function _uc_file_time_accumulate_equation in Ubercart 8.4

Same name and namespace in other branches

1. 6.2 uc_file/uc_file.module \_uc_file_time_accumulate_equation()
2. 7.3 uc_file/uc_file.module \_uc_file_time_accumulate_equation()

Accumulates numeric limits (as of now, download and address).

We follow a couple simple rules here...

If proposing no limit, it always overrides current.

If proposal and current are limited, then replace with the new expiration.

If current is unlimited, then a limited proposal will only overwrite in the case of the forced overwrited explained above.
