974ebd5d91 - Add checks against ROM patches space 
- Make sure to also load the floppy disk driver with Gossamer ROMs so
  that exfs feature can work too

b8b139faf2 - Share EmulatorData & KernelData struct definitions 
- Introduce new SheepShaver data area for alternate stacks, thunks, etc.
- Experimental asynchronous interrupts handling. This improves performance
  by 30% but some (rare) lockups may occur. To be debugged!

3851071ecd Try to handle XLM_IRQ_NEST atomically in emulated PPC views. Fix placement 
of fake SCSIGlobals (disabled for now). Switch back to mono core emulation
until things are debugged enough. Implement get_resource() et al.

cb1dd6dac5 - Integrate new NativeOp instructions to be used as trampolines to call 
native functions from ppc code.
- Little endian fixes in emul_op.cpp
- Add new 'gpch' 750 patch to workaround crash with MacOS 8.6
- Don't crash in Process Manager on reset/shutdown with MacOS 8.6
- We also have an experimental interrupt thread in emulation mode

9e7670c922 Import VOSF from Basilisk II for faster and more accurate video refresh. 
There may be some bugs left though. Rework sigsegv_handler() a little to
accomodate VOSF way of life.

d29a00c17f Don't call FE0A opcode in Shutdown Manager: handle better NewWorld ROMs.

- Move FC1E routine base to ROM_BASE + 0x36fb00
- Recognize iMacUpdate 1.1 ROM (nwrom v1.2.1)

def097803e - B2_TOPDIR: new macro specifying where Basilisk II directory can be found. 
Update "links" rule to take care of it and don't PREFIX with current path
  if B2_TOPDIR yields an absolute path.
  (Simply cosmetic so that I can have multiple SS work dirs, effortlessly ;-)

d1b8e62cc9 - Invert AC_CHECK_LIB for readline and termcap so that the test program 
for readline detection is actually linked against -ltermcap -lreadline.
  Also add other term libs and finally prefer ncurses over the rest.
