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_CURLU - URL in URL handle format
# SYNOPSIS
~~~c
#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
~~~c
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.
