e59e4904d3 Fix "ieee" FPU core on big endian and without long double > double support 
- Handle conversions to/from host double for m68k long doubles formats
- Make mathlib aware of sizeof(long double) == sizeof(double) arches
- Attempt to fix FSCALE implementation

c327eee41b * Basilisk II JIT integration, phase 2: 
- Add new FPU core architecture
- Clean fpu_x86_asm.h as it is no longer automatically generated

d3bda319a8 Use B2_mutex instead of pthread mutexes when ENABLE_EXCLUSIVE_SPCFLAGS is 
set. However, this is not used at the moment. Is there an advantage? People
may want to add arch-optimized SPCFLAGS_{SET,CLEAR}.

f5e58c95d6 - When X86_ASSEMBLY is set, aka when cpuopti is used, do call the 
instruction handler by hand and make sure to save %ebp too
- Really merge cpu core with uae-0.8.21:
  - Trace mode fixes (Bernd Roesch & Bernd Schmidt)
  - Reintegrate PTEST and PFLUSH instructions back as no-ops

20db0c7260 - 1-bit mode under X11 always uses default visual 
- fixed possible crash in driver_window dtor (image data would be freed twice,
  once by XDestroyImage() and once in driver_base dtor)

cb59a85240 - Experimental fixes for 64-bit addressing systems (e.g. Linux/ia64). The 
cpu emulation almost work correctly. FP emulation seems totaly boguous.

0cf3f32b7d video_x.cpp supports resolution switching in windowed mode: the available 
resolutions are 512x384, 640x480, 800x600, 1024x768 and 1280x1024 (the prefs
editor has to be updated to reflect this). The resolution selected in the
prefs editor is used as the default, but it can be changed in the Monitors
control panel. So far only tested with direct addressing.

- MOVE16 (Ay)+,(xxx).L
- MOVE16 (xxx).L,(Ay)+
- MOVE16 (Ay),(xxx).L
- MOVE16 (xxx).L,(Ay)

Fixes:
- MOVE16 (Ax)+,(Ay)+ where x == y: address register shall be incremented
  only once
- CINV, CPUSH: 'p' field matches correctly the instruction 'cache field'

- sys_unix.cpp: under Linux, partition sizes are read with BLKGETSIZE instead
  of llseek()
