The last several commits were geared at replacing the include of cache.h
in strbuf.c with an include of git-compat-util.h. Unfortunately, I had
to drop a patch moving some functions from cache.h to object-name.h, due
to excessive conflicts with other in-flight topics.
However, even without that patch, the series of patches so far allows us
to modify a number of C files to replace an include of cache.h with
git-compat-util.h. Do that to reduce our dependencies.
(If we could have kept our object-name.h patch in this series, it would
have also let us reduce the includes in checkout.c and fmt-merge-msg.c
in addition to strbuf.c).
Just to ensure that nothing else was bringing in cache.h, all of the
affected files have been checked to ensure that
gcc -E -I. $SOURCE_FILE | grep '"cache.h"'
found no hits and that
make DEVELOPER=1 ${OBJECT_FILE_FOR_SOURCE_FILE}
successfully compiles without warnings.
