For sched_setaffinity(), the EINVAL error that occurs
if 'cpusetsize' is smaller than the kernel CPU set size only
occurs with kernels before 2.6.9.

So on a direct syscall, the EINVAL could also occur for bufsiz < 0.
But at the moment, the error text is sufficiently vague
("bufsiz is not positive") that a change to the man page text
is probably not needed.
Simply continuing after an error is in most cases wrong,
and can lead to infinite loops (e.g., for EMFILE).
So handle an error by terminating.

Fill in some gaps in example code (variable declarations,
adding listening socket to epoll set).
Give variables more meaningful names.
Other minor changes.

Lines for these two characters were added in the previous patch,
but the actual characters were not included in the 4th column
of the table. This fixes that.

The page was phrased in a few places to describe the child as
holding the parent's memory until the child does an execve(2)
or an _exit(2). The latter case should really be the more
general process termimation (i.e., either _exit(2) or abnormal
termination).

(This mirrors the previous change to getdents.2)
Some file systems provide partial support for 'dt_type',
returning DT_UNKNOWN for cases they don't support.
Update the discussion of 'd_type' and DT_UNKNOWN to
support this.

The man page was not explicit about how the memory used by
the child is released back to the parent.

Clarify the description of some errors by giving examples
that produce the errors. (Text added for EAI_SERVICE and
EAI_SOCKTYPE.)
Also, add an error case for EAI_BADFLAGS.

In some cases, EINVAL can occur if 'optval' is invalid.
Note this, and point reader to an example in ip(7).

Move the shell session text that demonstrates the use of
the example program so that it precedes the actual
example program. This makes the page consistent with the
majority of other pages.

Add ".SS Program source" to clearly distinguish shell session and
descriptive text from actual program code.
