curldown: fixups
- make DEFAULT sections less repetitive

- make historic mentions use HISTORY

- generate the protocols section on `# %PROTOCOLS%` instead of guessing
  where to put it

- generate the availability section on `# %AVAILABILITY%` instead of
  guessing where to put it

- make the protocols section more verbose

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

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%

RETURN VALUE

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