This is equivalent to synthetic but using the more general set keyword.

Before this commit it was only sent on pass'd requests, making
impossible to cache e.g. POST requests.

To keep the previous behaviour unset bereq.body if the method is GET,
which is normally true for misses.

Fixes #1927.

Only available in vcl_backend_fetch{}. If it is unset varnish will not
pass the request body to the backend.

This is in preparation for addressing #1927.

When handling a fetch error we may not even have had memory to store
the status code.

Fixes #1990

Relates to #1990

soon need them.

Fixes #1989.

actually possible to locate the compiled VCL shared library based

- tables get included multiple times
- we use do ... while(1) all over the place
- dont always include config.h for flint, source files need to include it
  so we want to see warnings if we missed to include it
- tell flexelint where config.h is ok not to be used (sources with
  no actual code unless a feature is HAVE_ defined)

Test by scn@. OK by @phk.

Fixes #1963.

The counter g_cooling variable is now decremented when memory from the
cooling list is freed, making the counter vsm_cooling update
accordingly.

Fixes: #1984

This new parameter specifies how long freed VSM memory is on the
cooling list before it is actually freed.
