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

Fix various regression test portability in tests/bugs.

bug-1004744.t:
- Slower systems really requires an increased REBALANCE_TIMEOUT in include.rc

bug-1023974.t:
- use the -p option to mkdir before the path for portability sake.

bug-1051896.t and bug-847622.t:
- skip ACL test for NetBSD as it has no POSIX 1e ACL support.

bugs-1053579.t:
- Override the amount of secondary groups depending of the maximum
  the system supports.
- Specify seq(1) format to avoid having trailing .00
- Use more portable su -m USER -c COMMAND (also in bug-884597.t)
- NetBSD does not fail high GID with NFS

bug-1058663.c:
- Depending on architecture, NetBSD can have SIGSEGV instead of SIGBUS

bug-762989.t and bug-867253.t:
- For non Linux systems, skip tests on features that are Linux-specific

bug-765473.t;
- Fix a {1} that bash is supposed to expand in 1 but does not, replace by 1.
- Sync volume to make sure it imediatly knows a fd got bad

- json_verify do not use '/usr/bin' let bash evaluate the location
- TEST for test code compilation `bug-1051896.t`, `bug-1058663.t`,
  bug-905864.t
- run-tests.sh - better checks for installed packages

Building arequal-checksum on non Linux systems requires a few adjustments:
- use __builtin_alloca() on all platforms
- on systems without argp, get it from contrib/standalone-argp
  (this requires adding cflags support to the build_tester function)
- FTW_ACTIONRETVAL option to nftw(3) is GNU libc specific, work around
  if it does not exist.
- md5sum is Linux-specific. Use md5 -n on NetBSD and md5 -q on FreeBSD/Darwin
- Use 'cc' as synonymous for all compilers, it can behave as gcc/clang depending
  on which is default
- cleanup tabs/whitespaces

1. errno was being set after gf_log() in posix_{f}handle_pair, this
would cause errno to be overwritten.

2. dht would expect -1 for indication of failure in setxattr
callback (dht_err_cbk()). posix_{f}setxattr has been changed to set
op_ret as -1 instead of -op_errno.

3. dict_foreach() has been changed to return an error if the invoked
fn() returns < 0.
