[pmg-devel] [PATCH v6 pmg-log-tracker/pmg-api] rewrite in rust

[Mira Limbeck]

pmg-log-tracker has been rewritten in Rust. Functionality is the same
with before queue filter support added in patch 3.

Patch 4 adds some (limited) tests. Tests can be run with 'cargo test'.

There's one change regarding the interface. In addition to the short
versions of arguments also long versions exist.

v6:
 - added before queue filter support
 - added some (limited) tests
 - add pmg-smtp-filter ID to SMTP reply on reject
v3:
 - benchmarks using /usr/bin/time instead of zsh built-in

v2:
 - patch to remove src/pmg-log-tracker.c and src/Makefile
 - added simple benchmarks

Regarding the version, how do you want to handle it? Keep the Cargo.toml
version in sync with the package version (major, minor)?

Some simple benchmarks: (32 syslog files (syslog to syslog.31.gz))
