Perl_set_context() allow NULL argument
A recent commit of mine made threads set their context to NULL when in
the late stages of being freed - previously they were set briefly to the
main thread's context. In theory at that point the context shouldn't be
used at all; if accessed, it likely indicates a bug. I decided that
dereffing a null pointer was more likely to obviously show up a fault
than randomly accessing a different thread's context at this point.
This worked out on platforms where PERL_SET_CONTEXT() is implemented
directly; on platforms where it falls back to Perl_set_context(), it was
assert-failing due to the NULL argument.
