[MERGE] Honor octal and hex prefixes in squid.conf integers

Hello,

    A umask port from Squid2 discovered that Squid3 parses squid.conf
file integers as decimal numbers while Squid2 honors 0 and 0x prefixes
(indicating octal and hex numbers). The later functionality is needed
for things like unmask that are traditionally specified using octal
format.

The change to honor other integer bases was introduced in Squid2 before
2005/05/17. I failed to track the commit that did it, unfortunately. The
cache_cf.c file was changed in Squid2 HEAD as the result of this:

> revision 1.422
> date: 2005/05/17 16:56:37; author: hno; state: Exp; lines: +285 -209
> Reset Squid-2 HEAD to the current state of Squid-2.5 to reduce confustion
>
> the old Squid-2 HEAD is available as the branch OLD_SQUID_2_6 if needed.

My patch changes Squid3 behavior to match that of Squid2.

The alternative is to add a new "base_integer" type to squid.conf. That
type would honor prefixes while the current "int" type will not.
However, if Squid2 did not significant problem with flexible integer
parsing, Squid3 should be OK as well. Also, such a subtle difference
between the two configurations would make upgrading more difficult for
those rare cases where an admin used a non-decimal integer in squid.conf
for things other than umask (on purpose or by accident).

I doubt bzr managed to generate a proper bundle, even though I did
follow instructions and did _not_ commit before running the two commands
below. I have no idea why bzr send did not work and --verbose does not
produce more info.

  bzr diff -r submit: | less
  bzr send --mail-to=squid-dev@squid-cache.org

To compensate, I am quoting the one-line patch below.

Thank you,

Alex.
