Update buckygen package for the sage-git directory layout
Add residue_field() method to polynomials over GF(p)
bugfix: root_extension_embedding didn't always produce the correct embedding, replaced the method by a slower but more reliable one
support action of elements on elements by conjugation
support an argument (the power) for the translation (this gives a performance gain for large or negative powers)
Use pari_ffelt for residue fields
Update citation HKW2014 to reflect new revision of that article on arxiv.org

Trac #13627: implement xgcd for padics

Currently, there is no xgcd for padic numbers:
{{{
sage: R = Zp(3)
sage: R.one().xgcd(R.zero())
AttributeError: 'sage.rings.padics.padic_capped_relative_element.pAdicCa
ppedRelativeElement' object has no attribute 'xgcd'
}}}

The attached patch implements it.

Trac #16951: Make random_point() for elliptic curves over a finite field uniform

Currently, 2-torsion points are twice as likely as other points to be
"randomly" chosen and the point at infinity is chosen with probability
1/(q+1) regardless of the number of points on E(GF(q)).

Trac #16915: Remove workaround for old Pyrex in element_givaro.pyx

This is just a small thing I noticed while reading this code. I am also
adding a few doctests to check for #16807 for Givaro finite fields.
