LibHTTP: Bump max HTTP header size up to 32KiB

Browse source 
Apparently discord likes to feed us headers as big as 6KiB, so clearly
there are large headers out there in the wild.
For reference, Apache's limit is 8KiB, and IIS's limit is 16KiB (this
limit is not defined by the spec, so nothing can stop a server from
sending massive headers - sadly)
