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_remove_handle - remove an easy handle from a multi session

SYNOPSIS

#include <curl/curl.h>

CURLMcode curl_multi_remove_handle(CURLM *multi_handle, CURL *easy_handle);

DESCRIPTION

Removes a given easy_handle from the multi_handle. This makes the specified easy handle be removed from this multi handle's control.

When the easy handle has been removed from a multi stack, it is again perfectly legal to invoke curl_easy_perform(3) on this easy handle.

Removing an easy handle while being in use is perfectly legal and effectively halts the transfer in progress involving that easy handle. All other easy handles and transfers remain unaffected.

It is fine to remove a handle at any time during a transfer, just not from within any libcurl callback function.

Removing an easy handle from the multi handle before the corresponding transfer is complete might cause libcurl to close the connection - if the state of it and the internal protocol handler deem it necessary. Otherwise libcurl keeps the connection alive in the connection pool associated with the multi handle, ready to get reused for a future transfer using this multi handle.

EXAMPLE

int main(void)
{
  CURLM *multi = curl_multi_init();
  int queued = 0;

  /* when an easy handle has completed, remove it */
  CURLMsg *msg = curl_multi_info_read(multi, &queued);
  if(msg) {
    if(msg->msg == CURLMSG_DONE) {
      /* a transfer ended */
      fprintf(stderr, "Transfer completed\n");
      curl_multi_remove_handle(multi, msg->easy_handle);
    }
  }
}

AVAILABILITY

Added in 7.9.6

RETURN VALUE

CURLMcode type, general libcurl multi interface error code.
