http module needs httpapi.lib, not winhttp.lib

[tom-bowles]

I think this line in build.rs:

("http", &["guiddef", "minwinbase", "minwindef", "sspi", "winnt", "ws2def"], &["winhttp"]),

should be:

("http", &["guiddef", "minwinbase", "minwindef", "sspi", "winnt", "ws2def"], &["httpapi"]),

When I try to use httpapi, I found this question too.

And another question is :

winapi-rs/src/um/http.rs

Lines 853 to 856 in f823e7e

	pub fn HttpCreateHttpHandle(
	pReqQueueHandle: HANDLE,
	Reserved: ULONG,
	) -> ULONG;

According to https://docs.microsoft.com/en-us/windows/win32/api/http/nf-http-httpcreatehttphandle

HTTPAPI_LINKAGE ULONG HttpCreateHttpHandle(
  OUT PHANDLE RequestQueueHandle,
  ULONG       Reserved
);

pReqQueueHandle shoud be PHANDLE not HANDLE

It is highly appreciated if you could fix these.Thanks
