Changes commited to PARI GIT during the last two weeks

mfeisenstein_i: optimize/simplify sum over divisors

12	17	src/basemath/mftrace.c

46- make sure factorlimit>= primelimit as documented

If not, then composites not detected in absZ_factor_limit_strict

Under gp -p 500000

install(absZ_factor_limit_strict,"GLD&")
absZ_factor_limit_strict(2181205156739883082072322466307767511435659730624751301062908246757922745017759415867401676157674404976691398629219689002172416000000000,10^6)

would include a composite at the end of the list

Flxq_log_index_cubic: avoid non-working models

78	1	src/basemath/Flxq_log.c

45- fix factoru_sign's batch trial division branch [#2648]

Two problems:
1) absZ_factor_limit_strict could include a composite in prime list
This created BIB (non-prime ideals and crash) in higher level calls

2) inconsistent behaviour wrt power test: cofactor not tested for
easy 2/3/5/7 powers in the batch trial division branch

- Fix bad logic in factoru_sign. No need for primality test: we have
enough information to decide.

- Fix inconsistent behaviour wrt power test: test cofactor for
  easy 2/3/5/7 powers in all branches. (Result would depend on
  tunings/primelimit in unpredicatble ways)

- For clarity, move the 2 snippets of code performing the power test out of
  the function
