Andy Green 42dc817d8f ss: proxy: get rx flow control working
This fixes the proxy rx flow by adding an lws_dsh helper to hide the
off-by-one in the "kind" array (kind 0 is reserved for tracking the
unallocated dsh blocks).

For testing, it adds a --blob option on minimal-secure-streams[-client]
which uses a streamtype "bulkproxflow" from here

https://warmcat.com/policy/minimal-proxy-v4.2-v2.json

		"bulkproxflow": {
			"endpoint": "warmcat.com",
			"port": 443,
			"protocol": "h1",
			"http_method": "GET",
			"http_url": "blob.bin",
			"proxy_buflen": 32768,
			"proxy_buflen_rxflow_on_above": 24576,
			"proxy_buflen_rxflow_off_below": 8192,
			"tls": true,
			"retry": "default",
			"tls_trust_store": "le_via_dst"
		}

This downloads a 51MB blob of random data with the SHA256sum

The minimal-secure-streams --blob example client delays the download by
50ms every 10KiB it sees to force rx flow usage at the proxy.

It downloads the whole thing and checks the SHA256 is as expected.

Logs about rxflow status are available at LLL_INFO log level.
