Performance drop with 4.8 release

[Henrik Andersson]

Hi,

We have seen a drop in performance using libtasn1 4.8 release when our
tool works over a set of crls. Our input crl has 47815 entries and the
time to process over this set is doubled compared to 4.7.

We have identified that the offending commit is
62cb6fab75ee9a4fc2925104896980d40862a89f.

As we experience there are obviously a performance boost with the
_asn1_find_up() optimization, which was reverted in the commit above.


Kind Regards,

Henrik Andersson (Cendio AB)
