Save sheet and symbol instance information to the clipboard on copy
Load sheet and symbol instance information from the clipboard on paste
and renumber page numbers after loading.
Correctly handle pasting in a multiple hierarchy by ensuring symbol and
sheet instances are updated for all instances of the destination sheet.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/8207
This breaks the following functions out to a general-purposed refdes utils
header:
* MODULE::GetReferencePrefix()
* kicad_string.h RefDesStringCompare()
This acheives:
* Slimming of MODULE interface
* Placement of refdes code in common rather than pcbnew
** Testing of this code in qa_common
* Tighter and smaller includes for code that only needed refdes functions
Note: there are failing tests commited (as expected failures). These
are the cause of lp:1813669 and will be fixed as a follow-up commit.
