Subject: Toss 'const' in anywhere the compiler doesn't complain about, thus identifying
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=859be6c9dfba1dab8e7f1036d24b90c365c59bec;p=openbsd

Toss 'const' in anywhere the compiler doesn't complain about, thus identifying
places that *should* be const but currently aren't and preventing the rot from
spreading further while those issues are dealt with.

No functional change.
