tests: use $DAEMON_PIDS and killdaemons in largefiles test

$DAEMON_PIDS is used by tests to make sure there will be no leftover
processes, the cycling through ports is needed because they are not
available for a new bind that quickly on some systems.

There are not enough $HGPORT variables available for each hg serve,
so use the killdaemons script before reusing ports.

#!/usr/bin/env python

import os, time, errno, signal

# Kill off any leftover daemon processes
try:
    fp = open(os.environ['DAEMON_PIDS'])
    for line in fp:
        try:
            pid = int(line)
        except ValueError:
            continue
        try:
            os.kill(pid, 0)
            os.kill(pid, signal.SIGTERM)
            for i in range(10):
                time.sleep(0.05)
                os.kill(pid, 0)
            os.kill(pid, signal.SIGKILL)
        except OSError, err:
            if err.errno != errno.ESRCH:
                raise
    fp.close()
except IOError:
    pass
