Update PARI to version 2.5.0

[jdemeyer]

We need to add bugfixes for

1. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1147 (related to Implement Hilbert symbols over number fields #9334)
2. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1153 (Occasional doctest failure in libs/fplll/fplll.pyx #10195)
3. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1154 (PARI qfminim bug on 32-bit systems (Sage 4.7 and 4.6.2) #11604)
4. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1184 (related to PARI real precision is broken in many ways #9937)
5. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1185 (PARI bug discovered by a Sage doctest)
6. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1186 (PARI performance regression discovered by a Sage doctest)
7. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1187 (PARI bug discovered by a Sage doctest)
8. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1188 (PARI bug discovered by a Sage doctest)
9. http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1192 (Fractional ideals intersection gives wrong answers in some cases. #10767)

We will do this by updating to PARI version 2.5.0, which is equal to svn revision 13228.

I am currently testing this. To avoid duplication of effort, I'll fix things I find in the elliptic_curves directory only.

After (1) Building a fresh 4.7.alpha5 from scratch, (2) installing the spkg lined here with "sage -f", (3) applying the patch here to the sage library and (4) running "sage -b", I find that the Sage build will not start up properly:

ImportError                               Traceback (most recent call last)

so I cannot test anything.

Did I do something wrong?

I see! I'll have some time to spend on this tomorrow (Monday) so I'll have another go.

Sounds good, I will look at everything else.

Fix 32-bit doctest for sage-4.8.alpha1

[jdemeyer]

Attachment: 11130-4.8.alpha1.patch.gz

Added an additional patch attachment: 11130-4.8.alpha1.patch. Not sure how this extra doctest failure happened, but in any case this trivial patch fixes it. It simply sets the 32-bit result equal to the 64-bit result. I hope nobody minds if I leave the positive_review (not to drag this ticket longer than necessary).

Fine with me. The 32/64 bit differences in pari are such a nuisance, as I have told Karim more than once...
