1740f8227a mdbx: rework copy-with-compactification. 
Кроме небольшого рефакторинга здесь реализуется более регулярный способ
обхода дерева при копировании с компактификаций. В частности, полная
инициализация курсоров позволяет выполнять больше проверок/контроля
структуры БД и избавиться от флажка CC_COPYING.

Beside a small refactoring, a more regular way of traversing the tree
when copying with compactification is implemented here. In particular,
full initialization of cursors allows to perform more checks/control of
the DB structure and get rid of the CC_COPYING flag.

720b4d56be mdbx: bigfoot feature. 
Chunking long list of retired pages during huge transactions commit
to avoid use sequences of pages:
 - splits a long retired page-number-list into chunks
   which fits one per single overflow/large page;
 - this requires a few unique id for keys
   for create such records into GC/freeDB;
 - just use the necessary subsequent IDs following the current
   transaction ID and then take the last of ones to update a meta-page.

Thus avoids using/allocating/searching a sequence of free pages
but just increase txnid more than one during the commit
a huge write transaction with a long retired-pages-list.

that affects only debug builgs (with enabled assertions) and only when the added
code catch a incoherency of unified page/buffer cache.

another thread opened a dbi-handle(s) between the two aforementioned events.

71d07b3a8e mdbx: adding cursors tracking/lists for read-only transactions. 
Briefly, this commit fixes a missed flaw:
 - Cursor tracking is required to replacing shaded pages and adjusting the positions in writing transactions;
 - Thus, historically, an internal linked list was maintained for a read-write transactions, but not for a read-only.
   For this reason, the API for using cursors should be different for writing and reading transactions;
 - However, the libmdbx's API has been significantly improved, including the ability to reuse cursors and a uniform cursors behavior for any kind of transactions.
   My mistake is that due to working with MithrilDB, I forgot to make a same changes to libmdbx.
