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_mime_addpart - append a new empty part to a mime structure

SYNOPSIS

#include <curl/curl.h>

curl_mimepart *curl_mime_addpart(curl_mime *mime);

DESCRIPTION

curl_mime_addpart(3) creates and appends a new empty part to the given mime structure and returns a handle to it. The returned part handle can subsequently be populated using functions from the mime API.

mime is the handle of the mime structure in which the new part must be appended.

EXAMPLE

int main(void)
{
  curl_mime *mime;
  curl_mimepart *part;

  CURL *curl = curl_easy_init();
  if(curl) {
    /* create a mime handle */
    mime = curl_mime_init(curl);

    /* add a part */
    part = curl_mime_addpart(mime);

    /* continue and set name + data to the part */
    curl_mime_data(part, "This is the field data", CURL_ZERO_TERMINATED);
    curl_mime_name(part, "data");
  }
}

AVAILABILITY

As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.

RETURN VALUE

A mime part structure handle, or NULL upon failure.
