[PATCH 00/16] Header cleanups

Maintainer note: I dropped multiple changes from this series to avoid conflicts with other in-flight series, but two small conflicts remain. In order to merge with next, add the following declaration to abspath.h:

    /* Likewise, but path=="-" always yields "-" */
    char *prefix_filename_except_for_dash(const char *prefix, const char *path);

(from cache.h) and remove the entire conflicted region in cache.h. There is also a semantic conflict with seen; to fix, include abspath.h in the new file compat/fsmonitor/fsm-path-utils-linux.c.

This series picks up where en/header-cleanups leaves off and does more header cleanups, trying to reduce the number of files depending on cache.h. (There are still more that could be done, but again, this is a good chunk for now.)

Notes:

 * As I mentioned in my last series, Dscho's gitgitgadget is super helpful
   for a series like this.
 * As with my previous series (en/header-cleanup), I used the scripts at my
   header-cleanup-scripts branch
   [https://github.com/newren/git/commit/db81c8d7fb554b3edf04320e218bddeb98bb6194],
   and some tweaks thereof, repeatedly while making this series (though they
   are prone to produce both false positive and false negatives, so if you
   use them, only use them to generate hints about which files to look at).
