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...

Closes #12730

NAME

CURLOPT_INFILESIZE_LARGE - size of the input file to send off

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE_LARGE,
                          curl_off_t filesize);

DESCRIPTION

When uploading a file to a remote site, filesize should be used to tell libcurl what the expected size of the input file is. This value must be passed as a curl_off_t.

For uploading using SCP, this option or CURLOPT_INFILESIZE(3) is mandatory.

To unset this value again, set it to -1.

When sending emails using SMTP, this command can be used to specify the optional SIZE parameter for the MAIL FROM command.

This option does not limit how much data libcurl actually sends, as that is controlled entirely by what the read callback returns, but telling one value and sending a different amount may lead to errors.

EXAMPLE

#define FILE_SIZE 123456

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    curl_off_t uploadsize = FILE_SIZE;

    curl_easy_setopt(curl, CURLOPT_URL,
                     "ftp://example.com/destination.tar.gz");

    curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

    curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, uploadsize);

    curl_easy_perform(curl);
  }
}

AVAILABILITY

SMTP support added in 7.23.0

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
