enable abs_integrate package from maxima

[kcrisman]

This is the followup to #8624, as suggested in #10434.

We want to do more integrals! There are lots at the patch at #8624 which it would be great to add.

Depends on #12094

See this sage-devel discussion for someone working on this!

Also, see #11966 for a newer spkg to base upon.

Here's my shot at this. There's one regression (a Maxima bug) that's fixed by Maxima 5.24.0, thus the dependency.

Ok, this looks good, and is the proper way to deal with this. All tests pass.

Should we add Jason as an author due to his work at #8624? Up to him, probably.

Scratch that - Michael, can you update and give a proper commit message etc.? Also, the documentation is incorrectly formatted with double colons etc. - including the zXXX comment, which should have the double colon for EXAMPLES made single and then have a double colon after "subject to change".
