Some packages licensed under MPL-2.0 were incorrectly importing code
from packages licensed under BUSL-1.1.
Not all imports are fixed here as they will require additional work to
untangle them. To help track progress this commit adds a Semgrep rule
that detects incorrect BUSL-1.1 imports in MPL-2.0 packages.
This PR adds Merge() helper function for choosing which value of two pointers
to use during a larger merge operation.
If 'next' is not nil, use that value, otherwise use the 'previous' value.
This PR creates a pointer.Compare helper for comparing equality of
two pointers. Strictly only works with primitive types we know are
safe to derefence and compare using '=='.
This PR deprecates some functions in favor of generic alternatives.
The new functions are compatible only with Nomad v1.4+.
The old functions (nor their use) should not be removed until Nomad v1.6+.
