f574a5df05 Cleanups. Rewrite gen_bc() so that no push/pop could be inserted thus
causing crahes with some compilers. However, that's slower.

301d3a3192 STATS: Account for all interrupts, but still count native interrupts. It
turns out that for a regular bootup sequence to the Finder, less than 30%
interrupts triggered were in native mode.

Default EMUL_TIME_STATS to 0, end user probably doesn't want garbage to
be printed to his console.

a533a9c455 Enable DR emulator with OldWorld ROMs too. It turned out that translated
code was also trying to access Serial memory.

Note however that I noticed some rare crashes with the DR emulator.
Probably caused by nested runs from EmulOps? We'd really want a native
68k emulator too for Execute68k() things.

dd3a208906 Emulated lmw/stmw with unaligned EA. e.g. for BBEdit under MacOS 8.6.
This may be due to some switch mode that needs to save r13 and upwards.
The faultive code seems to explicitly add 0xee to r1, which causes it to
be unaligned for upcoming lmw/stmw.

b2bc1db356 Remove the "klipper" hack since it now (in KDE 3.2) checks for TIMESTAMP.
Besides, we are as smooth as before with last commits.

e291c6d065 Add fast X11 display locking routines based on spinlocks, or on pthreads
in the worst case. Optimize out GetScrap() case when we already own the
selection. i.e. make it smoother. Use our own XDisplay{Un,}Lock() routines.

ea33a5c8b0 Handle copy-paste between X11 and MacOS. X11 events handling code has to
be improved in copy mode (when we own the selection to service other clients).
Also note that older klipper has a tendency to request clipboard data
several times per second.
