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

CURLMOPT_PIPELINING_SERVER_BL - pipelining server block list

SYNOPSIS

#include <curl/curl.h>

CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING_SERVER_BL,
                            char **servers);

DESCRIPTION

No function since pipelining was removed in 7.62.0.

Pass a servers array of char *, ending with a NULL entry. This is a list of server types prefixes (in the Server: HTTP header) that are blocked from pipelining, i.e server types that are known to not support HTTP pipelining. The array is copied by libcurl.

Note that the comparison matches if the Server: header begins with the string in the block list, i.e "Server: Ninja 1.2.3" and "Server: Ninja 1.4.0" can both be blocked by having "Ninja" in the list.

Pass a NULL pointer to clear the block list.

DEFAULT

The default value is NULL, which means that there is no block list.

PROTOCOLS

EXAMPLE

static char *server_block_list[] =
{
  "Microsoft-IIS/6.0",
  "nginx/0.8.54",
  NULL
};
int main(void)
{
  CURLM *m = curl_multi_init();
  curl_multi_setopt(m, CURLMOPT_PIPELINING_SERVER_BL, server_block_list);
}

AVAILABILITY

Added in 7.30.0

RETURN VALUE

Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not.
