* The saver/loadr commands should consider region endianness for portability.
-cpu/gigatron: Capitalisation of hex values was inconsistent, change it to lowercase as that tends to be the MAME standard.
-machine/exorterm.cpp: Fixed inputs magically changing on reset when they shouldn't (there are still others that should be fixed).
-mpu4vid.cpp: Corrected some errors in game descriptions.
-Fixed a couple of editing errors.

* Work around appveyor not being able to update msys2
There has been a change to msys2 package maintainers, meaning that the
packages are now signed with a different key:
https://www.msys2.org/news/#2020-06-29-new-packagers
Import the new keys manually until appveyor image is updated with a new
msys2-keyring package
* Explicitly kill msys2 before the second pacman call
* Example: PARAM(Solver.Solver_0.METHOD, "GMRES")
* Will use the GMRES solver instead of the default MAT_CR solver.
* Same applies to all Solver parameters.
* Please use with care. If you change your netlist (e.g. using
frontiers) the allocation of nets to solvers and the number of solvers
may change. Thus this type of tweaking should only be used after the
netlist completely works.
* The GMRES solver for larger matrices (>>100) can outperform Gaussian
elimination. Including it so it gets wider attention.
* As far as I know netlist is the only SPICE-like circuit simulation
providing a GMRES solver.
* All solver scheduling is now handled by nld_solver.
* Previously, for dynamic timestepping the sub solvers would be
responsible for their scheduling themselves.
- This prevented any attemps to use parallel execution of solvers.
* Now the route is free towards experiments to use parallel execution of
solvers.
* Uses ptimed_queue_linear in solver scheduling
* Improved netlist queue implementation (template now)
* Added const delegates.
* Added subsolver stats
* Removed dead code.
* pgm.cpp: fix timing of intro sequences in some games.
* pgm.cpp: Use generic gfx layout for foreground, Move VBlank IRQ into screen_vblank, Reduce duplicates, Add notes
* new NOT WORKING machines
