0ccec20409 mdbx: don't deem meta pages with zero txnid equal.
Устранение крайне маловероятного регресса после перехода на мета-тройку:
 - процесс А открыает БД и читает мета-траницы для формирования тройки;
 - процесс Б постоянно коммитит новые транзакции;
 - есть шанс что процесс А при чтении разных мета страниц попадет на момент их обновления более одного раза,
   это может привести к ложной ошибке коллизии мета-страниц,
   так как для обновляемых мета-страниц будет виден нулевой номер транзакции.

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

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.

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.

d7c06b1337 mdbx: partial fix for recursive SRW-lock with MDBX_NOTLS on Windows.
Here are some changes to avoid recursive acquisition of SRW-lock,
which is still in use:
 - Read transactions don't acquire the shared SRW-lock with `MDBX_NOTLS.
 - Memory-mapping of DB is always kept while DB opened,
   therefore following limitations are:
 - DB file can't be shrinked while it used,
   including auto-shrink due to auto-compactification with corresponding geometry settings.
 - The upper limit of DB size can't be changed while DB is used.
 - The DB can grow within the upper size limit defined while opening by a first process,
   but this does not work under Wine since there is no `NtExtendSection()` function.
