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
CURLOPT_COOKIESESSION - start a new cookie session
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIESESSION, long init);
~~~
# DESCRIPTION
Pass a long set to 1 to mark this as a new cookie "session". It forces libcurl
to ignore all cookies it is about to load that are "session cookies" from the
previous session. By default, libcurl always loads all cookies, independent if
they are session cookies or not. Session cookies are cookies without expiry
date and they are meant to be alive and existing for this "session" only.
A "session" is usually defined in browser land for as long as you have your
browser up, more or less. libcurl needs the application to use this option to
tell it when a new session starts, otherwise it assumes everything is still in
the same session.
# DEFAULT
0
# PROTOCOLS
HTTP
# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
/* new "session", do not load session cookies */
curl_easy_setopt(curl, CURLOPT_COOKIESESSION, 1L);
/* get the (non session) cookies from this file */
curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "/tmp/cookies.txt");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
