* tail: reduce CPU load for polling
This reduces the CPU load for polling drastically (from ~80% down to ~5%)
by removing/fixing several previous workarounds related to polling,
while still passing all related GNU test-suite checks.
* set Notify::PollWatcher delay to: sleep_sec/10 instead of
sleep_sec/100
* set recv_timeout to sleep_sec instead of sleep_sec/100
* remove the manual polling of watched files
Bugs:
* fix an issue with headers to consistently pass
"test_follow_name_retry_headers" and "gnu/tests/tail-2/overlay-headers.sh"
Code clean-up and refactor
* make fields of struct FileHandling private (and add getters/setters)
to ensure that the paths are absolute and match the paths returned by
Notify::Events
* replace calls to "crash!" with "return USimpleError"
* clean-up formatting
When `--backup` is supplied, `cp` will take a backup of *destination* before *source* is copied. When `--backup=simple` is supplied, it is possible for the backup path for *destination* to equal the path for *source*, destroying source before the copy is made. This change prevents this by returning an error instead.
This fixes https://github.com/uutils/coreutils/issues/3629
Update `dd` to only print a concise form of the number of bytes with
an SI prefix (like "1 MB" or "2 GB") if the number is at least
1000. Similarly, only print the concise form with an IEC prefix (like
"1 MiB" or "2 GiB") if the number is at least 1024. For example,
$ head -c 999 /dev/zero | dd > /dev/null
1+1 records in
1+1 records out
999 bytes copied, 0.0 s, 999.0 KB/s
$ head -c 1000 /dev/zero | dd > /dev/null
1+1 records in
1+1 records out
1000 bytes (1000 B) copied, 0.0 s, 1000.0 KB/s
$ head -c 1024 /dev/zero | dd > /dev/null
2+0 records in
2+0 records out
1024 bytes (1 KB, 1024 B) copied, 0.0 s, 1.0 MB/s
unnecessary trailing space was being added. because we were padding for alignment,
which is not required with -m

Several binaries have been added to `hashsum` that have never been part
of GNU Coreutils:
- `sha3*sum` (uutils/coreutils#869)
- `shake*sum` (uutils/coreutils#987)
- `b3sum` (uutils/coreutils#3108 and uutils/coreutils#3164)
In particular, the `--bits` option, and the `--no-names` option added in
uutils/coreutils#3361, are not valid for any GNU Coreutils `*sum` binary
(as of Coreutils 9.0).
This commit refactors the argument parsing so that `--bits` and
`--no-names` become invalid options for the binaries intended to match
the GNU Coreutils API, instead of being ignored options. It also
refactors the custom binary name handling to distinguish between
binaries intended to match the GNU Coreutils API, and binaries that
don't have that constraint.
Part of uutils/coreutils#2930.
