websocket: introduce blocking sends

When using `curl_ws_send()`, perform a blocking send of the data under
the following conditions:

- the websocket is in raw mode and the call is done from within a curl
callback. A partial write of the data could subsequently mess up the
ws framing, as a callback has a hard time handling this.

- the websocket is encoding the data itself, has added it to its
internal sendbuf. A partial flush of the buffer has unclear semantics
for the caller, as they will have no idea what to send again.

Fixes WebSockets tests with CURL_DBG_SOCK_WBLOCK=90 set.

curl: --help [option] displays documentation for given cmdline option

Since the documentation text blob might be gzipped, it needs to search
for what to output in a streaming manner. It then first searches for
"\nALL OPTIONS".

Then, it looks for the start to display at "\n -[option]" and stops
again at "\n -". Except for the last option in the man page, which
ends at "\nFILES" - the subtitle for the section following all options
in the manpage.
