wal: hold file lock while renaming WAL directory on non-Windows
...
Windows requires this lock to be released before the directory is
renamed. But on unix-like operating systems, releasing the lock and
trying to reacquire it immediately can be flaky if a process is forked
around the same time. The file descriptors are marked as close-on-exec
by the Go runtime, but there is a window between the fork and exec where
another process will be holding the lock.

wal: zero out wal tail past its first zero record
...
Whenever the WAL is opened for writes, it should write zeroes to its tail
starting from the first zero record. Otherwise, if there are entries past
the first zero record due to a torn write, any new writes that overlap the
old entries will lead to a garbage record on the tail and cause a CRC
mismatch.

wal: Export SegmentSizeBytes as a variable

In test situations, it's useful to create smaller than usual WAL files
to test rotation and to avoid the overhead of preallocation on old-style
filesystems that don't handle it efficiently. This commit changes
segmentSizeBytes to an exported variable so that tests can override it
from an init() function.
