Bug 1843: multicast-siblings cache_peer option for optimising multicast ICP relations
'multicast-siblings' : this option is meant to be used only for cache peers of
type "multicast". It instructs Squid that ALL members of this multicast group
have "sibling" relationship with it, not "parent". This is an optimization
that avoids useless multicast queries to a multicast group when the requested
object would be fetched only from a "parent" cache, anyway. It's useful, e.g.,
when configuring a pool of redundant Squid proxies, being members of the same
multicast group.

WCCPv1 not connecting to router correctly
I am coming across a problem with WCCPv1...
squid-2.5 connects to UDP port 2048, I get replies, and everything else then works.
squid-3.1 looks like it is trying to connect to UDP port 0 on the cisco.
[and fails to work]
I have looked at the src/wccp.c for squid-2.5, and it is clear that the port is
being set to 2048 for the connection to the router.
I have also looked at the source for 2.6, 2.7 and 3.0 (src/wccp.cc for this
version).
In all those, it appears to be setting the port on the outgoing connection.

Add the http::>ha format code and make http::>h log original request headers
This patch:
- Modify the existin "http::>h format code to log HTTP request headers
before any adaptation and redirection
- Add the new format code "http::>ha" which allow the user to log HTTP
request header or header fields after adaptation and redirection.

Bug 2730: Regressions in follow_x_forwarded_for since Squid-2
Two Major Regressions:
* Omitted testing for trust of the directly connecting client.
this is critical is trusting the header content itself.
The absence permitted remote clients to forge X-Forwarded-For
and gain access to resources through Squid.
(mitigated by the following)
* Bad logic in implementing the trust model resulted in any XFF
headers containing untrusted IPs to be dropped in their entirety.
This resulted in clients transiting more than one proxy heirarchy to
be incorrectly logged and reported in the second.
Some polish alterations to the existing logics:
* Testing the direct client address for trust means the testing must be
fully async 'slow'. Thus avoiding the memory leaks found on occasion.
* acl_uses_indirect_client is not strictly needed to test multiple levels
of X-Forwarded-For properly. The entire list of IPs are now always
tested until an untrusted is found or an ACL failure occurs.
- Remove 'odd' netmask support from ACL.
- Fully deprecate netmask support for ACL.
Earlier fix caused inconsistent handling between IPv4 and IPv6 builds of
Squid. Which has turned out to be a bad idea.
This fixes that by 'breaking' both build alternatives.

Add client_ip_max_connections
Given some incentive after deep consideration of the slowloris claims.
While I still do not believe Squid is vulnerable per-se and some people
have tested and found no such failures as claimed for the DoS attack.
We found we could provide better administrative controls. This is one such
that has been asked about many times and still did not exist. It operates
essentially the same as maxconn ACL, but does not require HTTP headers and
other request data to fully exist like ACLs do.
It is tested immediately after accept() and is request type agnostic, right
down to DNS TCP requests. So care is warranted in hierarchy situations or where
clients may be behind NAT.
Utilizes the client DB to monitor accepted TCP links. Operates prior to
everything so as to eliminate resource usage on the blocking case and
close the windows of opportunity for dribble-attacks etc.
Default (-1) is to keep the status-quo of no limits.

Regression Fix: Make Squid abort on parse failures.
The addition of multi-file parsing and catching of thrown errors between
them caused any errors in sub-files to be non-fatal and allow Squid to
run as if everything was normal, even if parts of the config were not
being loaded.
Squid will now propigate the error exception out and exit with a count of
the errors found.

Bug 2811: pt 1: Correct Peer table OID numbering
The IPv6 alterations to the cache_peer table display should not have
altered existing OID numbers. This fixes that by bumping the new table
format to a new OID number .1.3.6.1.4.1.3495.1.5.1.3 for version 3 of the
table.
NP: version 1 of the table was in 2.0->2.5, and 3.0
version 2 of the table was in 2.6+

Account for mem_node overhead inside cache_mem
This makes squid include the overhead memory space when determining the
number of data pages available in cache_mem memory space. Forming a much
better limit on memory cache usage.
This does NOT solve any issues created by sizeof(mem_node) being unaligned
with the system malloc implementation page size. That still needs to be
resolved.
The patch allows Squid v3.1 to build on RHEL 5.4 which has autoconf v2.59.
Without the patch, USE_DISKIO_AIO is zero but the corresponding AIO files
are compiled, leading to errors. I do not know if other platforms are
affected.

Bug 2830: clarify where NULL byte is in headers.
Debug printing used to naturally stop string output at the null byte.
This should show the first segment of headers up to the NULL and the
segment of headers after it. So that its clear to admin that there are
more headers _after_ the portion that used to be logged.

Polish ACL src/dst magic monikers and push upgrading to 'all'.
* Adds 'ipv4' magic moniker. Slightly safer and friendlier than !ipv6
* Updates the IP range parse to detect several old broken cases of 'all'.
Warn loudly and replace with 'all' during parse.
This is needed for all the people who use the 'all' pattern for special
purposes under another name; auth hiding, deny_info redirects, etc.

Split in multiple expressions specified by -e arguments. Seems to work better.
The large blob had a bit of extra space characters in it from the line folding
which seems to be related to the failure. (each command began with a space)
