databases/lmdb0: Add port for LMDB 0.9.x legacy ABI
LMDB 1.0 introduced an incompatible on-disk format change and subtle
API breakage: applications that compiled cleanly against 1.0 headers
could fail silently at run time. Known affected ports include dns/knot3,
mail/bogofilter, and mail/postfix; the postfix issue has been confirmed
upstream. Linux distributions such as Arch Linux have observed the same
breakage. Samba can also be affected in certain configurations.
Because the regression is not detectable in an -exp build run -- the
postfix failure only manifests at run time, and bogofilter was caught
only because post-build self-tests happen to exercise this path -- we
cannot rely on package builds to validate the 1.0 upgrade.
This commit introduces databases/lmdb0 as a holding port for the 0.9.35
release, pinned to the 0.x branch with PORTSCOUT=limit:^0. and mutually
conflicting with databases/lmdb, which retains 1.0. The two packages
cannot be installed simultaneously, but having lmdb0 available means:
