Bug fix: TLS/SSL Options does not apply to the dynamically generated certificates
The TLS/SSL options configured with http_port configuration parameter does not
used to generate SSL_CTX context objects used to establish SSL connections.
This is means that certificate based authentication, or SSL version selection
and other SSL/TLS http_port options does not work for ssl-bumped connection.
This patch fixes this problem.

Bug 3626: Forwarding loops on intercepted traffic
Changes to interception handling in 3.2 series (namely the preference
for using ORIGINAL_DST) have increased the chances that misconfigured
network systems involving Squid will hit forwarding loops.
Two instances are currently known:
* passing forward-proxy traffic to a interception port.
* NAT performed on a separate box.
This enacts an old TODO by removing the loop detection bypass for
intercepted traffic and accelerated traffic. Now we always check for
loops regardless of how the request was received.
NOTE: accel mode was only included due to the TODO.
If problems are found there it can be re-instated.

Make CpuAffinitySet::applied() method non-const.
According to CPU_SET(3) and, apparently, on some systems (e.g.,
OpenSuSE 10.3) CPU_COUNT macro expects a non-const argument. The
patch fixes build error on these systems.
Retrieve client connection information for ACL checks from the related HttpRequest object
This patch enable SSL client certificate ACL checks (user_cert and ca_cert)
in all cases the client connection information can retrieved from the related
HttpRequest object, eg when making peering decisions (peer_cache_access ACL).
Discussed under the "Supply client connection and IDENT information to
peer_cache_access ACL check" thread on squid-dev.

Regression: login=PASS send no credentials when none available.
login=PASS should act like PASSTHRU, sending no credentials header, when
no client supplied OR external ACL credentials are available.
3.2 has been found wrongly adding the username "PASS" in this case.
Bug 3613: relax standard-compliance strctness on clang to enable build
When clang is invoked with the -std=c++0x option, it won't make available some system functions
defined in c99. For some reason configure fails to detect this, and so the built-in implementation is
not invoked. This change prevents enabling the -std=c++0x option for clang.
Prep work for automatic sorting of include directives.
Automatic sorting of include files reveals some indirect inclusions, which would break the build.
scripts/sort-includes.pl is the tool to do the automatic header include order sorting.
The other changes in this set fix the issues which that be introduced by running the sorting.

Remove --enable-ntlm-fail-open
This feature has been half missing for quite some time (10 years).
The SMB helper sends the LD code back to Squid when the directive is
compiled in, but there is no Squid code handling such responses, back as far
as squid-2.
clang++ doesn't support c++ variable arrays for non-pod types.

Support -DFAILURE_MODE_TIME=n compiler flag
This value determins at compile-time how long Squid spends in HIT-only
mode after the failure ratio goes over 1.0. see checkFailureRatio() in
src/client_side_request.cc for details on the ratio.
This flag is supported to remove the need for patching when alteration
is required.
This re-enables Squid peer selection algorithms for intercepted
traffic which has failed Host header verification.
When host verification fails Squid will use, in order of preference:
* an already PINNED server connection
* the client ORIGINAL_DST details
* cache_peer as chosen by selection algorithms
NOTE: whenever DIRECT is selected by routing algorithms the
ORIGINAL_DST is used instead.
Peer selection results are updated to display PINNED and
ORIGINAL_DST alongside DIRECT and cache_peer.
SECURITY NOTE:
At this point Squid will pass the request to cache_peer using the
non-trusted Host header in their URLs. Meaning that the peers
may still be poisoned by CVE-2009-0801 attacks. Only the initial
intercepting proxy is protected.
Full protection against CVE-2009-0801 can be enjoyed by building
Squid with the -DSTRICT_HOST_VERIFY compile-time flag. This will
make the peers unreachable for intercepted traffic where the
Host verification has failed.

For simplicity of maintenance I'm adding @Squid-X.Y labels at the

Allow a ufs cache_dir entry to coexist with a shared memory cache entry
instead of being released when it becomes idle.
The original boolean version of the StoreController::dereference() code
(r11730) was written to make sure that idle unlocked local store_table entries
are released if nobody needs them (to avoid creating inconsistencies with
shared caches that could be modified in a different process).
Then, in r11786, we realized that the original code was destroying non-shared
memory cache entries if there were no cache_dirs to vote for keeping them in
store_table. I fixed that by changing the StoreController::dereference() logic
from "remove if nobody needs it" to "remove if somebody objects to keeping
it". That solved the problem at hand, but prohibited an entry to exist in
a non-shared cache_dir and in a shared memory cache at the same time.
We now go back to the original "remove if nobody needs it" design but also
give non-shared memory cache a vote so that it can protect idle non-shared
memory cached entries from being released if there are no cache_dirs to vote
for them.
