Clean up some of the fallout from the Solaris patch - mostly configure
script breakage.  In particular, disable the sendfile() check, as Solaris
doesn't have a working sendfile() any more than Linux does.  Actually, the
Solaris sendfile code was never compiled or used, because the #ifdefs in
cache_pool.c were all wrong.

Strictly speaking, we should test $target, not $host - although in practice,
varnish is not cross-buildable anyway due to the SO_RCVTIMEO / SO_SNDTIMEO
tests.

I need a printout for a code-walkthrough and this commit wraps lines,
removes trailing space, space before TAB and other iregularities.

Some generated files have been compacted a bit.

A few changes to comments along the way.

Original commit message:

storage_file prints the maximum storage size, make malloc do the same,
for consistency.

Make sure that
        set obj.ttl = 0s
means that the object is not hit again by actually using "-1" instead.

This works around the rounding error which otherwise causes the object
to be inside TTL for up to one second - epsilon.

Add a test of the random director that uses actual randomness.

This will be skipped on platforms where srandom(1) does not result
in the same deterministic sequence of random numbers as on FreeBSD
and Linux.



git-svn-id: http://www.varnish-cache.org/svn/branches/2.0@3535 d4fa192b-c00b-0410-8231-f00ffab90ce4

Add a toplevel word which examines the sequence returned by
srandom(1) and stops the test if we do not get the same sequence
as we expect.

The Open Group does not define which deterministic sequence srandom(1)
should result in, on that it be deterministic, but I have high hopes
in the general sanity and expect that UNIX people across the board
have realized that for portability the same sequence should be
returned on all platforms.

At the very least FreeBSD and Linux/GLIBC, as seen on projects.linpro.no,
agree.

Add a debug CLI command to seed random(3).

This is a lot less useful than it could have been, as the Open Group
only mandates that:

        Like rand(), random() shall produce by default a sequence
        of numbers that can be duplicated by calling srandom() with
        1 as the seed.

But crucially leaves out *which* sequence of numbers.
