Есть основание полагать, что mremap() может возвращать MAP_FAILED, но НЕ
устанавливать errno в некоторых пограничных ситуациях. Например, когда
системных ресурсов не хватает на актуализацию/копирование/клонирование
состояния отображения на финальной стадии, в том числе из-за раскраски
исходного отображения разными флагами через madvise().
The stable bugfix release.
Fixes:
------
- Fixed static assertion failure on platforms where the `off_t` type is wider
than corresponding fields of `struct flock` used for file locking (backport).
Now _libmdbx_ will use `fcntl64(F_GETLK64/F_SETLK64/F_SETLKW64)` if available.
- Fixed assertion check inside `page_retire_ex()` (backport).
Minors:
-------
- Fixed `-Wint-to-pointer-cast` warnings while casting to `mdbx_tid_t` (backport).
- Removed needless `LockFileEx()` inside `mdbx_env_copy()` (backport).

The stable bugfix release.
It is planned that this will be the last release of the v0.11 branch.
Fixes:
------
- Fixed an extra check for `MDBX_APPENDDUP` inside `mdbx_cursor_put()` which could result in returning `MDBX_EKEYMISMATCH` for valid cases.
- Fixed an extra ensure/assertion check of `oldest_reader` inside `mdbx_txn_end()`.
- Fixed derived C++ builds by removing `MDBX_INTERNAL_FUNC` for `mdbx_w2mb()` and `mdbx_mb2w()`.

- 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.

New:
----
- Ability to customise `MDBX_LOCK_SUFFIX`, `MDBX_DATANAME`, `MDBX_LOCKNAME` just by predefine ones during build.
- Added to [`mdbx::env_managed`](https://libmdbx.dqdkfa.ru/group__cxx__api.html#classmdbx_1_1env__managed)'s methods a few overloads with `const char* pathname` parameter (C++ API).
Fixes:
------
- Fixed hang copy-with-compactification of a corrupted DB
or in case the volume of output pages is a multiple of `MDBX_ENVCOPY_WRITEBUF`.
- Fixed standalone non-CMake build on MacOS (`#include AvailabilityMacros.h>`).
- Fixed unexpected `MDBX_PAGE_FULL` error in rare cases with large database page sizes.
Minors:
-------
- Minor fixes Doxygen references, comments, descriptions, etc.
- Fixed copy&paste typo inside `meta_checktxnid()`.
- Minor fix `meta_checktxnid()` to avoid assertion in debug mode.
- Minor fix `mdbx_env_set_geometry()` to avoid returning `EINVAL` in particular rare cases.
- Minor refine/fix batch-get testcase for large page size.
- Added `--pagesize NN` option to long-stotastic test script.
- Updated Valgrind-suppressions file for modern GCC.
- Fixed `has no symbols` warning from Apple's ranlib.
