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_COOKIE - HTTP Cookie header

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIE, char *cookie);

DESCRIPTION

Pass a pointer to a null-terminated string as parameter. It is used to set one or more cookies in the HTTP request. The format of the string should be NAME=CONTENTS, where NAME is the cookie name and CONTENTS is what the cookie should contain.

To set multiple cookies, set them all using a single option concatenated like this: "name1=content1; name2=content2;" etc.

This option sets the cookie header explicitly in the outgoing request(s). If multiple requests are done due to authentication, followed redirections or similar, they all get this cookie passed on.

The cookies set by this option are separate from the internal cookie storage held by the cookie engine and they are not be modified by it. If you enable the cookie engine and either you have imported a cookie of the same name (e.g. 'foo') or the server has set one, it has no effect on the cookies you set here. A request to the server sends both the 'foo' held by the cookie engine and the 'foo' held by this option. To set a cookie that is instead held by the cookie engine and can be modified by the server use CURLOPT_COOKIELIST(3).

Using this option multiple times makes the last set string override the previous ones.

This option does not enable the cookie engine. Use CURLOPT_COOKIEFILE(3) or CURLOPT_COOKIEJAR(3) to enable parsing and sending cookies automatically.

The application does not have to keep the string around after setting this option.

If libcurl is built with PSL (Public Suffix List) support, it detects and discards cookies that are specified for such suffix domains that should not be allowed to have cookies. If libcurl is not built with PSL support, it has no ability to stop super cookies. PSL support is identified by the CURL_VERSION_PSL feature bit returned by curl_version_info(3).

DEFAULT

NULL, no cookies

PROTOCOLS

HTTP

EXAMPLE

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

    curl_easy_setopt(curl, CURLOPT_COOKIE, "tool=curl; fun=yes;");

    curl_easy_perform(curl);
  }
}

AVAILABILITY

If HTTP is enabled

RETURN VALUE

Returns CURLE_OK if HTTP is enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
