tail: reduce CPU load for polling (#3618) 
* 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

tail: add check to detect a closed file descriptor 
This is WIP or even WONT-FIX because there's a workaround in Rust's
stdlib which prevents us from detecting a closed FD.

tail: improve support for polling 
* Fix a timing related bug with polling (---disable-inotify) where some
Events weren't delivered fast enough by `Notify::PollWatcher` to pass all
of tests/tail-2/retry.sh and test_tail::{test_retry4, retry7}.

* uu_tail now reverts to polling automatically if inotify backend reports
too many open files (this mimics the behavior of GNU's tail).
