Bug ID: 495214
Summary: A filename whose length equals NAME_MAX cannot be
moved to wastebin, because appending `.trashinfo`
causes the resulting filename to exceed that value

SUMMARY
-------
Filenames at the 255-character limit (as defined by `NAME_MAX` in
`file:///usr/src/linux-headers-2.6.38-10/include/linux/limits.h`) cannot be
moved to the wastebin by appending `.trashinfo`, because the resultant filename
exceeds `NAME_MAX`. Consequently, this situation needs to be specially handled
by Dolphin, by:
1. Solely providing the "Delete" option, which is unintuitive and dangerous UX.
2. Prompting the user to manually reduce the filename before it can be moved to
the wastebin. This shall be problematic for multiple filenames, because not
everyone knows how to use KRename.
3. Automatically reducing the filename, and storing the original name in a
sidecar file. This is the best option, because the user shouldn't be manually
interacting with `$HOME/.local/share/Trash/` outside of `trash:/` anyway.
STEPS TO REPRODUCE
------------------
1. Name a file
`!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!`.
2. Attempt to send that file to the wastebin via Dolphin's context menu entry.
OBSERVED RESULT
---------------
It fails, with a nondescript error. See the attached screenshots.
EXPECTED RESULT
---------------
As aforementioned.

ADDITIONAL INFORMATION
