DOSBox-X 0.83.0

Description

DOSBox-X is a fork of the original DOSBox project (www.dosbox.com).

0.83.0

Added mt32.romdir dosbox.conf configuration option for users who store the MT32 ROMs elsewhere other than the current working directory.
Configuration GUI settings menu is now vertically divided to ensure that it fits on the screen even if the window is at minimum size.
PC-98 GDC status fixed to follow the explicit definition of one bit as hblank and the other as vsync instead of carrying over VGA port 3DAh mstyle logic of hblank/vblank vs vsync. This fixes the BPS logo scanline effects in PC-98 game 'frontier-universe-bps-neo-kobe-pc98-ia'
Added dosbox.conf option to select between two known behaviors in PC-98 mode regarding the PC speaker and the PIT timer. The default behavior follows the newer hardware, the alternate setting is for older games written against the PC-9801 behavior.
Added dosbox.conf option nocachedir which, when set, instructs MOUNT to automatically act as if -nocachedir were given.
Linux/X11 SDL1 builds fixed not to issue resize commands to the window to avoid fighting the window manager. This prevents "spastic resizing" under Gnome 3 in Centos 8.
Source tree now includes build script for Linux users who prefer Clang/LLVM over GCC.
