Cleanup: Nodes: Use consistent errors for nodes built without features

PyAPI: support retrieving the exception when running a string

- Optionally get the error as a single line.
- Support access the error as an allocated string.
- PyC_ExceptionBuffer_Simple was always printing to the `stdout` while
PyC_ExceptionBuffer didn't, now either print to the output.

Without this, callers are unable to do anything with the error string.

Fix T87400: GPencil change Select Alternate defaults

Now, the Unselect Ends is disabled by default.

DNA: support int8_t type in DNA structs

Differential Revision: https://developer.blender.org/D8908

CMake: fix error building with the version set to 300

When Blender's minor version was single digits, it wasn't properly
extracted. Resolve by adding zero padding.

Issue raised by @harley in D10954.

Fix compile error: Missing include paths

rB8d9fd0427dd6 added the `WITH_GMP` definition but did not append the
include paths.

GPencil: WIP geometry update flag

Tweaked InputToOutput scheduling.

No real difference in perfomance.

Cleanup: Pose library, move pose backup code into its own file

Move the pose backup & restore functionality into its own file, so that
the functions can be called from other places in Blender as well.

No functional changes.

Fix another crash

Compostior: Test for break to stop compositing.

GPencil: Bezier pen recalculate handles

Fix infinite loop bug

Merge branch 'master' into temp-compositor-scheduling

Motion Tracking: setting Keyframe A & B was not updating UI indicators

Entering the numbers in the keyframe field was not triggering a viewport
update, so the little green lines down in the cache area were only
change when the user e.g. changed the frame.

Now send appropriate notifiers.
