9f0ff865e8 mdbx: use C11 atomics if available instead of legacy memory barriers. 
This done better support architectures with a weak/relaxed memory consistency model (ARM, AARCH64, PPC, MIPS, RISC-V, etc).

a8ed534cd3 mdbx: avoid 4-byte aligned (i.e. unaligned) access to 64-bit integers. 
Historically, the page header provides 4-byte data alignment.
Therefore, unfortunately, the meta page data is also aligned on a 4-byte boundary, but contains 64-bit values.

This commit eliminates potentially unsafe access (SPARC, MIPS, etc) to these 64-bit values aligned on a 4-byte boundary.
Thus, a build with the `-fsanitize=undefined` now passes the tests both with CLANG 11 and GCC 10.
