Merge branch 'ps/parse-options-integers'

Update parse-options API to catch mistakes to pass address of an
integral variable of a wrong type/size.

* ps/parse-options-integers:
  parse-options: detect mismatches in integer signedness
  parse-options: introduce precision handling for `OPTION_UNSIGNED`
  parse-options: introduce precision handling for `OPTION_INTEGER`
  parse-options: rename `OPT_MAGNITUDE()` to `OPT_UNSIGNED()`
  parse-options: support unit factors in `OPT_INTEGER()`
  global: use designated initializers for options
  parse: fix off-by-one for minimum signed values
