This patch adds a simple structure to contain commonly-requested file properties (named `struct fileops_file_data`, wondering whether that name should that change?)
Functions added:
-void printFileData(): debugging function, printing contents of a `struct fileops_file_data` thing; -int shfileops_delete_file() function to delete given file -- making sure to call the right functions for either a regular file or a directory -int shfileop_unmasked_setup() the extracted code common for move and copy calls -int shfileop_move_unmasked the specific code on moving unmasked -- this one does a lot of recursion on SHFileOperationW -int shfileop_copy_unmasked the specific code on copying unmasked -- this one does some recursion too
Further more, I seperated code of deleting, renaming, moving, and copying, and the overall result is that code becomes simpler - though a small amount of code is duplicated (mostly in move/copy operations, that's why I split the largest part of common code in a separate function)
When this patch is accepted I'll submit the rest (that is, the code using these functions)
