TextSearch: add option to set target to parent directory

Two usage scenarios:

* Wrong directory selected when invoking as Tracker add-on.
I often find myself having TextSearch invoked on selected child,
when I wanted it to open in parent context.
* Result was not found in target directory, so maybe the search
should be broader.

TextSearch: don't hard-code Pe editor

When double-clicking a result in TextSearch, it opens the file with
the preferred application for that file type. In case you search
through e.g. a HTML file, that would be most probably WebPositive,
which is not what you want normally.

TextSearch has the setting "Open files in Pe" which forces all files
to be opened in the Pe editor.

With this change, it will force the files to be opened in the
preferred app for text/x-source-code.

TextSearch: several small improvements

* Wakeup periodically search thread, cancelling should be
more responsive now...
* Show Lines setting is now saved too
* Fix a bug, current file is display again while searching.
* Always pass line number, if any, to invoked app.
Works with StyledEdit as with Pe.

Partially fix #13289.
Another change will add "open with" context menu and remove "Open with Pe".

TextSearch: way speeder by using xargs + grep

* Previously, each file was starting a shell to run grep
command on it. Very suboptimal performance, big overhead.
* Now a thread write each file path to xargs input,
while another start xargs, let it distribute files on
grep processes (one per cpu) and collect results asap.
* This bring results way faster than previously.
* Rename Escape Text setting into Regular Expression, as
name was more after shell workaround than after function.
* While it doesn't use a native text searching, by
reusing both grep and xargs power, it answer the main
issue with #9529.

Revert "TextSearch: use BString-based searching instead of Grep-based."

This reverts commit 1e9f5f5be4c8419c2085f51c78c9ac02ef13377b.
As per discussion on the ML.

TextSearch: use BString-based searching instead of Grep-based.

Huge performance improvement. Fixes #9529.

TextSearch: normalize copyright headers.

TextSearch: trim trailing whitespace.

TextSearch: don't save the 'show contents' option.

Also get rid of the redundant menu option.

Reverted part of r37829, because using B_COPY to copy selected entries in the hitslist makes it impossible to copy the search string in the text box. Oops.

Changed some menu strings and the shortcut to copy the selected text to the clipboard from B to C. Fixes #6404 and #6406.

* Added more tracing facilities (Function enter/exit printer)
* Decreased the node monitor activity timeout to 150 ms
* _StartNodeMonitoring() simply starts watching the root folder with the
B_WATCH_RECURSIVELY flag set. (Requires forthcomming changes to
BPathMonitor, but it was broken anyways.)
* _StopNodeMonitoring() returns early if node monitoring is inactive.
* When node monitoring is started after a search finished, it is done
asynchronous, since messing with the other controls results in modification
messages that otherwise stop node monitoring again. Now the message is
inserted last and works reliably.
* When receiving B_PATH_MONITOR messages, they are supposed to simply contain
a "path" field with the full path to the node that changed. That's not
currently the case with BPathMonitor, but I will commit that stuff next.
(Was broken before anyways.)

Finished implementing and enabled node monitoring on the folders and files
of the current search. If new files match the pattern, the appear in the
results, or are removed if they don't match anymore. The results also
adapt to changes in the files.
Basically, I added another iterator that is also used to track changes when
node monitor events arrive. Only those changed files are grepped again after
a timeout of .5 seconds when no new node monitor events pour in.

* Refactoring, added const specifiers to helper methods that don't modify the
object.
* Improved check that enforces search pattern history limit to also handle
the case when the limit is changed in the source.

Refactoring
* FileIterator is now a mostly abstract interface
* FolderIterator is the currently only implementation (there could be
MessageIterator for an even better separation, which would read the top
level search folders from the BMessage with the selected poses, but it
would mostly use the same code for traversing the subfolders anyways so I
left that for the time being.)
* The Grepper and FolderIterator now copy the current settings from the Model
at instantiation. Since they run in a separate thread and the Model may
actually be changed from the Window thread, I think this is just a cleaner
and more safe solution.
* Cleanup here and there.

Refactored a new class FileIterator from Grepper that will make adding
node monitoring easier. Also, FileIterator will be split to make the code
cleaner with regards to folder or selection mode.
