long story short: while testing -portable for the recent sockets commits
I noticed that gotwebd dies on the first request.

I've already committed a minimal fix: QSELEM__MAX was bigger than the
actual number of elements in the table -- my fault for forgetting to
remove PREVID -- so we read out of bounds and on alpine at least there
happen to be some zeroes... hello strcmp(NULL)!

This would fix it as well, but more importantly would have prevented the
error in the first place.
