Convert all include-guard macros to avoid reserved identifiers.

In C, we technically aren't supposed to define our own things that
start with an underscore.

This is a purely machine-generated commit.  First, I ran this script
on all the headers in src/{common,or,test,tools/*}/*.h :
==============================

use strict;

my %macros = ();
my %skipped = ();
FILE: for my $fn (@ARGV) {
    my $f = $fn;
    if ($fn !~ /^\.\//) {
	$f = "./$fn";
    }
    $skipped{$fn} = 0;
    open(F, $fn);
    while (<F>) {
	if (/^#ifndef ([A-Za-z0-9_]+)/) {
	    $macros{$fn} = $1;
	    next FILE;
	}
    }
}

print "#!/usr/bin/perl -w -i -p\n\n";
for my $fn (@ARGV) {
    if (! exists $macros{$fn}) {
	print "# No macro known for $fn!\n" if (!$skipped{$fn});
	next;
    }
    if ($macros{$fn} !~ /_H_?$/) {
	print "# Weird macro for $fn...\n";
    }
    my $goodmacro = uc $fn;
    $goodmacro =~ s#.*/##;
    $goodmacro =~ s#[\/\-\.]#_#g;
    print "s/(?<![A-Za-z0-9_])$macros{$fn}(?![A-Za-z0-9_])/TOR_${goodmacro}/g;\n"
}
==============================

It produced the following output, which I then re-ran on those same files:
