* Start the ISO format flags at bit 0 instead of bit 1.
* Remove unnecessary _8601 from ISO format flag names to
avoid line wrapping and to ease readability.
* ISO timestamps have date-time-timzone in common, so move
the TIMEZONE flag to bit 2 causing all timestamp masks
to have the first three bits set and the last four bits
as timestamp 'options'.
* Change the 'SPACE' flag to a 'T' flag, because it makes
the code and comments more concise.
* Add common ISO timestamp masks.
* Implement the ISO timestamp masks in all applicable code
using the strxxx_iso() functions.

Earlier when typescript file failed new line after the error did not cause
carriage return. Here is an example how prompt> travels to wrong place:
prompt> script 0500-perms/typescript
Script started, file is 0500-perms/typescript

script(1) waits for empty slave FD (shell stdin) before it writes to
master. This feature has been intorduiced by 54c6611d6f
to avoid misbehavior when we need to send EOF to the shell.
Unfortunately, this feature has been used all time for all messages.
This is wrong because command in the session (or shell) may ignore
stdin at all and wait forever in busy loop is really bad idea. Test
case:
script /dev/null
tailf /etc/passwd
<enter>
<enter>
... script process taking 100% CPU.
This patch forces script to use empty-stave detection only when we
need to write EOF. The busy loop has been modified to use nanosleep
and it does not wait forever...

On s390 and other big endian machines, doinput() sends NUL instead of
EOF to the tty master. NUL does not even reach the slave, and it is
waiting for more data forever.
If STDIN is not a tty, the bug caused "^@" being into the log, and since
commit 032228c it also causes hang.

Specifying 'script --quiet ...' still produces the 'Script started'
message in the typescript file. The --quiet option implies that the

If both -f and -t are given, flush the timing fd on each write, similar
to the behavior on the script fd. This allows playback of still-running
sessions, and reduces the risk of ending up with empty timing files when
script(1) exits abnormally.

echo "ps uf" | script
does not work because script assume that stdin is terminal and
it does not forward EOF to the pty.
This patch:
* make non-tty use-case more robust (don't call tty ioclts to
non-tty file descriptors.
* send EOF (CTL('D') control char) to the master channel when
detected eof by read() on stdin
* wait for empty master and slave file descriptors to be sure that
we don't miss date for typescript. This is also necessary to be
sure that slave channel (shell) is completely initialized otherwise
EOF is ignored.
