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.
