Add htons/htonl definitions and implementations
https://bugs.webkit.org/show_bug.cgi?id=98054

Reviewed by Darin Adler.

Source/WebCore:

Update users of htons and friends to use new wtf/ByteOrder.h header.

No new tests - just refactoring.

Source/WTF:

For parsing or serializing binary data, byte order matters. The canonical htons/htonl/
ntohs/ntohl functions are not present everywhere, so implementations are proliferating in
parsers. Expose a new WTF header (wtf/ByteOrder.h) that includes the standard
implementations on UNIX-like OSs and provides basic inlined implementations on Windows.

* GNUmakefile.list.am:
* WTF.gypi:
* WTF.pro:
* WTF.vcproj/WTF.vcproj:
* WTF.xcodeproj/project.pbxproj:
* wtf/ByteOrder.h: Added.
(WTF::wswap32): Inline functions so arguments are only evaluated once.
(WTF::bswap32):
(WTF::bswap16):
(ntohs): Inline functions on OS(WINDOWS) to match macros on OS(UNIX)
(htons):
(ntohl):
(htonl):
* wtf/CMakeLists.txt:
