Fixes:
------

 - [Added workaround](https://github.com/erthink/libmdbx/issues/269) for a flaw of Linux 4.19 (at least) unified page/buffer cache.
 - [Fixed/Reworked](https://github.com/erthink/libmdbx/pull/270) move-assignment operators for "managed" classes of C++ API.
 - Fixed potential `SIGSEGV` while open DB with overrided non-default page size.
 - [Made](https://github.com/erthink/libmdbx/issues/267) `mdbx_env_open()` idempotence in failure cases.
 - Refined/Fixed pages reservation inside `mdbx_update_gc()` to avoid non-reclamation in a rare cases.
 - Fixed typo in a retained space calculation for the hsr-callback.

Minors:
-------

 - Reworked functions for meta-pages, split-off non-volatile.
 - Disentangled C11-atomic fences/barriers and pure-functions (with `__attribute__((__pure__))`) to avoid compiler misoptimization.
 - Fixed hypotetic unaligned access to 64-bit dwords on ARM with `__ARM_FEATURE_UNALIGNED` defined.
 - Reasonable paranoia that makes clarity for code readers.
 - Minor fixes Doxygen references, comments, descriptions, etc.
