Because WINENV is limited (32767 bytes), and HOSTENV can be much larger,
a whitelisting approach is used to keep WINENV as small as possible.
Currently, only the following envvars are propagated from the host env to WINENV
WINEPATH, WINEPWD, WINEHOME, WINETEMP, WINETMP, WINEQT_, WINEVK_, WINEXDG_SESSION_TYPE
Moreover, the NIXENV (env for running wine processes - not applications) on the
host system is not produced from WINENV anymore, but the global ENV
is propagated to all wine processes and threads.
This might be an alternative approach to MR!5231, MR!6140, bug #56941
and should provide a more deterministic behaviour of wine, because unrelated
envvars do have no influence on the env for running windows applications.
Initial tests (winemine, notepad, cmd, etc) seem to run fine, but some envvars might need additional
consideration. XVDK_* was mentioned, WINE*, MESA_*, VK_*, QT_*, LIBGL_* are other suspects.
Moreover, this is my first merge request, so your feedback is highly appreciated.
