Revert "mandatory anonymous section identifier"

This reverts commits:
df72af474075 "mandatory anonymous section identifier"
2eb9c097e392 "cli: remove now-defunct UCI_FLAG_EXPORT_NAME support"
fe45f97302cb "test: adjust for auto-naming anonymous sections"

After some discussion we came to the conclusion that we need a different
fix.
