gcc 4.1.2 (and previous version I assume) doesn't support it.

The standard storage in our other Linux packages is 256 MB malloc.

Change the default on Redhat systems to match this.

Since we removed the bundled jemalloc, our packages have been
using system malloc on RHEL Linux.

As Ingar mentions in #1445, this is a workaround for the
dependency issue.

Originally attempt at a shorter fix in 6dc740f0 didn't work out.

find-provides did not pick up on libvarnishapi.so.1 for varnish-libs
automatically, and find-requires for the main package did. This meant
that package pair was uninstallable.

I don't quite know why this is happening, so I'm working around it
with a hardcoded Provides for now. This is on the critical path for
4.0 release.

This was reduced to 20 seconds in 6d0c94c3.

The git commit message does not mention default_ttl, and since this was a
fairly big commit, I don't believe the change was intentional.

Postpone invoking list_fields() until after VSM_Open().

You need to know what you are doing.

Critbit is teh shit.

it is buggy, work around it.  If the backend sends chunked encoding
we don't catch it and fail the transfer.
