Reset SIGCHLD handler to SIG_DFL.

If run with "-c", both child and parent script processes will handle
SIGCHLD resulting in a possible duplicate "Script done" line in the
output.  This fixes bin/54514.

1. restore the previous finish() logic to make:
	script -e -c /usr/bin/true
	script -e -c /usr/bin/false
   exit with the proper exit code.
2. handle system return value correctly (nabijaczleweli)
3. factor out the conversion of wait status -> shell return code.

script: declare dooutput as __dead

This fixes the Clang build, which failed with:

usr.bin/script/script.c:255:1: error:
    function 'dooutput' could be declared with attribute 'noreturn'
    [-Werror,-Wmissing-noreturn]

PR/56254: RVP: Don't call non-async-signal-safe functions from signal handlers.
Establish a non-restart signal handler to avoid blocking in long I/Os.

dooutput can return if finish() does not find a chile process.

If -e is specified exit with the exit status of the child process in
a shell-like format (nabijaczleweli)

Unlike done() childwait() returns, found by clang.

PR/55551 Soumendra Ganguly: Simplify tcgetattr error handling.

PR/55548: Soumendra Ganguly: Since isatty(3) is implemented using
tcgetattr(3), call it directly to avoid calling it twice. This
makes error handling more precise. Also don't call err(3) when
tcsetattr(3) fails.

remove trailing whitespace

PR/55531: Soumendra Ganguly:
- add more error handling
- handle -p when not a terminal
- call termreset() before printing script done, so that it is printed correctly

Also:
- use ssize_t/size_t instead of int
- use EXIT_SUCCESS/EXIT_FAILURE
- check result of fork() against -1

PR/55529: Soumendra Ganguly: configure the terminal in raw mode during
playback so that output postprocessing is not done and playback of programs
using curses does not appear corrupted.

Fix PR: 26363: script core dumps on incorrect input files.

This patch virtually re-writes the playback code and contains
improvements (mainly the dependency upon BUFSIZ being the same
size as it was wrote at).

Patches provided by Joel Baker in PR 22365, verified by myself.

Add an alternate "typescript mode" that contains timestamps and other
data interleaved between chunks of actual output (and input), and
teach script how to read the new format so that sessions can be played
back at "proper" time.

don't use union wait; an int is good enough.
