add two sbufs for "init" and "fini" actions.

VCL ACLs:  Change syntax and implementation as follows.

ACL Syntax now works the following way:

	acl $name {
		! ( "myhost.com" ) ;
		"10.0.0.1" /8 ;
	}

The '!' means not.  If the address matches the rest of the rule
the address does NOT match the acl and the search terminates here.

Enclosing the string in paranthesis means that the rule will be ignored
if the string cannot be converted to an address (with getaddrinfo).

When a string can not be looked up, and is not enclosed in a
paranthesis, a positive rule (ie: without !) will not match and a
negative rule (with !) will match.

A mask can always be supplied, no matter the style of the string
given, so it is possible to do things like:

	{ "fw.ourcompany.dom" / 24 }

Which means "any host on the same /24 subnet as fw.ourcompany.dom".


Unfortunately getaddrinfo() does not return a TTL for the results,
in the future we may want to use some kind of timeout to refresh
the lookups.

Remove sbuf from workerthread, it is only used in the Error handling
now and it will probably not even survive that in the long run.

NB: Only pass mode (lightly) tested right now.

Give up on the three element array per header and use a two element struct
instead, it reduces obfuscation and removes risk of pointer fandango.

Introduce #defined filtercontrol in http_headers.h, use them in a new
field.  Only Pass is there for now.

Use the http-workspace for building headers instead of sbuf.

Move uiovec handling to cache_pool.c where it more naturally belongs
and so we can use it on both backends and sessions.

Add http header munging functiosn for copying, printf'ing, filtering and
writing headers.

Remove unused variable

Record a triplet of {start, data, end} for all HTTP data items.

This represents a regrettable uglification of the sourcecode, but
most of it compiles out to constants and the runtime benefits will
be worth it.

Generate H_FOO magic strings for all the headers we know about.
These strings have a length as first char and always ends in ':'.

Also genereate H_FOO format strings in VCL compiler.

Mandate (with assert) that header references happen using H_FOO strings.

Make number of allowed HTTP headers a compile time constant (32)
but make the workspace a run-time variable (4096).

Introduce new SHM tag for dumping aborted HTTP protocol requests.
