e766df658c mdbx-backport: 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.

d5658c496f mdbx: fix mp_txnid check for spilled pages. 
This is OMG stupid bug.

Тем не менее, ошибка не была замечена по трём причинам:
- some TODOs should be resolved, like [this](faddc71eac/src/core.c (4014)) and some others;
- test cases should be extended to triggering the page spilling threshold;
- mdbx_env_set_option() should be provide to tunning such threshold(s) (https://github.com/erthink/libmdbx/issues/128).
