* tests/init.sh: Arrange not to accept FreeBSD 8.1's /bin/sh, since
it fails this test: /bin/sh -c 'f(){ local s=$IFS; test -n "$s"; }; f'
* tests/init.cfg (sanitize_path_): Stop-gap measure to work around
a bug in FreeBSD 8.1's /bin/sh. We'll un-do this change once all
300+ tests use init.sh.
* tests/init.cfg (retry_delay_): Describe
the backoff method used.
* tests/ls/readdir-mountpoint-inode: Add a timeout
to the stat call to eliminate the chance of hangups.
* tests/mv/i-3: Change the timeout required to pass
from 1 second to a range of .1s - 3.1s.
* tests/rm/dangling-symlink: Likewise.
All tests currently pass on NFS on Linux kernel 2.6.22 at least,
but some fail on 2.6.9, so we exclude those here.
* tests/init.cfg (is_local_dir_): A new function
returning if the specified directory is on a local file system.
(require_local_dir_): A new function to skip tests
if the current directory is not on a local file system.
* tests/cp/existing-perm-race: Skip if non local.
* tests/cp/file-perm-race: Likewise.
* tests/cp/parent-perm: Likewise.
* tests/cp/parent-perm-race: Likewise.
* tests/cp/preserve-2: Likewise.
* tests/mv/part-symlink: Likewise.
* tests/du/basic: Use refactored function.
* tests/install/basic-1: Likewise.
* tests/mkdir/p-3: Likewise.
* tests/dd/skip-seek-past-dev: Likewise.
* tests/du/slink: Likewise. Remove redundant test
for NFS file system.
* tests/misc/join: s/local/locale/.
* tests/init.cfg: Introduce a retry_delay_() function to
repeatedly call a test function that requires a delay.
This delay can now be shorter for the common case on fast
systems, but will double until a configurable limit it reached
before failing on slower systems.
* tests/dd/reblock: Use retry_delay_.
* tests/misc/cat-buf: Likewise.
* tests/misc/stdbuf: Likewise.
* tests/tail-2/F-vs-rename: Likewise.
* tests/tail-2/flush-initial: Likewise.
* tests/tail-2/tail-n0f: Likewise.
* tests/tail-2/wait: Likewise.
* test/dd/misc: Comment that delay is needed to trigger failure.
From there, they will be used by both test-lib.sh (as we phase it out)
and the newer init.sh, to which all tests will migrate.
* tests/test-lib.sh: Move most functions from here, ...
* tests/init.cfg: ...to here. New file.
* tests/Makefile.am (EXTRA_DIST): Add init.cfg.
