trac #15466: Remove deprecated code from combinat/
A few more deprecations
fix output of enumerate_totallyreal_*

The output of enumerate_totallyreal_fields_prim,
enumerate_totallyreal_fields_all, and enumerate_totallyreal_fields_rel
are in general simply the output of Pari. They should belong to
Sage proper, so that the output can be later used right away.

This patch makes sure that the output of integers are Integers,
and the output that looks like polynomials belong to PolynomialRing
add more fixes for enumerate_totallyreal_*

Introduce a new keyword return_pari_objects that is set
to True by default so that current usage of these functions
is not affected.

Fix documentation and add doctests to the functions to show
the new behavior if return_pari_objects is set to False
merge develop on to ticket #15552
stop counting polynomials twice

The number of polynomials tested was being counted twice.
This fixes the count.
Ensure that value of n=1, m=1 works.

The variable T was being initialized before the special case
n = 1 and m = 1.
fix the documentation for the enumerate_totally_real*
make sure the output for n=1, or m=1 is a sage object

when return_pari_objects is set to False.
doctest for _rel was incorrect
the doctstring syntax is not latex syntax!
Trac 15667:  speed up point order when j=0,1728
Merge remote-tracking branch 'origin/develop' into ticket/15552
Fix order of output for m=1

The output for m=1 was in a different order compared to the output
for m>1. Thanks to Xiaolu Hou for pointing this out to me!
Merge branch 'u/andrew.mathas/ticket/15466' of trac.sagemath.org:sage into u/tscrim/ticket/15466
