this is much cleaner and does not demand a brand new python interpreter.

Be a total CPP-show-off-douche and make it very easy to add further
variables in the future, provided you can find the magic table.

Presently define three variables:


	REAL storage.$stevedore.free_space
	REAL storage.$stevedore.used_space
	BOOL storage.$stevedore.happy

Still debating if I should add a "SPACE" type to VCL, so that you
can write:
	if (storage.foobar.free_space < 1 GB) {...}

until I decide, it is a REAL, which is less than useful, because
we have no relational operators besides identity for REAL.

Presently, you can only test for the existence of a given stevedore,
but it gets a lot of support code in place.

This is a generalization of the trick we have used for things like
req.http.foobar, which can now also be used with other parts of
the namespace.

The plan is to use it for storage.disk1.free and similar.

We will no longer allow an object to be split across multiple
stevedores, because the necessary logic to allow control of which
stevedores allow this (malloc, file) vs. those that cannot tolerate
this (persistent) is just not worth the effort.

It is very dubious if there are any non-disadvantages to splitting
objects across stevedores in the first place.

in critbit to avoid a malloc in the locked path.

Move the waitinglist to its own structure in preparation for Big
Things Afoot which will give it more work to do.  This saves a
pointer in objhead on average, always a good thing.

Have the worker thread preallocate a waitinglist structure.

The last argument to any CLI command can use this feature.

Typical example:

	vcl.inline vcl_new << 42
	backend foo {...}
	sub vcl_recv {...}
	42

The advantage is that no escaping is needed, as long as the magic
marker, in this case "42" does not match any line anywhere in the 
lines that make up the argument.

Arguments encoded this way are not subject to the "cli_buffer"
parameters size limitation.

reflect the sum of obj.ttl and obj.grace.

Obj.grace if not set, default to $default_grace, which might have
a different value when we open the silo in a new run.

Solve this, by saving the ttl as the negative sum of (obj.ttl + obj.grace)
if obj.grace is set, or the positive obj.ttl if it is not, and by
adding $default_grace to obj.ttl in the latter case.

of work to do, this timestamp could get behind times, and send the
thread to sleep, despite being behind on work.

Fix this, by updating the timestamp whenever we run out of work.

Add a parameter ("expiry_sleep") to control how long time the thread
will sleep so this can be tuned down on high-load servers.

Contrary to the previous comment in cache_expire.c, this process is
guaranteed to work because the shuffle will always terminate either
in the root position or in the bottom row.

Use this function when we adjust ttl on an object.
