BUG/MEDIUM: filters: Exec pre/post analysers only one time per filter

For each filter, pre and post callback functions must only be called one
time. To do so, when one of them is finished, the corresponding analyser bit
must be removed from pre_analyzers or post_analyzers bit field. It is only
an issue with pre-analyser callback functions if the corresponding analyser
yields. It may happens with lua action for instance. In this case, the
filters pre analyser callback function is unexpectedly called several times.

This patch should fix the issue #1263. It must be backported is all stable
versions.
