Review Request: check if enough disk space available before even starting to copy each file

Review request for kdelibs.


this is simple fix for 243160. It gets free space info for the dst partition, then after each successful file copy it decreases an internally kept m_freeSpace value.

this will help us avoid situations when user copies a 4gb long file onto his disk, then finds out it has not enough space available.

i hope that i correctly understood kio copy job mechanism and done error reporting right.

TODO (from what was asked in the bug):
*checking for single file size limit on vfat.
*if the total size is larger than free space, warn user beforehand immediately
(right now it does the copying until it finds that the next file cannot be copied completely)
both these require new dialogs with user visible strings and are subject to be added after 4.8.

also as a bonus i changed m_overwriteList to be qset instead of qlist to make lookup operations faster.

This addresses bug 243160.


  kio/kio/copyjob.cpp eff7825 



files get copied fine. if i copy a bunch of files including one big file
(created with dd if=/dev/zero of=file.out bs=1MB count=300), then the copying process stops when it gets to this big file (i have small disk on my virtual machine, only 400 mb free)
