Allow any length thread names for WIN32

Dynamically allocate the string space for thread
name in WIN32 (ntthread.c) thread space.  This
makes the WIN32 more consistent with the other
environments.  It also addresses WIN32 issue of
the print width of 17 being used and only having
space for 16 characters in the fixed allocation.
