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_HTTPGET - ask for an HTTP GET request

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPGET, long useget);

DESCRIPTION

Pass a long. If useget is 1, this forces the HTTP request to get back to using GET. Usable if a POST, HEAD, PUT, etc has been used previously using the same curl handle.

When setting CURLOPT_HTTPGET(3) to 1, libcurl automatically sets CURLOPT_NOBODY(3) to 0 and CURLOPT_UPLOAD(3) to 0.

Setting this option to zero has no effect. Applications need to explicitly select which HTTP request method to use, they cannot deselect a method. To reset a handle to default method, consider curl_easy_reset(3).

DEFAULT

PROTOCOLS

HTTP(S)

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

    /* use a GET to fetch this */
    curl_easy_setopt(curl, CURLOPT_HTTPGET, 1L);

    /* Perform the request */
    curl_easy_perform(curl);
  }
}

AVAILABILITY

Along with HTTP

RETURN VALUE

Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
