* composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.

* composite.c (find_composition, composition_gstring_p)
(composition_reseat_it, find_automatic_composition):
* data.c (let_shadows_buffer_binding_p)
(let_shadows_global_binding_p, set_internal, make_blv)

(cons_to_signed, arith_driver):
* dbusbind.c (xd_in_read_queued_messages):
* dired.c (directory_files_internal, file_name_completion):
Use bool for booleans.
* dired.c (file_name_completion):
* process.h (fd_callback):
Omit int (actually boolean) argument.  It wasn't being used.
All uses changed.
* composite.h, lisp.h: Reflect above API changes.
