Sometimes, we need to compare ASCII-only strings independently on the
current locales. Let's follow our cctype.h to implement such functions.

Let's use the same code for strtoul_or_err() and strtol_or_err() as we
already use for strtoxXX_or_err() functions. It resolves issue with
negative numbers.
This problem has been discovered by "./eject -x -1 -v" where -x is
based on strtoul_or_err(), but accepts negative number (-1).

Let's make it possible to use the function to normalize the string
between two buffers (from source to destination).

For example
./test_strutils --size '1.0000000000000000000000000000018000000000000000010M'
./test_strutils --size '1.18446744073709551615M'
ends with infinite loop due to frac_div variable overflow.

Old code:
./test_strutils --size 0.5MiB
0.5MiB : 512000 : 500K : 500 KiB
./test_strutils --size 0.50MiB
0.50MiB : 5120000 : 4.9M : 4.9 MiB
New code:
./test_strutils --size 0.5MiB
0.5MiB : 524288 : 512K : 512 KiB
./test_strutils --size 0.50MiB
0.50MiB : 524288 : 512K : 512 KiB
Note that the new implementation also does not use float points,
because we need to support PiB and so on... it seems good enough for
things like:
./test_strutils --size 7.13G
7.13G : 7656104581 : 7.1G : 7.1 GiB
./test_strutils --size 7.16G
7.16G : 7690675814 : 7.2G : 7.2 GiB
to avoid situation where cfdisk creates partition with completely
crazy numbers.

* don't cast from char to const char
* don't share endptr from strtoxxx() with rest of the code
as the end pointer is char, but code works with const chars

As discussed on the mailing list. We fix all places
where the non-working define STRTOXX_EXIT_CODE was used.

///aaa/bbb and /aaa/bbb/ are the same paths. This is important
especially with NFS where number of slashes are not the same in
the /proc/self/mountinfo and fstab or utab. The regular URI is
euler://tmp
but /proc contains
euler:/tmp

Currently the code supports /dev/name or PARTUUID= only. We also
need to support 'maj:min' and 'hexhex' notations.
