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

ed5720c16830810e5829dfb9b66c96b2e24efc4f93aa5e38c7ff4150d31cfbbf

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.

lws minimal secure streams perf

The application goes to https://warmcat.com and reads index.html there.

The streamtype used is marked with a "perf": true policy, it returns additional rx payload marked with the LWSSS_FLAG_PERF_JSON flag containing a JSON rundown of the connection performance.

This builds both lws-minimal-secure-streams-perf that connects directly, and lws-minimal-secure-streams-perf-client that connects via the proxy, giving the same results.
