Johannes Altmanninger 2fa98ec20c Fix deadlock when importing universal LC_* variable
The C++ version of this code simply copied the entire uvar table.
Today we take a reference. It's not clear which one is better.

Removal of locale variables like LC_ALL triggers variable change handlers
which call EnvStackImpl::get. This deadlocks because we still hold the lock
to protect the reference to all uvars.  Work around this.

Closes #10513
