[PATCH] test-url-normalize.c: Fix gcc errors and sparse warnings

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Sparse issues an "non-ANSI function declaration of function 'main'"
warning when NO_CURL is set. In order to suppress the warning, we
simply add the function prototype.

When NO_CURL and USE_CURL_MULTI are not defined, then gcc issues the
following error:

      CC test-url-normalize.o
  test-url-normalize.c: In function `run_http_options':
  test-url-normalize.c:49: error: `max_requests' undeclared (first use in this function)
  test-url-normalize.c:49: error: (Each undeclared identifier is reported only once
  test-url-normalize.c:49: error: for each function it appears in.)
  make: *** [test-url-normalize.o] Error 1

In order to fix the error, we simply protect the use of the 'max_requests'
variable with an preprocessor conditional.

Hi Kyle,

When you next update the patches in your 'km/http-curl-config-per-url'
branch, could you please squash this (or something like it) into the
relevant patches.

Thanks!

ATB,
Ramsay Jones
