Forking ebook-tools

[Albert Astals Cid]

I talked about this in Akademy to a few of you already but mentioning it here 
in case someone has comments/objections.

We use ebook-tools in both kfilemetadata and okular.

Looking at archlinux dependencies we are the only people using ebook-tools.

ebook-tools is unmaintained since more than a decade.

ebook-tools is very crashing as found by oss-fuzz.

For all the reasons above I have forked ebook-tools at 
https://invent.kde.org/aacid/ebook-tools

I will be asking for it to move into a non-user-namespace (graphics? 
libraries?) on Wednesday 11 and make a new release (keeping the same name) 
soon after that.

Cheers,
  Albert
