be220dc905 mdbx: release v0.9.3
Acknowledgements:
-----------------
 - [Mahlon E. Smith](http://www.martini.nu/) for [FreeBSD port of libmdbx](https://svnweb.freebsd.org/ports/head/databases/mdbx/).
 - [장세연](http://www.castis.com) for bug fixing and PR.
 - [Clément Renault](https://github.com/Kerollmops/heed) for [Heed](https://github.com/Kerollmops/heed) fully typed Rust wrapper.
 - [Alex Sharov](https://github.com/AskAlexSharov) for bug reporting.
 - [Noel Kuntze](https://github.com/Thermi) for bug reporting.

Removed options and features:
-----------------------------
 - Drop `MDBX_HUGE_TRANSACTIONS` build-option (now no longer required).

New features:
-------------
 - Package for FreeBSD is available now by Mahlon E. Smith.
 - New API functions to get/set various options (https://github.com/erthink/libmdbx/issues/128):
    - the maximum number of named databases for the environment;
    - the maximum number of threads/reader slots;
    - threshold (since the last unsteady commit) to force flush the data buffers to disk;
    - relative period (since the last unsteady commit) to force flush the data buffers to disk;
    - limit to grow a list of reclaimed/recycled page's numbers for finding a sequence of contiguous pages for large data items;
    - limit to grow a cache of dirty pages for reuse in the current transaction;
    - limit of a pre-allocated memory items for dirty pages;
    - limit of dirty pages for a write transaction;
    - initial allocation size for dirty pages list of a write transaction;
    - maximal part of the dirty pages may be spilled when necessary;
    - minimal part of the dirty pages should be spilled when necessary;
    - how much of the parent transaction dirty pages will be spilled while start each child transaction;
 - Unlimited/Dynamic size of retired and dirty page lists (https://github.com/erthink/libmdbx/issues/123).
 - Added `-p` option (purge subDB before loading) to `mdbx_load` tool.
 - Reworked spilling of large transaction and committing of nested transactions:
    - page spilling code reworked to avoid the flaws and bugs inherited from LMDB;
    - limit for number of dirty pages now is controllable at runtime;
    - a spilled pages, including overflow/large pages, now can be reused and refunded/compactified in nested transactions;
    - more effective refunding/compactification especially for the loosed page cache.
 - Added `MDBX_ENABLE_REFUND` and `MDBX_PNL_ASCENDING` internal/advanced build options.
 - Added `mdbx_default_pagesize()` function.
 - Better support architectures with a weak/relaxed memory consistency model (ARM, AARCH64, PPC, MIPS, RISC-V, etc) by means [C11 atomics](https://en.cppreference.com/w/c/atomic).
 - Speed up page number lists and dirty page lists (https://github.com/erthink/libmdbx/issues/132).
 - Added `LIBMDBX_NO_EXPORTS_LEGACY_API` build option.

Fixes:
------
 - Fixed missing cleanup (null assigned) in the C++ commit/abort (https://github.com/erthink/libmdbx/pull/143).
 - Fixed `mdbx_realloc()` for case of nullptr and `MDBX_AVOID_CRT=ON` for Windows.
 - Fixed the possibility to use invalid and renewed (closed & re-opened, dropped & re-created) DBI-handles (https://github.com/erthink/libmdbx/issues/146).
 - Fixed 4-byte aligned access to 64-bit integers, including access to the `bootid` meta-page's field (https://github.com/erthink/libmdbx/issues/153).
 - Fixed minor/potential memory leak during page flushing and unspilling.
 - Fixed handling states of cursors's and subDBs's for nested transactions.
 - Fixed page leak in extra rare case the list of retired pages changed during update GC on transaction commit.
 - Fixed assertions to avoid false-positive UB detection by CLANG/LLVM (https://github.com/erthink/libmdbx/issues/153).
 - Fixed `MDBX_TXN_FULL` and regressive `MDBX_KEYEXIST` during large transaction commit with `MDBX_LIFORECLAIM` (https://github.com/erthink/libmdbx/issues/123).
 - Fixed auto-recovery (`weak->steady` with the same boot-id) when Database size at last weak checkpoint is large than at last steady checkpoint.
 - Fixed operation on systems with unusual small/large page size, including PowerPC (https://github.com/erthink/libmdbx/issues/157).

TODO:
-----
 - Engage new terminology (https://github.com/erthink/libmdbx/issues/137).
 - Resolve few TODOs (https://github.com/erthink/libmdbx/issues/124, https://github.com/erthink/libmdbx/issues/127,    https://github.com/erthink/libmdbx/issues/115).
 - Finalize C++ API.
 - Packages for [ROSA Linux](https://www.rosalinux.ru/), [ALT Linux](https://www.altlinux.org/), Fedora/RHEL, Debian/Ubuntu.
