Use bool for boolean, focusing on headers.

* configure.ac (PTY_OPEN, GC_MARK_SECONDARY_STACK):
Use bool for boolean.
* lib-src/emacsclient.c, lib-src/etags.c, lib-src/hexl.c (FALSE, TRUE):
Remove.  All uses replaced with uncapitalized version.
* lib-src/emacsclient.c (message):
* lib-src/etags.c (make_tag, pfnote, consider_token, make_C_tag, lang_names):
* lib-src/hexl.c (un_flag, iso_flag, endian):
* lib-src/pop.c (pop_debug, pop_open, pop_multi_first, pop_multi_next)
(pop_trash):
Use bool for boolean.
* lib-src/etags.c (bool): Remove.
* lib-src/etags.c (globals, members, declarations, no_line_directive)
(no_duplicates): Use 'int' for boolean values that getopt requires
to be 'int'.  Formerly, these were 'bool' and 'bool' was 'int',
but we can no longer rely on this implementation.
* lib-src/pop.h (struct _popserver): Use bool_bf for boolean bit-fields.
