Refactor all the fetch code so that there are not 6 slightly different
versions of it but one that does it all.
The targets that have been extracted are:
- check-vulnerable
- do-fetch
- fetch-list
- fetch-url-list-int
- fetch-urlall-list
- checksum.
- makesum.
- check-checksum-algorithms
Run the fetch code directly from make makesum instead of calling make
fetch, this is because some port change the options with OPTIONS_*_FORCE
when make(makesum) to be able to add all distfiles in one go, which was
a nice, non working, idea.
