* i386: ignore float exceptions in debugger (nw)

* segas24.cpp: Read inputs through 315-5296

ibm5150: Prince of Persia v1.0 [ArcadeShadow]

ibm5170: Monkey Island 2: LeChuck's Revenge, Space Quest V: The Next Mutation [ArcadeShadow]

* Games added as GAME_NOT_WORKING:

Megatouch XL 6000 [R. Belmont, AeroCityMayor, Smitdogg, The Dumping Union]

* meritm.cpp: Minor corrections to Game name & rom name (nw)

* Made a few random methods 'const'

* Fix VS2015 build. (nw)

* More work on 9316. (nw)

* Refactored 74715 to one device layout. Removed subdevice. (nw)

* Netlist code refactoring:

- more use of c++ features

- some CRTP in pfmtlog

- demangled code for truthtables

- use more constexpr

- rewrite main loop

- use default constructors and assignment operators were applicable.

- optimized 7448 and 9316

All of this has decreased startup time by approx. 25% to 30%. Complex netlists like pong or kidniki are parsed, analyzed and constructed in around 15 ms. Run performance has increased by about 5%.

All in all not to bad. A game like pong uses a clock of 7 MHz (after division by 2). Thats 14 MHz clock invocations. Running at over 200%, 28 MHz. On a 3.9 GHz Machine about 140 cycles/clock change.

* naomi.cpp: converted remaining bad CHD v4 to good v5, track1 and track2 length was restored based on known now data patterns

* Fixed some regressions introduced in my recent refactoring related to software lists (#2217)

This fixes crashes invoked by the following command lines

mame nes zelda

mame gamate cubeup

These had two independent causes. The first crash was a consequence of open_image_file() doing something inappropriate required by implementations of get_default_card_software(). The second crash was a failure to access image options moved outside the core_options structure.

* P2 IO port should be optional. My apologies. (#2216)

Wireless 60 (Jungle Soft / Kids Station Toys Inc) P2 IO port should be optional. My apologies.

* sg1000a.cpp: correct year for sderby2. Thanks sjy96525 (nw)

* decocass.cpp: Correct missile colors for Highway Chase and Astro Fantasia

* otomedius: add on-screen version code displayed (nw)

* New games added as GAME_NOT_WORKING:

Police Trainer 2 [R. Belmont, gamerfan, Mr. CAST, Smitdogg, The Dumping Union]

* Fix palette-related regressions in Konami GX games (nw)

* Fixed gtrfrk6m from booting up due to an incorrect flash card memory size. 32MB works for gtrfrk5m as well. (#2214)

* New working machine added: Wireless 60 (Jungle Soft / Kids Station Toys Inc) (#2215)

* video/zeus2.cpp: fixed compile (nw)

* zeus2: Increase input fifo empty interrupt time and start to use address for quad selection. (nw)
