scipopt/scip v921 on GitHub

Fixed bugs

apply same feasibility definition in PaPILO as in SCIP to avoid numerical inconsistencies
check variable cancellation in SCIPvarAddVlb() and SCIPvarAddVub() to avert wrong infeasibility
SCIPfreeReoptSolve() now also clears partial solutions
fixed bug in calculation of "fractionality score" for spatial branching candidates in cons_nonlinear
fixed bug with installing symmetry dialog in sub-SCIPs
added copy callbacks for presolvers dualagg and redvub, branching rules lookahead and cloud, primal heuristics dualval and repair, propagator nlobbt, and separators gauge and convexproj
respect maximal separation rounds setting by running remaining delayed separators in last round
replace terms consistently in applyFixings() of cons_linear to handle infinite aggregations

fix SCIP Optimization Suite build with -DSYM=(s)bliss and bliss being downloaded and built during configuration by cmake
fix use of a bliss cmake installation specified via BLISS_DIR if -DSYM=(s)bliss

the check/solchecker build can now use also GMP installations by Homebrew on macOS/arm64

the output precision for writing CIP/OPB files has been increased at several places for nonlinear constraints
the solchecker tool now also supports SCIP solutions without unknown or infinite values
generate an error if the same linear constraint is used by several indicator constraints
