hstore: Tighten key/value parsing check for whitespaces
isspace() can be locale-sensitive depending on the platform, causing
hstore to consider as whitespaces characters it should not see as such.
For example, U+0105, being decoded as 0xC4 0x85 in UTF-8, would be
discarded from the input given.
This problem is similar to 9ae2661, though it was missed that hstore
can also manipulate non-ASCII inputs, so replace the existing isspace()
calls with scanner_isspace().
This problem exists for a long time, so backpatch all the way down.
