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
* env: adds --ignore-signal
This commit implement #6164.

* test_env: add SIGSTOP to cspell workspace wordlist
* env: makes signal handling unix specific
* env: make ignore-signal function invocation unix specific
* test_env: make signal vector use slices ref instead of vec (linter)
* env: makes ignore-signal in options unix specific
* test_env: add unix specific import
* Fixed unwrap being called on dereferenced dangling symlink
* Added test
* Switched to regex matching in test
* Remove unnecessary mkdir call
* Modified documentation of the test and added assertion of the colors
* Fixed a typo
The test_cp and test_mv have xattr related tests. They should
be disabled on OpenBSD after commit 19d42c0339 disabled the
compare_xattrs function on OpenBSD.
Fixes#6348
