      Remove the vcl_timeout{} VCL callback. · 236e1950

      We had big plans for this originally, but none of them have materialized
because there are better ways to do those things.

For instance: why invent a lot of code to do prefetch, when wget(1) can
do the job already ?

Getting rid of vcl_timeout{} (and vcl_discard{}, see yesterdays commit)
simplifies the expiry codes locking and statekeeping significantly.

      Remove the vcl_discard{} facility, it does not seem to bring benefits · b1fe4dfd

      which outweigh the trouble it causes.

The original idea was to allow intelligent purging for space reason
in a size-constrained storage.

In practice, storage is seldomly constrained.

In the cases where it is, I have yet to see any documented benefit
from using vcl_discard{}, likely because of the fragmentation such
use would cause.

The implementation of the vcl_discard callback had severe costs in
code complexity (not fully unrolled by this commit) and locking
activity.

The straw that breaks the camels back, is that faithfull implementation
of vcl_discard{} in -spersistence would force us to relocate objects,
at a cost likely higher than picking them up from the backend.
