Leo Yuriev
45f159ddd3 mdbx: mdbx_cursor_put(MDBX_APPEND+MDBX_NOOVERWRITE) should return MDBX_KEYEXIST instead of MDBX_EKEYMISMATCH. 
When MDBX_APPEND is used the ordering of keys is important.
Therefore MDBX_EKEYMISMATCH should me returned when given key <= last.

On the other hand, if MDBX_NOOVERWRITE is also used
then the MDBX_KEYEXIST should be returned, but not MDBX_EKEYMISMATCH.

could be trigger assertion failure.

0f676db491 mdbx: add locking while open/close/drop dbi-handles (avoid dbi-related races). 
This avoid races and collisions between threads when opening,
closing and deleting DBI-handles.

unfortunately, this does not resolve collision in the case an one thread
closing the DBI-handle while the another thread performs transaction.
