[PATCH v1 0/6] globals: clean up some global usages

Hi,

This patchset moves a few of the configuration parsing functions around so that they live in the source file which uses the variables that are initialized through those functions. This allows the variables involved to be `static` rather than global variables.

Additionally, a global which is only written to is removed (`core_compression_level`), a file-local variable declared `extern` is now `static`, and explicit `0` initialization of globals is removed.

In the course of making this patch, I found a number of other global variables which could be moved into being static if more configuration parsing functions were created and moved to the relevant file instead of being parsed as part of, say, "all `core.*` settings" in a single function. If wanted, I can prepare a patchset for these as well (or provide the list for discussion of how best to proceed, but it is currently just stored in a WIP commit I have locally as comments on each variable).

Thanks,

--Ben
