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_MAX_SEND_SPEED_LARGE - rate limit data upload speed

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAX_SEND_SPEED_LARGE,
                          curl_off_t maxspeed);

DESCRIPTION

Pass a curl_off_t as parameter with the maxspeed. If an upload exceeds this speed (counted in bytes per second) the transfer pauses to keep the average speed less than or equal to the parameter value. Defaults to unlimited speed.

This is not an exact science. libcurl attempts to keep the average speed below the given threshold over a period time.

If you set maxspeed to a value lower than CURLOPT_UPLOAD_BUFFERSIZE(3), libcurl might "shoot over" the limit on its first send and still send off a full buffer.

This option does not affect transfer speeds done with FILE:// URLs.

DEFAULT

0, disabled

PROTOCOLS

All except file://

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode ret;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    /* cap the upload speed to 1000 bytes/sec */
    curl_easy_setopt(curl, CURLOPT_MAX_SEND_SPEED_LARGE, (curl_off_t)1000);
    /* (set some upload options as well!) */
    ret = curl_easy_perform(curl);
  }
}

AVAILABILITY

Added in 7.15.5

RETURN VALUE

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