Use bool for boolean in textprop.c, undo.c

* src/textprop.c (soft, hard): Now constants instead of macros.
(validate_plist): Rewrite to avoid need for boolean local.

(copy_text_properties):
* src/tparam.c (tparam1):
* src/undo.c (record_change, record_property_change)
(syms_of_undo):
Use 'true' and 'false' for booleans.
