Set default formatting flags for the debugging stream to "fixed" with a

This change affects pretty much all debugging output, although most messages
will not change in appearance. Compilation errors are possible. The patch was
posted to squid-dev in August 2007. I do not recall any objections but
apparently I forgot to commit it.

Bug 2096: allow pending cache hits when delay pools not compiled in
For some time now, Squid has marked pending cache hits (a cache hit
when e->store_status != STORE_OK) as LOG_TCP_MISS. This was done
so that pending hits do not bypass delay pools. It had the negative
side effect of generating confusing access.log entries because cache
hits get logged as miss.
With this patch, the behavior is reverted when delay pools are not
compiled in. Pending hits will be logged as some kind of TCP_HIT.
Users of delay pools will just have to live with this logging quirk,
although the "forwarded to" field of access.log can always be used
to see if the request was forwarded (a miss) or not (a hit).

More fixes for recent MD5 mixups
- Changing 'xMD5' function name to 'SquidMD5'
- Changing 'MD5_CTX' typedef to 'SquidMD5_CTX'
- Changing 'MD5_DIGEST_CHARS' define to 'SQUID_MD5_DIGEST_LENGTH'
- Changing 'MD5_DIGEST_LENGTH' define to 'SQUID_MD5_DIGEST_LENGTH'

Fix-fix for MD5.
Pre-compiler only tested on Linux and FreeBSD.
This update amends the previous to allow OS which provide a partial MD5
implementation but do not supply correct buffer size (MD5_DIGEST_* macro)
to build using the squid bundled code.
To evade symbol-clashes the squid code is also updated to use xMD5Init,
xMD5Update, xMD5Final and the code sorts out which version is to be used
at compile time from configure options and available sources.
For MacOS X and other broken OS the sys/types.h must also be included on
behalf of the sys/*.h which need it.

Enable squid to lookup /etc/services for named peer ports.
Here is patch so you can use port names from /etc/services in
squid.conf for cache_peers like so:
cache_peer upstream.example.net parent http-cache icpv2
assumng you have something like this in /etc/services
http-cache 8080/tcp
icpv2 3130/udp

across a cluster of reverse proxies and we control originserver
addresses via a hosts file and originserver ports via /etc/services

Looks like 'dstdomain' and 'dstdomain_regex' ACLs were broken.
The dst_addr member of ACLChecklist class was never set so
certain reverse lookups for 'dstdomain' and 'dstdomain_regex'
ACLs probably were not working. This patch sets dst_addr
before (potentially) doing the non-blocking lookup.
When Squid is not doing the ranges it may still forward a Range request to the
origin server and receive a range response. The old code was comparing
endOffset of memObject with the last expected offset according to the Range
header value. That comparison did not account for the header size in
endOffset.
I do not know if the header size should not have been there or
should have been accounted for in the comparison. Adding headers size made
the 206 problem more difficult to reproduce (but it was still there).
Instead of trying to figure out when the header should or should not be
counted, I used http->out.offset and reply->content_range->spec.length. That
seems to work. This change, however, is in my Puzzle Area of Squid; I have low
confidence the fix is correct and cannot be improved.

Bug 2104 fix: handle REQMOD HTTP responses without body
When in request satisfaction mode and no body is expected, mark the store
entry as complete. Otherwise the ClientStreams(?) triggered by the
clientGetMoreData call will get stuck waiting for more data from the store.
There is probably a better way to do this (e.g., completely bypassing store).
The tunnelConnectTimeout function used the tunnelState object (and propably
the tunnelState->request object) after they were freed by the comm_close call.
The fix moves the comm_close call to the end of tunnelConnectTimeout.

Likely fix for helper-related SEGV shortly after reconfigure
I'm seeing occasional SEGVs in helperHandleRead() shortly after
a reconfigure. I suspect that the helper structure was kept
around during the reconfigure because of a pending request. If
it gets closed in helperHandleRead() after reading, then we must
return from the function rather than continue in the while loop.
