Logging: make qEmergencyOut() not allocate from the heap

Commit 6e6b74c0 introduced heap allocation in the form of
QString::fromLatin1().utf16() into qEmergencyOut(), a function
that's called in OOM situations and in cases where another
exception is still in flight.

Luckily, QString::fromLatin1().utf16() is just a funny way of
copying an array of chars into an array of wchar_ts, so we do
that manually now and use a static wchar_t buffer. While at it,
also throw text elision into the mix.

This commit also fixes the message passed to _CrtDbgReportW().
What should be displayed is the emergency_buf, not the format
string.

Also remove a similar allocation in qt_message_output().
