Clean up unit tests in the `dd` crate to make them easier to
manage. This commit does a few things.
* move test cases that test the complete functionality of the `dd`
program from the `dd_unit_tests` module up to the
`tests/by-util/test_dd.rs` module so that they can take advantage of
the testing framework and common testing tools provided by uutils,
* move test cases that test internal functions of the `dd`
implementation into the `tests` module within `dd.rs` so that they
live closer to the code they are testing,
* replace test cases defined by macros with test cases defined by
plain old functions to make the test cases easier to read at a
glance.
* include io-blksize parameter
* format changes for including io-blksize

This change is needed to fix missing USAGE section for `od` in user docs.
With reference to this issue
https://github.com/uutils/coreutils/issues/2991, and missing USAGE
section from `od docs` at
https://uutils.github.io/coreutils-docs/user/utils/od.html, it was
found that the USAGE for od app was starts with an empty line and uudoc
only takes 1st line for using in USAGE section in docs.
This resulted in empty line in usage section for `od`
Add support for the `-x` command-line option to `split`. This option
causes `split` to produce filenames with hexadecimal suffixes instead
of the default alphabetic suffixes.
Add a `NumericHexadecimal` member to the `SuffixType` enum so that a
future commit can add support for hexadecimal filename suffixes to the
`split` program.
Refactor the code to use a `SuffixType` enumeration with two members,
`Alphabetic` and `NumericDecimal`, representing the two currently
supported ways of producing filename suffixes. This prepares the code
to more easily support other formats, like numeric hexadecimal.
Correct the accounting for partial records written by `dd` to the
output file. After this commit, if fewer than `obs` bytes are written,
then that is counted as a partial record. For example,
$ printf 'abc' | dd bs=2 status=noxfer > /dev/null
1+1 records in
1+1 records out
That is, one complete record and one partial record are read from the
input, one complete record and one partial record are written to the
output. Previously, `dd` reported two complete records and zero
partial records written to the output in this case.
Change the `filter_mount_list()` function so that it always produces
the same order of `MountInfo` objects. This change ultimately results
in `df` printing its table of filesystems in the same order on each
execution. Previously, the table was in an arbitrary order because the
`MountInfo` objects were read from a `HashMap`.
Fixes#3086.
