Change p7zip to p7zip-17.03 (new upstream location)

[Douglas R. Reno]

As mentioned by Ryan Marsaw on 1/30/2021 on blfs-dev, p7zip has been forked and is now actively maintained. The fixes that we have in the book have been put into this version as well.

Here's a copy of the email:

I'd like an opinion or two before I proceed with this though.

As far as I can see, debian is still using sourceforge. They have patches (several debain specific) at ​https://salsa.debian.org/debian/p7zip/-/tree/master/debian/patches

Replying to pierre.labastie:

Debian is always dependant on what individual maintainers choose to do, or not do - I recall that for years they were stuck on an old version of mawk because someone wasn't happy (ISTR that the debian dev didn't trust the upstream dev, and the upstream was the xterm developer, but I may be wrong). Anyway,do they even know there is a fork ?

Other distros with the fork mentioned at ​https://repology.org/project/p7zip-jinfeihan57/versions appear to be Arch (I guess that might be where Ryan spotted this), KaOS (?), Mageia, Manjaro, Msys2 (not sure I'd count that as a linux distro) and Termux (?). Not sure how "official" the non-Arch usage is, but the fork does seem to be becoming available.

But I don't have any skin in this game, p7zip is not something I use.

The last release was in 2016 from SourceForge, and there are 132 tickets open.

I think this Github Issue might give out some more useful information: ​https://github.com/jinfeihan57/p7zip/issues/114

I'll get Jasper and Glib in at my next commit.

The new URL for p7zip will be: ​https://github.com/jinfeihan57/p7zip/archive/v17.03/p7zip-17.03.tar.gz
