curl_str[n]equal.md: tidy up text to make them stand-alone

Previously this was one single manpage for two functions but as they are
two separate ones since a while back, they should each clearly document
their single specific functions.

NAME

curl_strequal - compare two strings ignoring case

SYNOPSIS

#include <curl/curl.h>

int curl_strequal(const char *str1, const char *str2);

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.

This function uses plain ASCII based comparisons completely disregarding the locale - contrary to how strcasecmp and other system case insensitive string comparisons usually work.

This function is provided by libcurl to enable applications to compare strings in a truly portable manner. There are no standard portable case insensitive string comparison functions. This function works 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");
}

AVAILABILITY

Always

RETURN VALUE

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