[PATCH 0/1] MR6644: Draft: msvcrt: Initialize locale data in new threads.

[Bernhard Übelacker (＠bernhardu)]

This attempts to initialize the thread data more like in the mainthread,
which does in msvcrt_init_locale a call to _setmbcp, which finally
fills the cached_locale member of the thread data.
