v0.12.13
the old implementaion of filter_grep uses the system regex.h engine instead of libonigmo which is the default solution. This patch deprecate the usage of regex.h. note: this plugin should behave as Fluentd grep plugin, it needs to be fixed to work with rules in 'pipe' mode instead of a simple ACL.
