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).

Resolves https://github.com/erthink/libmdbx/issues/126

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.
