docs: introduce "curldown" for libcurl man page format

curldown is this new file format for libcurl man pages. It is markdown
inspired with differences:

- Each file has a set of leading headers with meta-data
- Supports a small subset of markdown
- Uses .md file extensions for editors/IDE/GitHub to treat them nicely
- Generates man pages very similar to the previous ones
- Generates man pages that still convert nicely to HTML on the website
- Detects and highlights mentions of curl symbols automatically (when
  their man page section is specified)

tools:

- cd2nroff: converts from curldown to nroff man page
- nroff2cd: convert an (old) nroff man page to curldown
- cdall: convert many nroff pages to curldown versions
- cd2cd: verifies and updates a curldown to latest curldown

This setup generates .3 versions of all the curldown versions at build time.

CI:

Since the documentation is now technically markdown in the eyes of many
things, the CI runs many more tests and checks on this documentation,
including proselint, link checkers and tests that make sure we capitalize the
first letter after a period...

Closes #12730

NAME

CURLOPT_WS_OPTIONS - WebSocket behavior options

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WS_OPTIONS, long bitmask);

DESCRIPTION

Pass a long with a bitmask to tell libcurl about specific WebSocket behaviors.

To detach a WebSocket connection and use the curl_ws_send(3) and curl_ws_recv(3) functions after the HTTP upgrade procedure, set the CURLOPT_CONNECT_ONLY(3) option to 2L.

Available bits in the bitmask

CURLWS_RAW_MODE (1)

Deliver "raw" WebSocket traffic to the CURLOPT_WRITEFUNCTION(3) callback.

In raw mode, libcurl does not handle pings or any other frame for the application.

DEFAULT

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "ws://example.com/");
    /* tell curl we deal with all the WebSocket magic ourselves */
    curl_easy_setopt(curl, CURLOPT_WS_OPTIONS, (long)CURLWS_RAW_MODE);
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
