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_CURLU - URL in URL handle format

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CURLU, CURLU *pointer);

DESCRIPTION

Pass in a pointer to the URL handle to work with. The parameter should be a CURLU pointer. Setting CURLOPT_CURLU(3) explicitly overrides CURLOPT_URL(3).

CURLOPT_URL(3) or CURLOPT_CURLU(3) must be set before a transfer is started.

libcurl uses this handle and its contents read-only and does not change its contents. An application can update the contents of the URL handle after a transfer is done and if the same handle is used in a subsequent request the updated contents is used.

DEFAULT

The default value of this parameter is NULL.

PROTOCOLS

All

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  CURLU *urlp = curl_url();
  if(curl) {
    CURLcode res;
    CURLUcode ret;
    ret = curl_url_set(urlp, CURLUPART_URL, "https://example.com", 0);

    curl_easy_setopt(curl, CURLOPT_CURLU, urlp);

    res = curl_easy_perform(curl);

    curl_url_cleanup(urlp);
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 7.63.0.

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
