Marc Hoersken fbf3560886 curl_schannel: Removed buffer limit and optimized buffer strategy
Since there are servers that seem to return very big encrypted
data packages, we need to be able to handle those without having
an internal size limit. To avoid the buffer growing to fast to
early the initial size was decreased and the minimum free space
in the buffer was decreased as well.
