Have all visible internal function names end with an underscore.

We haven't had a convention for naming internal functions in -internal.h
versus naming visible functions in include/**.h.  This patch changes every
function declared in a -internal.h file to be named ending with an
underscore.

Static function names are unaffected, since there's no risk of calling them
from outside Libevent.

This is an automatic conversion.  The script that produced was made by
running the following script over the output of

ctags --c-kinds=pf -o - *-internal.h |  cut -f 1 | sort| uniq

(GNU ctags was required.)

=====
#!/usr/bin/perl -w -n

use strict;

BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; }

chomp;

my $ident = $_;

next if ($ident =~ /_$/);
next if ($ident =~ /^TAILQ/);

my $better = "${ident}_";

print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n";

=== And then running the script below that it generated over all
=== the .c and .h files again
#!/usr/bin/perl -w -i -p
