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.
