Previously we always used SO_LINGER to make sure that all queued data
got transmitted, no matter under which circumstances we closed the
client connection.

Change this so that SO_LINGER is only activated for orderly connection
closure (ie: "Connection: close" from client or error handling), in
all other cases (usually the client connecting on us, abandon any data
queued for transmission.

This _may_ reduce the tendency of worker threads to get hung up on
network failures a little bit.

and this prevented users from implementing "purge on POST" semantics
by looking up the POST requests and ditching the object found.

Now we only overwrite the request with "GET" if it is a HEAD, (the
internal "wantbody" flag tells hos how the response should be composed.)

The testcase shold probably be elevated to VCL example, with suitable
footnotes about URL sanitizing etc.

fix for #498 -- if a return header overran the obj_workspace (but was small enough to fit in sess_workspace) the header is dropped and an empty slot is put in there -- rest of the code now detects this empty slot. It should probably ask VLC what to do if a header is dropped

Fix for bug 476 -- ESI was using null chars to deal with the strings, this made it impossible to pass binary CDATA through the ESI parser. This switches it to compare against the end pointer of the string. Test case attached.
