* mm5740 X pins are numbered starting from 1, also fix typo in pinout comment (Y10, not Y0)
* make more members protected/private as appropriate
* got rid of one more video start override in a clean way
- Get rid of the hardcoded FLOPPY_n tags as much as practical, mostly adding device finder arrays in their place
- Move remaining functions using FLOPPY_n down into appldriv and sonydriv (both of which may be eliminated once FDC emulation is modernized)
- Replace CLEAR_LINE and ASSERT_LINE with 0 and 1 (these were being inaccurately used to represent active-low control line states)
- more const
- explicitly raise exceptions instead of leaving this to log.fatal()
- correct a number of cppcheck findings.
- dead code removal
- clang lint corrections, e.g. include order

This fixes a case where:
* m_soundbuf_samples == processedsamples
* processedsamples > 0
* processedsamples * stream->channels() == m_soundbuf.size()
In this scenario, the std::memmove() would do nothing (moving zero
bytes), but the operator[] on the second parameter to std::memmove()
overflows the array. This can be benign in optimized builds (because
the third parameter to std::memmove() is 0), but on debugging builds
this can cause an assert.
Both compiling the core and the shaders with __float128 now work.
The support was added to be ready to deal with academic edge cases.
Performance drops to 10% of double - thus disabled by default.
* galaga: Implement accurate starfield based on reverse eng. 05xx
----------------------------------------------------------------
This commit implements an accurate starfield for Galaga and
Bosconian based on reverse engineering the Namco 05xx chip.
Documentation and notes have been added inline to the code
for the galaga video driver.
Changes in this commit:
1. Regenerates starfield colors based on LFSR state for every frame
2. Pixel accurate to Namco original 05xx
3. Restores one line horizontal starfield shift for every 256
vertical pixel shifts
4. Properly handles LFSR reset (_STARCLR)
5. Restores missing 4 stars from previous implementations
6. Fixes potential issue with the number of stars on screen at any
one time
7. Restores 4 pixel/line scrolling capability (not currently used
for any driver)
* galaga: inplement accurate starfield - change request 1
-------------------------------------------------------
1. Remove stdlib.h from src/mame/video/galaga.cpp
* galaga: inplement accurate starfield - change request 2
-------------------------------------------------------
1. Refactor starfield generator into stand-alone video
device
2. Simplify Bosconian and Galaga video drivers
3. Add in documentation about different LFSR form used
by Wolfgang Scherr and Jindřich Makovička.
