[PATCH 0/6] parse-options: add more precision handling

Extend precision handling to all options that currently blindly use an int pointer to access value variables. This allows the safe use of smaller and larger integer types.

Sign handling might be nice as well (especially for OPTION_COUNTUP), but is out of scope for this series.

  parse-options: add precision handling for PARSE_OPT_CMDMODE
  parse-options: add precision handling for OPTION_SET_INT
  parse-options: add precision handling for OPTION_BIT
  parse-options: add precision handling for OPTION_NEGBIT
  parse-options: add precision handling for OPTION_BITOP
  parse-options: add precision handling for OPTION_COUNTUP
