Review request for Viewer.
Summary
-------
Without this patch, getLindenUserDir() is sometimes used without
checking if it returns an empty value, resulting in trying to open
an empty file and then gracefully recovering from that. So, this
patch doesn't really fix a bug. However it might prevent one in the
future. Note that this DID lead to a bug in Viewer 1 code, so it's
possible. The main threat is that some singleton class that uses
getLindenUserDir (indirectly) is instantiated before logging in:
A singleton is only created once and when it is initialized with
an empty getLindenUserDir() then that can remain.
This patch aborts when the viewer is compiled in debug mode (not
in release mode, when it will do what it did before this patch)
and when getLindenUserDir() is called before it was initialized,
unless the developer explicitely passes 'true' (empty_ok) to
getLindenUserDir, signaling that they considered the possibility
that the function is being called before the user logged in.
This addresses bug VWR-24333.
