We have 3 different kinds of input:
* "algo (filename) = checksum"
example: `BLAKE2 (a) = bedfbb90d858c2d67b7ee8f7523be3d3b54004ef9e4f02f2ad79a1d05bfdfe49b81e3c92ebf99b504102b6bf003fa342587f5b3124c205f55204e8c4b4ce7d7c`
* "checksum filename"
example: `60b725f10c9c85c70d97880dfe8191b3 a`
* "checksum filename"
example: `60b725f10c9c85c70d97880dfe8191b3 a`
These algo/regexp are tricky as files can be called "a, " b", " ", or "*c".
We look at the first time to analyze the kind of input and reuse the same regexp then.
Summary of the change:
* Move the common code into checksum
* Create a structure HashAlgorithm to handle the algorithm (instead of the 3 variables)
* Use the same function for cksum & hashsum for --check (perform_checksum_validation)
* Use the same for function for the hash generation (digest_reader)
* Add unit tests
* Add integration tests
* Fix some incorrect tests
* hashsum: make tag conflicts with --text and --check
* hashsum: change the case in one of the gnu test
* build-gnu.sh: use symlink instead of copy
Plus: it won't cp new md5
* hashsum: also escape/unescape files with checks
Should fix tests/cksum/md5sum-bsd.sh
* improve the variable name

* hashsum: add --no-names option from official b3sum tool
The official b3sum tool has a --no-names option for only printing the
hashes, omitting the filenames. This is quite handy when used from
scripts because it spares the postprocessing with "cut" or "awk".
Since the installed b3sum symlink would also serve as a drop-in for the
official tool, the --no-names option is expected to exist for
compatibility.
Add a --no-names option not only for b3sum but for hashsum in general
(and maybe GNU coreutils will also feel inspired to add this option).

* hashsum: support --check for var. length outputs
Add the ability for `hashsum --check` to work with algorithms with
variable output length. Previously, the program would terminate with an
error due to constructing an invalid regular expression.
* fixup! hashsum: support --check for var. length outputs
