[PATCH v2 04/16] treewide: remove unnecessary cache.h inclusion from several sources

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

A number of files were apparently including cache.h solely to get
gettext.h.  By making those files explicitly include gettext.h, we can
already drop the include of cache.h in these files.  On top of that,
there were some files using cache.h that didn't need to for any reason.
Remove these unnecessary includes.
