af9b7b5605 mdbx: MAJOR rework page splitting (squashed). 
Basically, this (squashed) commit introduces:
 - An "auto-appending" feature upon insertion for both ascending and
   descending key sequences. As a result, the optimality of page filling
   increases significantly (more densely, less slackness) while
   inserting ordered sequences of keys,
 - A "splitting at middle" for more balanced page tree on average.

---

1. Using left/middle/right tactics for finding the split point of a page:
   - If a key is inserted close to an edge of page,
     then the page splits at that edge;
   - Otherwise a page splits at the middle,
     which leads to a more balanced tree on average;
   - So I expect a better behavior on average,
     but actually effects should be studied further practically.

2. New code for calculating the midpoint of a page split.

3. APPEND-flags no longer affect choosing the page split point.

4. Added left-side splitting by inserting a pure page with a new entry.

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().
