[Bug debuginfod/27982] added DEBUGINFOD_MAXSIZE and DEBUGINFOD_MAXTIME

[Noah Sanci]

Hello,

> Why have MAXTIME default to LONG_MAX? Which is long, but different on
> different arches 32/64bit. If MAXSIZE == 0 means infinite, why not make
>  MAXTIME=0 the same for consistency?

Fixed.

> The bug suggests to also check the Content-Length header on reciept (in
> case the server didn't support or respect the X-DEBUGINFOD-MAXSIZE
> header. Did you try to implement that?

Fixed.

> I believe various error handling goto out1 should be goto out2 (after
> your duplicate urls patch). Could you double check that?

Fixed.
