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

curl_multi_setopt - set options for a curl multi handle

SYNOPSIS

#include <curl/curl.h>

CURLMcode curl_multi_setopt(CURLM *multi_handle, CURLMoption option, parameter);

DESCRIPTION

curl_multi_setopt(3) is used to tell a libcurl multi handle how to behave. By using the appropriate options to curl_multi_setopt(3), you can change libcurl's behavior when using that multi handle. All options are set with the option followed by the parameter. That parameter can be a long, a function pointer, an object pointer or a curl_off_t type, depending on what the specific option expects. Read this manual carefully as bad input values may cause libcurl to behave badly. You can only set one option in each function call.

EXAMPLE


#define MAX_PARALLEL 45

  curl_multi_setopt(multi, CURLMOPT_MAXCONNECTS, (long)MAX_PARALLEL);
}

AVAILABILITY

Added in 7.15.4

RETURN VALUE

The standard CURLMcode for multi interface error codes. Note that it returns a CURLM_UNKNOWN_OPTION if you try setting an option that this version of libcurl does not know of.
