* In Render tolerate not being passed a context
It is possible for RenderString to be passed to an external renderer if markdown
is set to be rendered by an external renderer. No context is currently sent to these
meaning that this will error out.

* Add Context to Repo calls for RenderString
All calls from routers can easily add the context - so add it.

The fuzzer found an issue with the issue pattern processor where there is a spurious
path.Clean which does not need to be there. This PR also sets the default AppURL for
the fuzzer too.

If a pre-post-processed file contains relative img tags these need to be updated
and joined correctly with the prefix. Finally, the node attributes need to be updated.

Unfortunately go doesn't always ensure that execd processes are completely
waited for. On linux this means that zombie processes can occur.
This PR ensures that these are waited for by using signal notifier in serv and
passing a context elsewhere.

* More efficiently parse shas for shaPostProcessor
The shaPostProcessor currently repeatedly calls git rev-parse --verify on both backends
which is fine if there is only one thing that matches a sha - however if there are
multiple things then this becomes wildly inefficient.
This PR provides functions for both backends which are much faster to use.

There is an inefficiency in the design of our processors which means that Emoji
and other processors run in order n^2 time.
This PR forces the processors to process the entirety of text node before passing
back up. The fundamental inefficiency remains but it should be significantly
ameliorated.

Bluemonday sanitizer regexp rules are not additive, so the addition of the icons,
emojis and chroma syntax policy has led to this being stripped.

Fix#12925

PostProcess is supposed to be parsing and handling HTML
fragments, but on fuzzing it appears that there is a weird
issue with NUL elements that could cause a memory address
error in downstream libraries.
The simplest solution is to strip out the weird NULs - they
should not be there in any case and would be stripped out
anyway.
