pselect: new module
* lib/sys_select.in.h: Include <signal.h>, for 'sigset_t'.
(pselect): New decls.
* m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Require AC_C_RESTRICT,
since the standard pselect decl uses 'restrict'.
(gl_SYS_SELECT_H_DEFAULTS): Add defaults for GNULIB_PSELECT,
HAVE_PSELECT, REPLACE_PSELECT.
* modules/sys_select (sys/select.h): Substitute GNULIB_PSELECT,
HAVE_PSELECT, REPLACE_PSELECT.
* lib/pselect.c, m4/pselect.m4, modules/pselect: New files.
