b98895b8c7 mdbx: fix unaligned access to bootid on the meta-pages.
Assume this fixes https://github.com/erthink/libmdbx/issues/153

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.

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).

3fd079262c mdbx: fix extra-rare MDBX_KEY_EXIST during mdbx_commit().
The MDX_KEYEXISTS error could occur inside mdbx_update_gc() in the extremely rare case:

- no GC records was reclaimed before mdbx_txn_commit() called;

- there were few loose pages during the transaction;

- some reader prohibit reclaiming, therefore mdbx_page_alloc(MDBX_ALLOC_GC),
  which called for obtain present GC-record's Id, returns MDBX_NOTFOUND;

- immediately then the reader completes its transaction and unlocks reclaiming;

- mdbx_update_gc() decide that no reclaimable GC entries,
  i.e. no GC-entries with ID < find_oldest(),
  and it is safe to use find_oldest() - 1 to store loose page list;

- but find_oldest() actually returns new/larger ID than expected,
  So KEYEXISTS will returned if using this ID.

08faeda430 mdbx: refine mdbx_replace_ex().
We can skip update only when a data exactly the same,
but user's md_dcmp() may returns zero even data is NOT matches byte-to-byte.
So to skip update the cmp_len fast() should be used instead of md_dcmp().
