.

ProcnameWildcard_AsteriskNoMatch2 - Compares a wildcard rule
    with a process name that is shorter than the rule and thus
    does not match.  Expects false.

ProcnameWildcard_AsteriskMatchExactly - Compares a wildcard
    rule with a process name that matches the rule exactly.
    Expects true.

ProcnameWildcard_NoAsteriskMatchExactly - Compares a rule
    with no wildcards with a process name that exactly matches
    the rule.  Expects false as the function exits early due
    to no asterisk in the rule.

5 years agocgrulesengd: Add wildcard matching for process names

cgrulesengd: Add wildcard matching for process names

This commit adds wildcard matching to process name
parsing in cgrulesengd.  Note that wildcard matching
works for standard rules and ignore rules.

For example, given the following rule in cgrules.conf

\#<user> <controllers> <destination>
tom:foo* memory FooCG/

Processes named 'foo', foo1', 'foo2', etc. would be moved
to the FooCG/ cgroup.  Processes named 'bar', 'fo', etc.
would not match this rule.
