[Vm-dev] PrimitiveOSError class name

[Alistair Grant]

Hi Eliot,

I'm just preparing a fogbugz issue and PR to add PrimitiveOSError to
Pharo and was wondering about the class name.

As you say in the class comments, errorName is typically set to
#'operating system error' (I haven't seen anything else), which makes
the class name and errorName somewhat redundant.

What do you think of renaming the class to PrimitiveError, which will
make it a bit more general and extensible in future?

Thanks,
Alistair
