docs/libcurl: generate PROTOCOLS from meta-data
Remove the PROTOCOLS section from the source files completely and
instead generate them based on the header data in the curldown files.

It also generates TLS backend information for options marked for TLS as
protocol.

NAME

curl_easy_strerror - return string describing error code

SYNOPSIS

#include <curl/curl.h>

const char *curl_easy_strerror(CURLcode errornum);

DESCRIPTION

The curl_easy_strerror(3) function returns a string describing the CURLcode error code passed in the argument errornum.

Typically applications also appreciate CURLOPT_ERRORBUFFER(3) for more specific error descriptions generated at runtime.

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    /* set options */
    /* Perform the entire transfer */
    res = curl_easy_perform(curl);
    /* Check for errors */
    if(res != CURLE_OK)
      fprintf(stderr, "curl_easy_perform() failed: %s\n",
              curl_easy_strerror(res));
  }
}

AVAILABILITY

This function was added in libcurl 7.12.0

RETURN VALUE

A pointer to a null-terminated string.
