[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
