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.

Closes #13175

NAME

curl_strequal, curl_strnequal - case insensitive string comparisons

SYNOPSIS

#include <curl/curl.h>

int curl_strequal(const char *str1, const char *str2);
int curl_strnequal(const char *str1, const char *str2, size_t length);

DESCRIPTION

The curl_strequal(3) function compares the two strings str1 and str2, ignoring the case of the characters. It returns a non-zero (TRUE) integer if the strings are identical.

The curl_strnequal() function is similar, except it only compares the first length characters of str1.

These functions are provided by libcurl to enable applications to compare strings in a truly portable manner. There are no standard portable case insensitive string comparison functions. These two work on all platforms.

EXAMPLE

int main(int argc, char **argv)
{
  const char *name = "compare";
  if(curl_strequal(name, argv[1]))
    printf("Name and input matches\n");
  if(curl_strnequal(name, argv[1], 5))
    printf("Name and input matches in the 5 first bytes\n");
}

AVAILABILITY

Always

RETURN VALUE

Non-zero if the strings are identical. Zero if they are not.
