Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.

* Name: nxtk_subwindowmove
|
|
*
|
|
* Description:
|
|
* Perform common clipping operations in preparatons for calling nx_move()
|
|
*
|
|
* Input Parameters:
|
|
* fwnd - The framed window within which the move is to be done.
|
|
* This must have been previously created by nxtk_openwindow().
|
|
* destrect - The loccation to receive the clipped rectangle relative
|
|
* to containing window
|
|
* destoffset - The location to received the clipped offset.
|
|
* srcrect - Describes the rectangular region relative to the client
|
|
* sub-window to move relative to the sub-window
|
|
* srcoffset - The offset to move the region
|
|
* bounds - The subwindow bounds in absolute screen coordinates.
|
|
*
|
|
* Returned Value:
|
|
* OK on success; ERROR on failure with errno set appropriately
|
|
*
