David Faure 574e5cf9c5 Add qunsetenv(), next to qputenv() and friends. ... The existing tst_qgetputenv shows that qputenv with an empty value doesn't lead to the same result on Windows and on Unix, and there was no way to fully delete an env var on Unix (which is needed for some env vars where not-set and empty are different, such as TZ, see `man tzset`). This is also why qglobal has qEnvironmentVariableIsSet() vs qEnvironmentVariableIsEmpty(), on the getter side. Qt4's ifdefs around unsetenv in qapplication_x11.cpp show that this is needed within Qt too (although this particular startup notification code has to be re-imported into Qt5 still).
