pg_resetwal: Add --char-signedness option to change the default char signedness.
With the newly added option --char-signedness, pg_resetwal updates the
default char signedness flag in the controlfile. This option is
primarily intended for an upcoming patch that pg_upgrade supports
preserving the default char signedness during upgrades, and is not
meant for manual operation.
