[Tile-serving] [openstreetmap/mod_tile] memory consumption (#181)

[Roland Bosa]

@hummeltech I'll pull out the commit for the `strntok_r` code into a separate branch and will mention it/create a PR in the new issue.

Regarding the memory consumption in general: I've been experimenting with `tcmalloc` a little and it seems to have slightly smaller footprint than `jemalloc`. But for some reason yet unknown, both have deteriorated into `glib`-similar consumption issues... I was expecting ~3GB for `jemalloc`/`tcmalloc` compared to ~17GB for `glib`. I'm seeing >10GB for either allocator. Something is different than my setup of a few days ago, hopefully I can figure out what it is.

I've committed a [few traces](https://github.com/openstreetmap/mod_tile/compare/master...rolandbosa:mod_tile:use_jemalloc) and hope to visualize them to get a better idea of what's going on.
