AFSVolMonitor (vos status) does not properly initialize its output
buffers. This leaks information from volserver memory:
struct transDebugInfo
- up to 29 bytes in member lastProcName (30-'\0')
- 16 bytes in members readNext, tranmitNext, lastSendTime,
lastReceiveTime
Initialize the buffers. This must be done on a per-buffer basis inside
the loop, since realloc is used to expand the storage if needed,
and there is not a standard realloc API to zero the newly allocated storage.
