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

curl_easy_option_by_name - find an easy setopt option by name

SYNOPSIS

#include <curl/curl.h>

const struct curl_easyoption *curl_easy_option_by_name(const char *name);

DESCRIPTION

Given a name, this function returns a pointer to the curl_easyoption struct, holding information about the curl_easy_setopt(3) option using that name. The name should be specified without the "CURLOPT_" prefix and the name comparison is made case insensitive.

If libcurl has no option with the given name, this function returns NULL.

EXAMPLE

int main(void)
{
  const struct curl_easyoption *opt = curl_easy_option_by_name("URL");
  if(opt) {
    printf("This option wants CURLoption %x\n", (int)opt->id);
  }
}

AVAILABILITY

This function was added in libcurl 7.73.0

RETURN VALUE

A pointer to the curl_easyoption struct for the option or NULL.
