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.

Fixes https://github.com/erthink/libmdbx/issues/272.
