Upstream: r->upstream->length type change to off_t. Previous use of size_t may cause wierd effects on 32bit platforms with certain big responses transferred in unbuffered mode. Nuke "if (size > u->length)" check as it's not usefull anyway (preread body data isn't subject to this check) and now requires additional check for u->length being positive.
