tail: return inotify resources where possible
Each user has a maximum number of inotify watches,
so handle the cases where we exhaust these resources.
* src/tail.c (tail_forever_inotify): Ensure we inotify_rm_watch()
the watch for an inode, when replacing with a new watch for a name.
Return all used inotify resources when reverting to polling.
Revert to polling upon first indication of inotify resource exhaustion.
Revert to polling on any inotify resource exhaustion.
Diagnose resource exhaustion correctly in all cases.
Avoid redundant reinsertion in the hash for unchanged watches
(where only attributes of the file are changed).
* tests/tail-2/retry.sh: Avoid false failure when reverting to polling.
* tests/tail-2/inotify-rotate.sh: Likewise.
* tests/tail-2/symlink.sh: Likewise.
* tests/tail-2/inotify-rotate-resources.sh: New test to check
that we're calling inotify_rm_watch() for replaced files.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug fix.
* THANKS.in: Thanks for reporting and problem identification.
