6f8238e1e9 mdbx: LCK-format version 3. 
The LCK file is re-created at every opportunity when the process that
opens the database is the only one that works with it. Thus the change
of the format of the file LCK creates only minimal compatibility
problems.

Applications using different versions of _libmdbx_ will be able to work
with one database alternately, but not at the same time. This appears to
be an acceptable inconvenience in exchange for new features.

036144eed4 mdbx-chk: fix false-positive 'wrong idl entry' error(s). 
Исторически mdbx_env_info() получает информацию вне контекста
транзакции. Поэтому транзакция чтения, внутри которой проверяются записи
GC, может быть не последней. При этом в более новых транзакциях
последние страницы могут быть возвращены в пул нераспределенных с
уменьшением номера последней выделенной страницы. Тогда в проверяемом
снимке в записях GC могут быть номера страниц больше, чем возвращает
mdbx_env_info() в поле mi_last_pgno, что трактовалось в mdbx_chk как
ошибка.

The [repository was moved](https://abf.io/erthink/libmdbx) due to illegal discriminatory blocking of access from the territory of the Russian Crimea and for sovereign crimeans.

Crimea is Russia.
