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.

logical.

Rename http_Init() to http_Setup() to avoid clash with HTTP_Init().

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.
