7604f99003 tail: Fix operation with +n argument
POSIX says

  Copying shall begin at the point in the file indicated by the -c
  number or -n number options.

  The origin for counting shall be 1; that is, -c +1 represents the
  first byte of the file, -c -1 the last.

  The origin for counting shall be 1; that is, -n +1 represents the
  first line of the file, -n -1 the last.

4859f4c825 ls: fix time handling by augmenting time resolution
ls was using (old) UNIX spec (struct stat).st_[acm]time.
It now uses POSIX (struct stat).(struct timespec st_[acm]tim) which
gives time resolution in seconds and nanoseconds.
If two files have the same time in seconds, we extend the comparision to
nanoseconds.

57d220b3dc ls: fix entities arrays handling in main()
Entities arrays in main() were arrays of pointer to entities and were
not compatible with entcmp().
They have been changed to being arrays of entities.
Thanks to Michael Forney <mforney@mforney.org> for having seen that.

674d1636f8 ls: Fix sorting of named entries
Previously, entcmp was being passed struct entry **, when it expected
struct entry *.

Many autoconf-generated configure scripts use `ls -t` to determine whether or
not the system clock is behaving correctly. If they are sorted in the wrong
order, it produces an error.

  checking whether build environment is sane... configure: error: newly created file is older than distributed files!
  Check your system clock

914991f5f6 Fix remaining endian-issue in od(1)
After setting up qemu and testing od(1) in a Big Endian environment,
I found out that the conditional in the printing function was not
right.
Instead, it's supposed to be way simpler. While at it, we don't need
HOST_BIG_ENDIAN any more. Just set big_endian properly in main()
and be done with it.

d03baf1697 Add -e and -E flags to od(1) and properly handle endianness
The -e and -E flags allow the user to override the host endianness
and force od(1) to handle input according to a little (-e) or big (-E)
endian environment.
The previous handling was broken as bitshifts alone are already
endian-independent.

092c95b66c Rewrite od(1)
Looking at the old code, it became clear that the desired
functionality with the t-flag could not be added unless the
underlying data-structures were reworked.
Thus the only way to be successful was to rewrite the whole thing.

od(1) allows giving arbitrarily many type-specs per call, both via
-t x1o2... and -t x1 -t o2 and intermixed.
This fortunately is easy to parse.
Now, to be flexible, it should not only support types of integral
length. Erroring out like this is inacceptable:

$ echo -n "shrek"| od -t u3
od: invalid type string ‘u3’;
this system doesn't provide a 3-byte integral type

Thus, this new od(1) just collects the bytes until shortly before
printing, when the numbers are written into a long long with the
proper offset.
The bytes per line are just the lcm of all given type-lengths and >= 16.
They are equal to 16 for all types that are possible to print using
the old od(1)'s.

Endianness is of course also supported, needs some testing though,
especially on Big Endian systems.

The logic is simple, it's just a pain in the ass to fill the

Some lines had to be commented out, as glibc/musl apparently

2013 corrigendum of POSIX 2008.

Also added a manpage and the necessary entries in README.

I also removed it from the TODO.

98e7e75ec6 Fix last offset output using skip in od(1)
Yeah, if the skipping is longer than the file itself, we need
to take the skip value, not the address.
