Add support for custom xref queries
The custom queries are configured in rebar.config via the tuple
{xref_queries, [{query(), query_result()},...]}. The implementation
passes the query() string to xref:q and compares the return value with
query_result(). It will result in an error if they do not match.
The following configuration, for example, is the same as running the
xref check undefined_function_calls. It additionally filters
ejabberd_logger:*_msg/4 from the result as these functions are generated
on execution by ejabberd and not available at compile time.
{xref_queries, [{"(XC - UC) || (XU - X - B -
(\"ejabberd_logger\":\".*_msg\"/\"4\"))",[]}]}.
This patch also modifies the build process of this package by running a
custom query instead of doing a diff against a static xref_warning file.
