(tzvalbuf_in_environ): New static var.
(init_editfns): Initialize these two static vars.
(Fencode_time): Don't assume arbitrary limit on EMACS_INT width.

instead, use xputenv+unsetenv to set and restore TZ.
(environbuf): Remove static var. All uses removed.
(Fset_time_zone_rule): Do not save TZ and environ;
no longer needed here.
(set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
Move to inside set_time_zone_rule; they don't need file scope any more.
(set_time_zone_rule): Maintain the TZ=value string separately.
(syms_of_editfns): Don't initialize initial_tz;
init_editfns now does it.

All uses replaced by 'kill' with a negative pid.
(SIGCHLD): Remove definition, as we now assume SIGCHLD.

* frame.c (make_frame): Use it. Adjust comment.
* buffer.c (candidate_buffer): New function.

Fixes: debbugs:12817
src/w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG

New function, containing part of the old call_process_kill.

This does not change call_process_kill's behavior.

race condition that could cause Emacs to lose track of a child.
