wsemul_vt100_subr: complete the refactoring from 2010
In 1.20 refactoring, functions in this file were changed to accept a
pointer to the new base class instead of the full emuldata:
  -wsemul_vt100_foo(struct wsemul_vt100_emuldata *edp, ...)
  +wsemul_vt100_foo(struct vt100base_data *edp, ...)
but the argument name was not changed.  While this saved on the diff
churn back then, it created a rather unfortunate situation where the
same emulation state variables are referred to differently in this
file and other vt100 emulation files.  Complete that old change by
renaming the base class arguments to match the variable name used for
it in other files.

Same object code is generated.
