5f1b684719 mdbx: fix regression MDBX_KEYEXISTS during mdbx_commit_ex() and overwriting GC records. 
Fix regression related to https://github.com/erthink/libmdbx/issues/123 and https://github.com/erthink/libmdbx/issues/128.
Related to https://github.com/erthink/libmdbx/issues/131.

В lifo-режиме при фиксации транзакции, записи в GC могли быть перезаписаны (с утечкой страниц БД), либо могла возникать ошибка MDBX_KEYEXISTS, по следующему сценарию:
- В истории БД были две транзакции с огромным кол-вом retired pages, после которых в GC остались две соответствующие записи.
- В ходе очередной транзакции первая из огромных GC-записей попадает в переработку и образует огромный reclaimed list.
- При фиксации транзакции производится попытка разбить огромный reclaimed list на чанки размером в одну страницу. Для этого требуется много id для записей, которые в соответствии с lifo должны быть максимально близки к голове GC, т. е. получены путем переработки последних записей GC.
- В ходе переработки последних записей очередь доходит до второй огромной записи, при этом переработка прерывается, ибо иначе reclaimed list переполнится.
- Однако прерывание переработки внутри mdbx_update_gc() трактовалось как отсутствие записей в GC, поэтому список доступных просто добавлялись соответствующие id-шники.
- Если в списке доступных id-шников для помещения в GC были переработанные, то записи с id по всему списку удалялись - тогда вторая большая запись (и возможно предыдущие) удалялись, а содержащиеся в них номера страниц выпадали из оборота.
- Если же в списке доступных id-шников не было переработанных, то чистка не проводилась - тогда при последующая попытка помещения чанков reclaimed list в GC завершалась ошибкой MDBX_KEYEXISTS, которая и возвращалась из mdbx_commit_ex().

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.

- 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.

Resolves https://github.com/erthink/libmdbx/issues/123
but with TODO:
 - provide a user-configurable threshold instead of currently hard-coded default (MDBX_PNL_MAX/2).
