docs: make each libcurl man specify protocol(s)
The mandatory header now has a mandatory list of protocols for which the
manpage is relevant.

Most man pages already has a "PROTOCOLS" section, but this introduces a
stricter way to specify the relevant protocols.

cd2nroff verifies that at least one protocol is mentioned (which can be
`*`).

This information is not used just yet, but A) the PROTOCOLS section can
now instead get generated and get a unified wording across all manpages
and B) this allows us to more reliably filter/search for protocol
specific manpages/options.

NAME

CURLINFO_QUEUE_TIME_T - time this transfer was queued

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_QUEUE_TIME_T,
                           curl_off_t *timep);

DESCRIPTION

Pass a pointer to a curl_off_t to receive the time, in microseconds, this transfer was held in a waiting queue before it started "for real". A transfer might be put in a queue if after getting started, it cannot create a new connection etc due to set conditions and limits imposed by the application.

See also the TIMES overview in the curl_easy_getinfo(3) man page.

All

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_off_t queue;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    res = curl_easy_perform(curl);
    if(CURLE_OK == res) {
      res = curl_easy_getinfo(curl, CURLINFO_QUEUE_TIME_T, &queue);
      if(CURLE_OK == res) {
        printf("Queued: %" CURL_FORMAT_CURL_OFF_T ".%06ld us", queue / 1000000,
               (long)(queue % 1000000));
      }
    }
    /* always cleanup */
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 8.6.0

RETURN VALUE

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