[PATCH v2 00/15] Render READMEs inline in tree view

[Andy Green]

The following series adds config to allow rendering of
selected READMEs inline after the tree view, where
present in the directory being viewed.

Particularly you can use completely relative markdown to
inline pictures served from the current repo rev context,
eg,

![overview](./doc-assets/overview.png)

will "just work" showing the png from the current view
rev context; this format also works in github.

It builds on John Keeping's RENDER mode series from 2016.

Typical config to enable it, if you have a README.md
looks like

inline-readme=README.md
render.md=/usr/libexec/cgit/filters/html-converters/md2html

You can see examples of it in operation at

https://libwebsockets.org/git/libwebsockets/tree
https://libwebsockets.org/git/libwebsockets/tree/?h=v3.0-stable
https://warmcat.com/git/cgit/tree/

The expected basis these apply on top of is

 - jk/for-jason
 - ch/git-2-18-0-rc2

You can find these patches on top of the expected basis here

The series is adapted for many comments on the list, including
one-shot inline rather than a list, repo config override,
dropping one patch of gcc8.1 fixes, integrating John's md2html
changes etc.

There's a new patch about tidying the manpage... the couple
of alphabetically-ordered lists in there had things that
were out of order.
