Subject: [PATCH 0/9] fix, rework and clean up for maple tree

I noticed that Liam R. Howlett's v2 patch set[1] has been merged. Merging v3
will have conflicts, so I included the extra parts of v3 relative to v2 into my
patch set. In this way, v3 can be ignored.

I made some changes to [4/9] from Liam R. Howlett, because it was not fully
fixed before, causing the test to fail.

Refactored mtree_alloc_range/rrange() to fix bugs and improve maintainability.
This makes the three functions mas_fill_gap(), mas_rev_alloc() and mas_alloc()
no longer used. But I did not delete them, because maple tree is still under
development. This refactoring is worth discussing. And I don't understand why
these three functions are needed because there are functions similar to them.
