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.

416a14fb85 Note about moving from Github. 
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.

PID check could be ommited:
 - on Linux when madvise(MADV_DONTFORK) is available. i.e. after the fork()
    mapped pages will not be available for child process.
 - in Windows where fork() not available.
