Fix #28524: Push/Pull Assert when using Operator Panel to Alter Distance value

Some transform operators (like push/pull, shrink/fatten, to sphere and so)
were creating "value" as single scalar value. This used to confuse
RNA_float_get_array used in initTransform.

Use RNA_float_get_array for array values and RNA_float_get for scalar value
in transform initi function.

Fix for poly line grease pencil and surface drawing.

Fix BLI_smallhash for 0 and negative keys. Fixes some problems with edge snapping in knife tool.

remove -Wundef for code we don't maintain & generated code.

Fix for wrong offset of the input socket column in group node tree display.

Backward compatibility fix for SOCK_DYNAMICS flag on group sockets.

This is currently only needed for displaying the up/down buttons of group sockets. All regular group sockets should have this flag to indicate they are added by the user. More complex "group-type" trees may use non-dynamic sockets in the future for sockets that are not supposed to be manipulated.

fix link issues with MinGW - a substitute declaration(correctByteOrder) for itoln that was not present in MinGW was being used. Duplicated the declaration from <winsock2.h>(tried including but gave some errors) and added the appropriate link library, wsock32, according to MinGW documentation.

texture evaluation function (like we had in 2.4x api), requested by Lee.

eg:
red, green, blue, intensity = texture.evaluate(vec)

New grease pencil mode: poly line drawing

- It's like sketch mode for lines, but you're specifying line knots
by clicking on position you want to add next knot.
- View can be navigated between knots creation.
- Holding LMB down and sliding mouse will lead to new segment preview
so it can be created more accurate.

Additional change: fixed GP->Bezier conversion. Last point used to
be ignored in this operator.

Fix for #28517, group nodes losing all links from older files.

The reason was that group nodes tried to reconstruct sockets from the template lists, which are empty. Now the verification function checks if there are any sockets in the template lists, which are always empty for group nodes.

Grease pencil: non-blocking sketch sessions

- Implement own undo stack for grease pencil, so now there'll be no keymaps conflicts.
- Supported redo's during sketch session.
- Get rid of flag stored in Globals -- use undo stack to check if grease pencil session is active.
