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_QUICK_EXIT - allow to exit quickly

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_QUICK_EXIT,
                          long value);

DESCRIPTION

Pass a long as a parameter, 1L meaning that when recovering from a timeout, libcurl should skip lengthy cleanups that are intended to avoid all kinds of leaks (threads etc.), as the caller program is about to call exit() anyway. This allows for a swift termination after a DNS timeout for example, by canceling and/or forgetting about a resolver thread, at the expense of a possible (though short-lived) leak of associated resources.

int main(void)
{
  CURL *curl = curl_easy_init();

    ret = curl_easy_perform(curl);
  }
}

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