Add a flag core.redraw to force redraw when rescan is done.
Inhibit recursion when files_limit is reached.
Still doesn't work correctly for files limited directories.
In theory the dmon based directory monitoring is enough to ensure that
the list of project files is always correct. In reality some events
may be missing and the project files list may get disaligned with the
real list of files.
To avoid the problem we add an additional rescan to be done later in a
thread on any project subdirectory affected by an event of directory of
file change.
In the rescan found the same files already present the thread terminates.
If a difference is found the files list is modified and a new rescan is
scheduled.
If the max number of files limit is achieved when the application
is starting the StatusView is not yet configured so we cannot
show the warning.
We show the warning in the function scanning the directory only if
the StatusView is up. On the other side, when the application starts
it will check if the initial project dir hit the max files limit and
show the warning if needed.
Introduce a new field in items generated by TreeView:each_item()
to point "dir" to the toplevel directory entry.
In this was we can simplify the code and know if the toplevel
directory is files limited.
Since the directory monitoring is now basically working we remove the
project scan thread periodically scanning the project directory.
Each project's directory is scanned only once at the beginning when
calling the function `core.add_project_directory` and is updated
incrementally when directory change events are treated.
The config variable `project_scan_rate` is removed as well as the
function `core.reschedule_project_scan`.
