There are around 300 regression tests, 250 being in tests/bugs. Running
partial set of tests/bugs is not easy because this is a flat directory
with almost all tests inside.
It would be valuable to make partial test/bugs easier, and allow the use
of mulitple build hosts for a single commit, each running a subset of
the tests for a quicker result.
Additional changes made:
- correct the include path for *.rc shell libraries and *.py utils
- make the testcases pass checkpatch
- arequal-checksum in afr/self-heal.t was never executed, now it is
- include.rc now complains loudly if it fails to find env.rc

This method deals with the case where swapping might gain a bigger overlap
for the xlator currently under consideration, but sacrifices even more from
the xlator we're swapping with. For example:
A = 0x00000000 - 0x44444443 (new 0x00000000 - 0x55555554)
B = 0x44444444 - 0x77777776 (new 0x55555555 - 0xaaaaaaa9)
C = 0x77777777 - 0xffffffff (new 0xaaaaaaaa - 0xffffffff)
Here, the new range for B has a bigger overlap with the old C than with the
old B (0x33333333 vs. 0x22222222 to be precise) so looking only at that
might lead us to swap. However, such a swap turns the new C's overlap from
0x55555556 (vs. old C) to *zero* (vs. old B). In other words, we've gained
0x11111111 for B but lost 0x55555556 for C, so it's a bad idea.
The new algorithm accounts for all effects of the swap, so it not only avoids
bad swaps but can make some good ones that would have been missed previously.
For example, if swapping a range X with a later range Y would not increase the
overlap for X we would previously have skipped it even if the swap would
increase Y's overlap without affecting X's. This is the normal case when we're
adding a new brick (which initially has zero overlap with any old range) so
finding more good swaps is probably even more important than avoiding bad ones.
Also, the logic in dht_overlap_calc was completely broken before, causing
integer overflows instead of providing correct values, so no matter what
higher-level algorithm was in place the GIGO effect would have resulted in
bad decisions.
