This could happen on a 200 synth object if the client request had a
Range header. The range code path would fail because it requires an
obj which the synth path doesn't have.

Fixes: #1660

Keep the fetch thread busyobj pointer-ref separate from the client thread pointer-ref, and deref it on thread scheduling failure.

The code tried to deref the same pointer twice, which failed because
the VBO_DerefBusyobj() will clear the pointer when called. Separating
allows calling VBO_DerefBusyobj() for each of them.

Don't attempt to run the fetch in the request thread if there are no threads available in the pool, fail the fetch and count it.

While here display the right VCL name if -v is used and the VCL is
not found.

This manpage is auto-generated. Remove author, date and whatnot, it
doesn't make sense here.

e.g. <undef> >= 0.1 should fail for being an invalid comparison

Fixes: #1378

The streaming fetch of an object can fail between lookup time and when
we actually use it. Relax this assertion.
