possible solution for steam #1

while trying to solve the same issue i noticed that the calls can return errno 75 and non-zero and even if you override the values steam bails out because of that.

clearing errno to 0 and returning 0 in the hooks might solve the problem. I have my own set of hooks doing this and they seem to work so far

... also it seems that the highest supported value for blocks * blocksize is (INT_MAX>>1) rather than INT_MAX, otherwise some games will still see no space

nevermind, (INT_MAX<<9) also works and reports 1TB free

but yeah, clearing errno and returning 0 should fix it

thanks for the input, sadly i can't test it anymore though because my specific issue is fixed by steam, but if you want to send a PR you tested i'll merge it, otherwise i can try to implement it later but can't test it then

thing is though, steam was not only failing but actually in some places still showing the wrong values, as if it was clearing LD_PRELOAD while it spawned some of its helper processes maybe. so no idea if that'll actually help in the end even though it theoretically should
