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...

# NAME
CURLINFO_COOKIELIST - get all known cookies
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_COOKIELIST,
struct curl_slist **cookies);
~~~
# DESCRIPTION
Pass a pointer to a 'struct curl_slist *' to receive a linked-list of all
cookies curl knows (expired ones, too). Do not forget to call
curl_slist_free_all(3) on the list after it has been used. If there are no
cookies (cookies for the handle have not been enabled or simply none have been
received) the 'struct curl_slist *' is made a NULL pointer.
Since 7.43.0 cookies that were imported in the Set-Cookie format without a
domain name are not exported by this option.
# PROTOCOLS
HTTP(S)
# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* enable the cookie engine */
curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "");
res = curl_easy_perform(curl);
if(!res) {
/* extract all known cookies */
struct curl_slist *cookies = NULL;
res = curl_easy_getinfo(curl, CURLINFO_COOKIELIST, &cookies);
if(!res && cookies) {
/* a linked list of cookies in cookie file format */
struct curl_slist *each = cookies;
while(each) {
printf("%s\n", each->data);
each = each->next;
}
/* we must free these cookies when we are done */
curl_slist_free_all(cookies);
}
}
curl_easy_cleanup(curl);
}
}
~~~
# AVAILABILITY
Added in 7.14.1
# RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
