Fix GH-8538: SoapClient may strip parts of nmtokens

When stripping the namespace prefix, we can assume that this does not
contain any colons, while the rest of the name may contain colons.

the best case, with the stderr stream closed, it's just swallowed.

Stop closing stderr and stdout streams (#8569)

Extensions may (and do) write to stderr in mshutdown and similar. In
the best case, with the stderr stream closed, it's just swallowed.

However, some libraries will do things like try to detect color, and
these will outright fail and cause an error path to be taken.

range checks for integers which are not passed as int or double.

Closes GH-8407.
