[Bug 286107] ports-mgmt/pkg: improvement request: only install files whose checksum have changed

While the .pkg file to be installed from has
known good content for any checksum like
information (no support of modifications to the
contents), a live target file system's file vs.
the /var/db/pkg/local.sqlite content for that
file can be an issue for which files still match
vs. which do not. That can include temporary bug
fixes that were not just edits of text files.

Allowing for local security updates and such
being replaced by pkg could lead to not wanting
deletion of old files by pkg that do not match
the original old files, for example. .pkgsave
and .pkgnew files are examples of ending up
with both old and new files (by content)
already.

Because of such, checksumming of the live files
could well be involved and 3 checksums for a
file could be compared for figuring out what to
do. Permissions/protections/flags/ownership/. . .
changes are also involved overall.
