nexus: Move persistent data

When any configuration is done to the nexus server is persists that data
to the sonatype-work directory. Also all maven artifacts are downloaded
into that directory too. So if you want to have that same setup after
upgrading, the sonatype-work directory needs to be somewhere common all
versions. This commit patches nexus to look for that data in var/nexus.

Closes #19361.

Closes #20092.

berkeley-db: --enable-compat185 by default

Our berkeley db shadows the OS's berkeley db 1.x, making it impossible
to build software that only builds on 1.x (e.g. opensmtpd).
The --enable-compat185 switch enables a 1.x compatibility mode, which
shouldn't have any downsides and is the standard in other package
managers. (One wonders why it isn't on by default if so.)
couchdb: replace DATA patch with inreplace

Geocouch uses this formula to get the couchdb source, and this means we
cannot use a DATA patch here since it only exists for the executing
file.

Fixes #20073.
