Merge branch 'sb/parseopt-boolean-removal'

Convert most uses of OPT_BOOLEAN/OPTION_BOOLEAN that can use
OPT_BOOL/OPTION_BOOLEAN which have much saner semantics, and turn
remaining ones into OPT_SET_INT, OPT_COUNTUP, etc. as necessary.

* sb/parseopt-boolean-removal:
  revert: use the OPT_CMDMODE for parsing, reducing code
  checkout-index: fix negations of even numbers of -n
  config parsing options: allow one flag multiple times
  hash-object: replace stdin parsing OPT_BOOLEAN by OPT_COUNTUP
  branch, commit, name-rev: ease up boolean conditions
  checkout: remove superfluous local variable
  log, format-patch: parsing uses OPT__QUIET
  Replace deprecated OPT_BOOLEAN by OPT_BOOL
  Remove deprecated OPTION_BOOLEAN for parsing arguments
