NOTE: According to http://pari.math.u-bordeaux.fr/packages.html, there are now two seadata tarballs; we'll have to make one standard, and one optional.

The new ellap (which replaces the sea.gp script in sage) is seriously buggy, evidently. Sometimes it works, but the first example I tried fails miserably.

? ellap(ellinit([1,2,7,4,3]),nextprime(10^20))
%1 = -4070602678
? ellap(ellinit([1,2,3,4,5]),nextprime(10^20))
  ***   at top-level: ellap(ellinit([1,2,3
  ***                 ^--------------------
  *** ellap: bug in PARI/GP (Segmentation Fault), please report
  ***   Break loop: type 'break' to go back to GP
break> 

? ellap(ellinit([1,2,3,4,5]),nextprime(10^25))
%2 = 1231939791654
? ellap(ellinit([1,2,3,4,5]),nextprime(10^30))
%3 = 1790178944607137
? ellap(ellinit([1,2,3,4,5]),nextprime(10^35))
  ***   at top-level: ellap(ellinit([1,2,3
  ***                 ^--------------------
  *** ellap: bug in PARI/GP (Segmentation Fault), please report
  ***   Break loop: type 'break' to go back to GP
break> 

NOTE: To use ellap for big p, you must put the extracted data from seadata.tgz/data/* in local/share/pari, as explained here: http://pari.math.u-bordeaux.fr/packages.html

I'm reporting this bug upstream now.

This could hopefully fix the SEA segfault in Cygwin.

pari.listcreate no longer pre-allocates the entire list, so can't be used in the _pari_trap (out of memory) tests.

 After doing this, we also need to remove sea.gp, since it is included in pari now.

Here is a list of functions from decl.pxi that show up nowhere in the pari sources (using grep): http://sage.math.washington.edu/home/robertwb/scratch/robertwb/sage-4.4.4/missing_functions.txt

Just as a practicality could we put a date in the spkg's name?
It is a svn snapshot so we really want to know when it has been taken.
