KSPHPDDM: deprecate KSPHPDDMPrecision in favor of PetscPrecision

CI: add mumps/scalapack to a __float128 job

Have KSPView() indicate when there is no convergence test.

TS: fix docs for TSFunctionDomainError

Fix the definition of PetscErrorCodeFn; this reverts API change in !8615

tests: update CLEANFILES, and fix a compile target

Change use of void (*)(void) and void (**)(void) in the PETSc API to PetscVoidFn * and PetscVoidFn ** or PetscErrorCodeFn * or PetscErrorCodeFn **

TSPSEUDO: update needs to be copied inside the loop

Use Vec API to compute xdot
Remove redundant computation of xdot in Jacobian

Run fprettify

Deprecate MPIU_BOOL which used to be for PETSc' enum Bool but now is just MPI_C_BOOL so no longer needs its own name

clang-format: update to v21 (and update CI)

Remove unnecessary braces around one-liners

SNESLinesearch: Minor improvements

- add missing configuration options in the documentation of the line searches (some of the available options were not listed), and consistently list their respective default values

- add proper convergence criteria for the secant method in the L2 line search based on ltol and atol (otherwise, the secant method is mostly running for the maximum number of iterations)

- fix a small bug in the CP line search, where steptol * lambda was used to check for convergence based on the change of lambda instead of the ltol parameter

- rename sneslinesearch->maxstep to sneslinesearch->maxlambda in the options database to be consistent with its purpose in the algorithms

- rename SNESLineSearchL2 to SNESLineSearchSecant to better represent its underlying approach
