For downloads and uploads that fail because too few servers are connected, we should report that rather than reporting a problem with the specific file.

k may differ between files in the case of downloads, but if we find no less than k shares and fewer than the configured shares.needed servers are connected, then the failure to find shares is probably due to lack of servers. For uploads to succeed, at least shares.happy servers must be connected.

For downloads and uploads that fail because too few servers are connected, we should report that rather than reporting a problem with the specific file. k may differ between files in the case of downloads, but if we find ~~no~~ less than k shares and fewer than the configured `shares.needed` servers are connected, then the failure to find shares is probably due to lack of servers. For uploads to succeed, at least `shares.happy` servers must be connected.
