Varnish panic API

[Martin Blix Grydeland]

Hi phk,

Now that we expose the panic functions also to vmods, I believe we need to
define a somewhat cleaner way for different parts to produce the panic
output. It's the indentation and how that's hard coded into each panic
generator that's the major issue in my opinion, e.g. how the panic handler
in the backend vmod would have to now to insert 4 character whitespace on
each line in order to match it with where it's output would probably go in
the panic string.

The attached patch series changes this. It's a lot of patches, as it
changes all of the panic code slightly. First one shows the utility
functions I created for this purpose, and the rest are patches for
different panic string generators.

Martin
