9fa4e21165 mdbx: fix assertion regression. 
Fixes https://github.com/ledgerwatch/erigon/issues/3874.

This was a minor regression after the c4a5325aafd3f03ce7520731b9da7253d7d178f0
that affects only debug builgs (with enabled assertions) and only when the added
code catch a incoherency of unified page/buffer cache.

d522069080 mdbx: fix rare SIGSEGV in cursor tracking code. 
The error was that the array of pointers in the transaction zeroed by the
value of env->me_numdbs and before txn->mt_numdbs was set to env->me_numdbs.
Thus, a cursor pointer(s) in the starting transaction could uninitialized if
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.

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

ef7b4289c0 mdbx: rework unaligned access. 
The three points:
 - disentangle C11-atomic fences/barriers and pure-functions (with `__attribute__((__pure__))`) to avoid compiler misoptimization;
 - fix hypotetic unaligned access to 64-bit dwords on ARM with `__ARM_FEATURE_UNALIGNED` defined;
 - reasonable paranoia that makes clarity for code readers.
