lib: make protocol handlers store scheme name lowercase

- saves a lowercase operation when the "[scheme]_proxy" name is
  generated
- appears less "shouting"
- update test 970, 972, 1438 and 1536

Closes #13553

NAME

CURLINFO_SCHEME - get the URL scheme (sometimes called protocol) used in the connection

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SCHEME, char **scheme);

DESCRIPTION

Pass a pointer to a char pointer to receive the pointer to a null-terminated string holding the URL scheme used for the most recent connection done with this CURL handle.

The scheme pointer is NULL or points to private memory. You MUST NOT free - it gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.

The returned scheme might be upper or lowercase. Do comparisons case insensitively.

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    res = curl_easy_perform(curl);
    if(res == CURLE_OK) {
      char *scheme = NULL;
      curl_easy_getinfo(curl, CURLINFO_SCHEME, &scheme);
      if(scheme)
        printf("scheme: %s\n", scheme); /* scheme: HTTP */
    }
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 7.52.0

RETURN VALUE

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