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_escape - URL encodes the given string

SYNOPSIS

#include <curl/curl.h>

char *curl_escape(const char *string, int length);

DESCRIPTION

Obsolete function. Use curl_easy_escape(3) instead!

This function converts the given input string to a URL encoded string and return that as a new allocated string. All input characters that are not a-z, A-Z or 0-9 are converted to their "URL escaped" version (%NN where NN is a two-digit hexadecimal number).

If the length argument is set to 0, curl_escape(3) uses strlen() on string to find out the size.

You must curl_free(3) the returned string when you are done with it.

EXAMPLE

int main(void)
{
  char *output = curl_escape("data to convert", 15);
  if(output) {
    printf("Encoded: %s\n", output);
    curl_free(output);
  }
}

AVAILABILITY

Since 7.15.4, curl_easy_escape(3) should be used. This function might be removed in a future release.

RETURN VALUE

A pointer to a null-terminated string or NULL if it failed.
