The define does not originate from configure, so it should not
have a name that is CONFIG_-prefixed.

20 ms is the default in the libopus encoder, and gives better
quality than 10 ms.

Previously, if neither of the checks for the closesocket function
succeeded, we still kept winsock2.h and networking in general
enabled.

When targeting the WinRT API subset, the winsock2.h header is
available (making the check for it succeed, giving the impression
that winsock is available), but tests that actually try to use
such a function will fail. In this case, disable the winsock2.h
feature and networking in general, as if the winsock2.h header
test would have failed in the first place.

The new code is faster and reuses the previous state in case of
multiple calls.

The previous code could easily end up in near-infinite loops,
if the difference between two clock() calls never was larger than
1.

This makes fate-parseutils finish in finite time when run in wine,
if CryptGenRandom isn't available (which e.g. isn't available if
targeting Windows RT/metro).

Patch originally by Michael Niedermayer but with some modifications
by Martin Storsjö.

The freetype tutorial suggests to use #include FT_FREETYPE_H.

It should be forward compatible with newer freetype.
