Register v47.1.4

Release notes:

• Added MOI.SolverVersion to the JuMP / MOI interface. It reports the version
  of the Xpress library actually loaded at runtime (via
  XPRSgetversionnumbers), which may differ from the version the bindings were
  built against, as a major.minor.build string.
• Added MOI.ListOfConstraintTypesPresent to the JuMP / MOI interface. It
  reports each (F, S) constraint-type tuple currently present in the model
  exactly once.
• Added MOI.ObjectiveFunctionType to the JuMP / MOI interface. It reports the
  type of the objective function currently set (MOI.VariableIndex,
  MOI.ScalarAffineFunction, MOI.ScalarQuadraticFunction, or
  MOI.VectorOfVariables), defaulting to MOI.ScalarAffineFunction when no
  objective has been set.
• Fixed the low-level wrapper for deferred-reference (dref) output-array
  functions such as XPRSgetqrowqmatrixtriplets when called with
  pre-allocated arrays (or nothing). The generated code previously skipped
  the C call on that path, returning the untouched input arrays and a size of
  0; it now issues the call and returns the correct data and size.
• Hardened the generated bindings against a garbage-collection use-after-free
  that could corrupt the heap (observed as intermittent access violations on
  Windows). String output buffers are now kept alive with GC.@preserve
  across the unsafe_string(pointer(...)) conversion, and callbacks are rooted
  in the problem's callback list before being registered with the C library.
• Reported callback support accurately: MOI.supports now returns true only
  for MOI.UserCutCallback (the one implemented callback) and false for
  MOI.LazyConstraintCallback and MOI.HeuristicCallback, instead of a
  blanket true that made JuMP offer callbacks that then failed at runtime.
  The feature docs were corrected to match.
• Cleaned up the generated low-level wrapper following upstream review
  feedback: module globals are now const or concretely typed (avoiding the
  untyped-global performance penalty); Libdl/SparseArrays are brought in
  with import and referenced qualified; the broken default argument on
  Base.showerror was removed; and redundant global/export statements
  were dropped (all XPRS-prefixed symbols are exported by a single loop).
• Fixed the SparseMatrixCSC overload of XPRSaddcols, which passed a
  malformed map.nzval instead of the matrix's non-zero values.
