mdbx: release v0.12.1 (Positive Proxima)
The planned frontward release with new superior features on the day of 20 anniversary of [Positive Technologies](https://ptsecurty.com).

New:
----

 - The `Big Foot` feature which significantly reduces GC overhead for processing large lists of retired pages from huge transactions.
   Now _libmdbx_ avoid creating large chunks of PNLs (page number lists) which required a long sequences of free pages, aka large/overflow pages.
   Thus avoiding searching, allocating and storing such sequences inside GC.
 - Improved hot/online validation and checking of database pages both for more robustness and performance.
 - New solid and fast method to latch meta-pages called `Troika`.
   The minimum of memory barriers, reads, comparisons and conditional transitions are used.
 - New `MDBX_VALIDATION` environment options to extra validation of DB structure and pages content for carefully/safe handling damaged or untrusted DB.
 - Accelerated ×16/×8/×4 by AVX512/AVX2/SSE2/Neon implementations of search page sequences.
 - Added the `gcrtime_seconds16dot16` counter to the "Page Operation Statistics" that accumulates time spent for GC searching and reclaiming.
 - Copy-with-compactification now clears/zeroes unused gaps inside database pages.
 - The `C` and `C++` APIs has been extended and/or refined to simplify using `wchar_t` pathnames.
   On Windows the `mdbx_env_openW()`, `mdbx_env_get_pathW()`, `mdbx_env_copyW()`, `mdbx_env_open_for_recoveryW()` are available for now,
   but the `mdbx_env_get_path()` has been replaced in favor of `mdbx_env_get_pathW()`.
 - Added explicit error message for Buildroot's Microblaze toolchain maintainers.
 - Added `MDBX_MANAGE_BUILD_FLAGS` build options for CMake.
 - Speed-up internal `bsearch`/`lower_bound` implementation using branchless tactic, including workaround for CLANG x86 optimiser bug.
 - A lot internal refinement and micro-optimisations.
 - Internally counted volume of dirty pages (unused for now but for coming features).

Fixes:
------

 - Never use modern `__cxa_thread_atexit()` on Apple's OSes.
 - Don't check owner for finished transactions.
 - Fixed typo in `MDBX_EINVAL` which breaks MingGW builds with CLANG.

mdbx: release v0.11.10
The stable bugfix release.
It is planned that this will be the last release of the v0.11 branch.

New:
----

 - The C++ API has been refined to simplify support for `wchar_t` in path names.
 - Added explicit error message for Buildroot's Microblaze toolchain maintainers.

Fixes:
------

 - Never use modern `__cxa_thread_atexit()` on Apple's OSes.
 - Use `MultiByteToWideChar(CP_THREAD_ACP)` instead of `mbstowcs()`.
 - Don't check owner for finished transactions.
 - Fixed typo in `MDBX_EINVAL` which breaks MingGW builds with CLANG.

Minors:
-------

 - Fixed variable name typo.
 - Using `ldd` to check used dso.
 - Added `MDBX_WEAK_IMPORT_ATTRIBUTE` macro.
 - Use current transaction geometry for untouched parameters when `env_set_geometry()` called within a write transaction.
 - Minor clarified `iov_page()` failure case.

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.
