[fpc-pascal] File monitoring Linux

[cobines]

We have an implementation based on inotify in our project:

http://doublecmd.svn.sourceforge.net/viewvc/doublecmd/branches/0.5/src/platform/unix/inotify.pp
http://doublecmd.svn.sourceforge.net/viewvc/doublecmd/branches/0.5/src/platform/ufilesystemwatcher.pas

It has only been tested to work on directories.

However, as the docs say:

"Inotify monitoring of directories is not recursive: to monitor
subdirectories under a directory, additional watches must be created."

Our implementation is directed at handling few directories, so you
would need to optimize it to handle thousands of directories.
