  * Use recently-introduced UML bit field extract instructions;
  * Don't follow arithmetic with redundant compare to zero if only zero flag is required;

- cirsa/neptunp2.cpp: Made perlacrb show the first error [Ivan Vangelista].
- cpu: Improved naming of TMS320 series DSPs [Vas Crabb]:
  * Name folders after families rather than the first family member emulated by MAME (yes, TMS320C1x and TMS320C2x are retrospective names);
  * Follow TI's convention of including the "C" in the names;
  * Don't try to jam all the disassembler source file names into 8.3;
  * The TMS32010, TMS320M10 and TMS320C10 are different things, but unfortunately MAME hasn't made a distinction between them so far. As far as I can tell, early DECTalk devices used TMS32010 or TMS320M10 chips, while the Atari and Toaplan games used TMS320C10 chips, but this should be verified.

- LUA: Ensuring that `entry:default_value()` returns the correct type (#14825) [npwoods]:
  * `entry:default_value()` was always returning string.  A consequence of this problem is that the following LUA commands would error;
  * ``` manager.options.entries['beam_dot_size']:value(manager.options.entries['beam_dot_size']:default_value()) manager.options.entries['frameskip']:value(manager.options.entries['frameskip']:default_value()) ```;
  * With this change, `default_value()` will return objects of the correct type.

- LUA: Fixing an issue setting float options (#14843) [npwoods]:
  * LUA only has a `number` type, and as such currently the handler for options of type `int` is going to intercept floating point numbers, even if they can't be cast to integers.  This can be reproduced with the following command:
  * ``` manager.options.entries['beam_dot_size']:value(2.5) ```
  * With this change, there is a single handler for LUA type `number` that takes a `float` and can set integer options provided that the `float` can be represented as an `int` losslessly.
- Revert "LUA:  Fixing an issue setting float options (#14843)" [Vas Crabb]:
  * This reverts commit 19ae7a99fc00b54809781f0171ec1c18d1e05e41;
  * The basic premise of the PR is wrong, and what it supposedly "fixes" works fine without the change.

- Revert "machine/spi_sdcard.cpp: Added configurable read/seek delays (#14763)" [Vas Crabb]:
  * This reverts commit 6607006b583841bf20244fe1acd1c8484ac56a35;
  * This didn't do what it purported to do, i.e. increase response delays. It actually decreased response delays in almost all cases, because it replaced the default SPI_DELAY_RESPONSE argument value with configured values that default to zero;
  * Since it's based on a misunderstanding and affects all systems using the device, I'm reverting it.  It simply doesn't make sense.
- Bump MAME 0.285 [Vas Crabb].
