Hi,
Btrfs self-test module assumed that both sectorsize and PAGE_SIZE are 4K.
Thus many self-tests fail on non-4K page size systems, like ppc64. This
patchset enables self-tests to be executed on non-4k page size systems.
This patchset enables us to easily add support for possible sectorsizes and
nodesizes (e.g. for future subpage-blocksize support).
This patchset also fixes the following bugs in self-tests:
1) Fix integer overflow when calculating bytes_per_bitmap
2) Fix infinite loop when searching for free space
3) Fix extent test_bitmaps fail on 64k sectorsize system
4) Fix extent buffer bitmap test fail on big-endian system
Also use macros instead of constants add add missing newline
when print strings in self-tests codes.

V1->V2:
1) use rb_next(&tmp->offset_index)/rb_prev(&tmp->offset_index) instead
of doing the info = tmp thing. As suggested by Josef Bacik.
2) Separate V1 patch "[PATCH 3/5] Btrfs: self-tests: Support non-4k
page size" to following patches in V2.
- [PATCH V2 3/8] Btrfs: self-tests: Support non-4k page size
- [PATCH V2 4/8] Btrfs: self-tests: Execute page straddling
test only when nodesize < PAGE_SIZE
- [PATCH V2 5/8] Btrfs: self-tests: Support testing all
possible sectorsizes and nodesizes
- [PATCH V2 6/8] Btrfs: self-tests: Use macros instead of
constants and add missing newline
As suggested by David Sterba that separate all change that are not
related to hardcoded 4096/sectorsize/PAGE_SIZE.
3) fix some coding style issue
