PetscStack is on the stack now, removing the need to 'initialize' it so it can always be
used. The entire API has also been intern'ed since it is only internally used in select
instances.

Fix some spurious linter warnings and move certain headers to the private directory. Added
internal
PetscDisableStaticAnalyzerForExpressionUnderstandingThatThisIsDangerousAndBugprone() macro
to disable static analyzer for a single expression and a test for it. Improved the testing
logic slightly.

Style: replace "!rank" with "rank == 0"

In SF tutorial ex1 (src/vec/is/sf/tutorials/ex1.c), add parentheses around "rank == 0". This is relevant because ! binds more tightly than +, but == binds less
tightly, so the result of the computation would otherwise change.
