[BFW-7619]prusa link: Allow long filenames on item download from Prusa Link

[bkerler]

This solves issue #4476, which on download of previously long filename files will truncate the filename to short filenames via Prusa Link.

@bkerler Please verify if that is still an issue with FW 6.2.4, as I wrote in the related issue I was not able to reproduce it.

BTW the PR failed in the unit test.

[bkerler]

@3d-gussner sure, will try and report back.

@3d-gussner sure, will try and report back.

Thanks

@3d-gussner Yep, tested and bug is still there:

[bkerler]

Also confirmed that the bug also exists for latest 6.4.0 RC for Core One, not just MK4S

@bkerler Please verify if that is still an issue with FW 6.2.4, as I wrote in the related issue I was not able to reproduce it.

BTW the PR failed in the unit test.

The unit tests fails because the nhttp test uses sys/dirent.h instead of libsysbase/dirent.h which it should refer to. It was "quickfixed" in tests/gui/lazyfilelist/dirent.h but couldn't figure out anything similar for nhttp. It's less an issue of my PR but an issue with linkage/includes in the test itself.

[bkerler]

Instead of pointing to the updated dirent structure of libsysbase, I'm using the dirent_lfn instead which seems to do the trick.

@bkerler Thanks. I still have FW6.2.4+8909 on my MK4 and can't reproduce this.

This is so strange that you have the issue and I don't.

[bkerler]

@3d-gussner I think you also have this issue, but you are clicking on the wrong download field.

1. Select Projects.
2. Click on the filename. Do NOT click on the download icon.
3. Now click on the big "Download" button.
4. Filename will be 8+3 ext instead of long filename

If you directly click on the download icon and not on the filename and then download, the filename is of long format.

[3d-gussner]

@bkerler Thanks for the hint. Yes I can confirm, that the BIG DOWNLOAD button has the 8.3 filename.

The small download icon in Storage page works correctly.
