Remove unnecessary files from spkg/standard

In SAGE_ROOT/spkg/standard, with 4.5.alpha0, I see:

The files libdist_filelist, notes.txt, and numeric-24.2.txt seem like leftover notes that. Can I delete them? 

The files libdist_filelist, notes.txt, and numeric-24.2.txt ​have been removed from Sage 4.5.2.alpha1:

The second unreviewed change is the deletion of several extra files in spkg/standard, as I mentioned in https://groups.google.com/group/sage-release/t/b6fd67d4d4543129. In the unlikely case that those files were important or necessary, we can just copy them from the alpha0 tarball. 

This ticket is for reviewing the change.

Possibly related:

$ cd SAGE_LOCAL/bin
$ grep libdist *
sage-libdist:libdist_filelist = open('%s/spkg/standard/libdist_filelist'%r
sage-libdist:    if len(ext) > 1 and not name_without_version in libdist_filelist:
sage-libdist:This is the readme for sage-libdist, which is the
sage-libdist:libdist = 'sage-libdist%s'%r[i:]
sage-libdist:if os.path.exists(libdist):
sage-libdist:    os.system('rm -rf %s'%libdist)
sage-libdist:os.system('mv %s %s'%(r,libdist))
sage-libdist:os.system('tar -cvf %s.tar %s'%(libdist,libdist))
sage-libdist:os.system('rm -rf %s'%libdist)
sage-sage:   "$SAGE_ROOT"/local/bin/sage-libdist sage-$2.tar
sage-sdist:cp -p $PKGDIR/$STD/libdist_filelist $TMP/$PKGDIR/$STD/

But I can't investigate further right now.

As part of the file "sage-sage":

   echo "sage -ldist currently disabled"
   echo "To work on it, remove the exit after this message in SAGE_ROOT/local/bin/sage-sage"

So sage-libdist is not currently active. I think that we should keep the file libdist_filelist just in case. In my opinion, the other two files can be removed, but I don't know their history. You might ping William about this.

Also, as mpatel points out: the script sage-sdist tries to copy libdist_filelist, so that may break with this file missing.

Okay, it looks like we should put libdist_filelist back in (and then, in my opinion, find out why it's there and if possible, open a ticket for removing it and the parts of the scripts that reference it).

The numeric-24.2.txt is a short description of a Python module that we don't ship. Even if we did include it, I can see no reason why such a file should be kept in spkg/standard.

notes.txt refers to the sage_c_lib package, which no longer exists, and to a very outdated version of linbox. The libtool information in that file should be kept in the linbox spkg and/or put on the wiki.

I think we can resolve this ticket by just putting libdist_filelist back.

[jhpalmieri]

Sounds good to me. We can always recover the other files from an old tarball if we ever need them.

I'm including 4.5.2.alpha0's spkg/standard/libdist_filelist in 4.5.2.rc0.
