script: use %n at the end of default tstamp_fmt

Since we are only outputting time-stamps when they differ
ending it with a newline, interferes with the output less.

script -T skip timstamps for same second

The result is much more readable if we only output the time-stamp
when it is at least 1s since last one.

script add -T fmt to print time-stamps

script -r is useful for recording time-stamps of when output

script add -T fmt to print time-stamps

script -r is useful for recording time-stamps of when output
happened. With -T, rather than playback the script in real-time
we simply print the time-stamps to show when the output happened.

This is very useful for example, for analyzing boot time activity.

If the fmt provided contains no % characters the default
%n@ %s [%Y-%m-%d %T]
is used, which lends itself to analysis by tools as well as humans.

script(1): work around slow reading child

If child is slow reading from its input, or even completely stops doing
the read, script(1) hangs in write(2) to the pts master waiting until
there is a space in the terminal discipline buffer. This also stops
handling any outer io, as well as child output.

Work around the problem by making pts master fd non-blocking, and be
prepared for short writes to it. The data to be written to master is
buffered in the tailq which is processed when select(2) detects that
master is ready for write.

Have script accept and ignore -e for Linux compat

In the util-linux version of script, it will always exit with succes.
Except when run with -e, in which case it will have the exit value of
the child. BSD Script already uses the child's exit value for its exit
value. Some config and other helper scripts depend on being able to
specify -e. Accept it for compatibility since we'll already to the
right thing, but otherwise we ignore it.
