Save a cookie pointing to the very first entry in the DIR.dd_buf
cache buffer and use that to speed up seekdir(3) when rewinding
to that first entry.
No libc bump because DIR is an opaque struct.
When the optimization applies, which in particular it always does
for rewinddir(3) after reading less than about 500 entries,
seekdir(3) execution time drops from 100 to 0.05 milliseconds
on my i386 notebook. Other cases are not slowed down.
Based on an idea from and ok by guenther@.

1. avoid code duplication in rewinddir() by calling seekdir() directly
2. move __seekdir() into seekdir() and _telldir_unlocked() into telldir()
Both functions were called from nowhere else.
3. remove some unused #include directives and one unused function prototype

members to 64bit types. Assign new syscall numbers for (almost
all) the syscalls that involve the affected types, including anything
with time_t, timeval, itimerval, timespec, rusage, dirent, stat,
or kevent arguments. Add a d_off member to struct dirent and replace
getdirentries() with getdents(), thus immensely simplifying and
accelerating telldir/seekdir. Build perl with -DBIG_TIME.
Bump the major on every single base library: the compat bits included
here are only good enough to make the transition; the T32 compat
option will be burned as soon as we've reached the new world are
are happy with the snapshots for all architectures.
DANGER: ABI incompatibility. Updating to this kernel requires extra
work or you won't be able to login: install a snapshot instead.
Much assistance in fixing userland issues from deraadt@ and tedu@
and build assistance from todd@ and otto@

typedef regardless of __BSD_VISIBLE, and eliminate the dirfd() macro.

so it works correctly with large offsets (and matches other systems).
This requires adding a new getdirentries syscall, with the old one
renamed to ogetdirentries. All in-tree consumers of getdirentries()
have been updated. Bump libc and libpthread major numbers.
OK and with deraadt@

while still returning the correct index for seekdir(); telldir()
Tested by Fred Crowson and others; "put it in" deraadt@

- Fix semantics: seekdir(pos); telldir() shoud return pos. The code
that implements this will be made faster in a later commit.
- We loose documented behaviour (after closedir() the telldir()
positions are not valid anymore). This was never in Posix, and most
other systems have nothing like it.
Diff originally from Paul Thorn, rewritten by me using some FreeBSD
code. "slap it in" deraadt@
