8- normlp(, oo): support components equal to oo or -oo

characteristic polynomial: remove 2 calls to fix_pol in dim = 1 cases

12	8	src/basemath/alglin2.c

fix_pol: handle correctly the case gvar2 == NO_VARIABLE

5	1	src/basemath/alglin2.c

algebras: update bench output

2	2	src/test/32/algebras

charpoly variants: don't create invalid t_POL.

Now always compute charpoly(M, v) as charpoly(M, fetch_var_higher())(v)

26	26	src/basemath/alglin2.c
2	4	src/test/32/charpoly

fix swap_vars(): don't create an invalid t_POL

31	20	src/basemath/gen3.c
13	17	src/basemath/polarit3.c
1	1	src/headers/paripriv.h

fix bench input

4	4	src/test/in/padic

1- subst: use fast RgX_affine function to compute P(a*x+b)

+ fix RgX_affine (assumed b t_INT)
+ let RgX_tranlate call ZX_translate if possible
+ let ZX_translate do a simple copy if b = 0 (very frequent in bench!)

The patch is correct but breaks the lfun bench by exposing an independent
bug in nfcompositum (invalid t_POL whose coefficients are t_POL in
variables of higher priority). To be fixed in a followup commit.
