* Fix filerExcludeFileName to support directory names and path components
The original implementation only matched excludeFileName against
message.NewEntry.Name, which caused two issues:
1. Nil pointer panic on delete events (NewEntry is nil)
2. Files inside excluded directories were still backed up because
the parent directory name was not checked
This patch:
- Checks all path components in resp.Directory against the regexp
- Adds nil guard for message.NewEntry before accessing .Name
- Also checks message.OldEntry.Name for rename/delete events

* Add -filerExcludePathPattern flag and fix nil panic in filerExcludeFileName
Separate concerns between two exclude mechanisms:
- filerExcludeFileName: matches entry name only (leaf node)
- filerExcludePathPattern (NEW): matches any path component via regexp,
so files inside matched directories are also excluded
Also fixes nil pointer panic when filerExcludeFileName encounters
delete events where NewEntry is nil.

* Refactor exclude logic: per-side exclusion for rename events, reduce duplication
- Extract isEntryExcluded() to compute exclusion per old/new side,
so rename events crossing an exclude boundary are handled as
delete + create instead of being entirely skipped
- Extract compileExcludePattern() to deduplicate regexp compilation
- Replace strings.Split with allocation-free pathContainsMatch()
- Check message.NewParentPath (not just resp.Directory) for new side

* Move regexp compilation out of retry loop to fail fast on config errors
compileExcludePattern for -filerExcludeFileName and -filerExcludePathPattern
are configuration-time validations that will never succeed on retry.
Move them to runFilerBackup before the reconnect loop and use glog.Fatalf
on failure, so invalid patterns are caught immediately at startup instead
of being retried every 1.7 seconds indefinitely.

* Add wildcard matching helpers for path and filename exclusion
* Replace regexp exclude patterns with wildcard-based flags, deprecate -filerExcludeFileName
Add -filerExcludeFileNames and -filerExcludePathPatterns flags that accept
comma-separated wildcard patterns (*, ?) using the existing wildcard library.
Mark -filerExcludeFileName as deprecated but keep its regexp behavior.
