Changed error messages: now don't print anything below main() unless the new

Browse Source 
option --show-below-main is on.  It's on by default.  It also affects
suppressions generated with --gen-suppressions=yes.  Updated reg tests
accordingly.

Also updated docs for this.  And added some missing command-line args to docs.
Also compartmentalised the options a little in the docs, and rearranged the
order of options in the usage message, in anticipation of a bigger
rearrangement that will be necessary soon -- to distinguish options used by all
skins from those used by error-checking skins, to skin-specific ones.

</li><br><p>
<li><code>--logfile-fd=&lt;number&gt;</code> [default: 2, stderr]
<p>Specifies that Valgrind should send all of its
messages to the specified file descriptor. The default, 2, is
the standard error channel (stderr). Note that this may
interfere with the client's own use of stderr.
</li><br><p>
<li><code>--logfile=&lt;filename&gt;</code>
<p>Specifies that Valgrind should send all of its
messages to the specified file. In fact, the file name used
is created by concatenating the text <code>filename</code>,
".pid" and the process ID, so as to create a file per process.
The specified file name may not be the empty string.
</li><br><p>
<li><code>--logsocket=&lt;ip-address:port-number&gt;</code>
<p>Specifies that Valgrind should send all of its messages to
the specified port at the specified IP address. The port may be
omitted, in which case port 1500 is used. If a connection
cannot be made to the specified socket, valgrind falls back to
writing output to the standard error (stderr). This option is
intended to be used in conjunction with the
<code>valgrind-listener</code> program. For further details,
see section <a href="#core-comment">2.3</a>.

not Cachegrind.

This option is particularly useful with C++ programs, as it prints out
the suppressions with mangled names, as required.

Note that the suppressions printed are as specific as possible. You
may want to common up similar ones, eg. by adding wildcards to function
names. Also, sometimes two different errors are suppressed by the same
suppression, in which case Valgrind will output the suppression more than
once, but you only need to have one copy in your suppression file (but
having more than one won't cause problems). Also, the suppression
name is given as <code>&lt;insert a suppression name here&gt;</code>;
