Convert event-config.h macros to avoid reserved identifiers

C reserves all identifiers beginning with an underscore for system
use.  But we had been mangling our autoconf identifiers with the
prefix "_EVENT_" to avoid conflict with other programs.

Instead, we will now use the prefix "EVENT__".  With any luck, the
double-underscore will still hint "here be dragons" to anybody
tempted to think that event-config.h is a stable api.

This is an automatically generated patch.  The script that produced
it was made by running this script over config.h.in:

=====

#!/usr/bin/perl -w

# Run this on config.h.in

use strict;

my %macros = ();

while (<>) {
    if (/^# *undef +([A-Za-z0-9_]+)/) {
	$macros{$1} = 1;
    }
}

print "#!/usr/bin/perl -w -i -p\n\n";
for my $k (sort keys %macros) {
    print "s/(?<![A-Za-z0-9_])_EVENT_$k(?![A-Za-z0-9_])/EVENT__$k/g;\n";
}

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