linux: Use getdents64 on readdir64 compat implementation
It uses a similar strategy from the non-LFS getdents that also
uses getdents64 internally, by reserving some space on the allocated
internal DIR buffer to be used as a temporary buffer. The kernel
obtained dirent64 struct are then copied to the temporary buffe
for each readdir compat call.
It allows to remove __old_getdents64.
Checked on i686-linux-gnu.

Date: Mon Apr 13 18:09:20 2020 -0300
linux: Set internal DIR filepos as off64_t [BZ #23960, BZ #24050]
It allows to obtain the expected entry offset on telldir and set
it correctly on seekdir on platforms where long int is smaller
than off64_t.
On such cases telldir will mantain an internal list of offsets per
DIR object that maps a long int, the function return value, to a
off64_t, the directory entry offset. The seekdir will then obtained
the correct offset from the internal list and rewinddir resets
the list as well.
It also removes the overflow check on readdir and the returned value
will be truncated by the non-LFS off_t size. As Joseph has noted
in BZ #23960 comment #22, d_off is an opaque value and telldir/seekdir
works using the DIR filepos field.
Finally it removed the requirement to check for overflow values on
telldir (BZ #24050).
Checked on i686-linux-gnu and x86_64-linux-gnu.

linux: Use getdents64 on non-LFS readdir
It reserves some space on the allocated internal DIR buffer to be
used as a temporary buffer. The kernel obtained dirent64 struct
are then copied to the temporary buffer for each readdir call.
The overflow test is moved to once the dirent64 entry is copied
to the temporary buffer and a subsequent readdir will obtain the
next entry. The idea is to work on filesystem that does not have
the idea of sequential d_off (such as ext4).
Checked on x86_64-linux-gnu and i686-linux-gnu.
