Update to Wine 1.9.2. This includes the following changes:

• GStreamer 1.0 support.
• Support for SHA hashes in BCrypt.
• Synthesizing bold glyphs also for bitmap fonts.
• Underlines support in DirectWrite.
• Still more Shader Model 4 instructions.
• Various bug fixes.

It also brings quite many changes on the packaging side (libraries),
both for vanilla builds and ones with option STAGING (and hence the
wine-staging port).

No longer set USE_AUTOTOOLS=autoconf for option STAGING; it's not
used currently.
