svn commit: r271048 - head/lib/libc/gen

[John Baldwin]

Author: jhb

New Revision: 271048

Log:
  Always seek back to the beginning of a regular directory, even if the
  previous seek location was 0.  Without this, readdir() would see
  dd_loc of zero and call getdirentries() which would start reading
  entries at the current seek location of the directory ignoring the
  first batch of entries.  Also, rewinddir() should always seek so that
  it reads the directory from the beginning to get updated entries.
