This creates a new fsmonitor-ll.h with most of the functions from fsmonitor.h, though it leaves three inline functions where they were. Two-thirds of the files that previously included fsmonitor.h did not need those three inline functions or the six extra includes those inline functions required, so this allows them to only include the lower level header. Diff best viewed with `--color-moved`. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
