Fixed PC speaker sound volume in PIT mode 0; A few CPU emulation clean-ups; Hard disk controller changing redone in a less messy way; Re-added the long-missing key send delay handling to the XT keyboard handler; Fixed a bug that was causing SLiRP not to work when compiled with MingW/GCC 7.3.0-2 or newer; Some serial mouse and port fixes; A lot of changes to printer emulation, mostly based on DOSBox-X; Printer PNG writer now uses statically linked libpng; Added support for the HxC MFM floppy image format and upped 86F format version to 2.12; Ported various things from PCem and some from VARCem; Added the S3 86c801/805 emulation (patch from TheCollector1995); Fixed and renamed the EGA monitor options; Better synchronized the 808x to the PIT and the CGA; Fixed the CGA wait state calculation; Cleaned up some things in mem.c; Fixed some things in the floppy emulation to make VisiOn get the correct errors from the copy protection disk; Fixed several renderer-related bugs, including the SDL2 renderer's failure to take screenshots; The Jenkins builds are now compiled with MingW/GCC 7.4.0-1 and include all the required DLL's.
