Get page size in device init.
Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

Callers must pass ELF machine, byte swapping and symbol LSB clearing
information to ELF loader. A.out loader needs page size information, pass
that too as a parameter.

Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw.

Adjust callers. Also use target_phys_addr_t instead of target_ulong for
addresses: loader addresses aren't virtual.

It's a combination of a cut/paste bug (16 where it should be 32) as well

pcm_ops.run_out now takes number of live samples (which will be always

audio_pcm_hw_get_live_out anyway with exception of fmod which used
audio_pcm_hw_get_live_out2 for no good reason.

With this patch applied ide drives (when attached to a pci adapter) can
be created via -device, like this:

  -drive if=none,id=mydisk,file=/path/to/disk.img
  -device ide-drive,drive=mydisk,bus=ide.0,unit=0

Note that creating a master on ide1 doesn't work that way.  That is a
side effect of qemu creating a cdrom automagically even if you don't
ask for it.

Now that labels must be unique, the chr devices can't be opened anymore
within the serial port code (in case they are not already opened in
vl.c), as they end up with the same label. Instead opened so
non-assigned one directly in vl.c, with a different label.

This make MIPS Malta board emulation working again.

Single-stepping branches on MIPS didn't work right, because the
generation of EXCP_DEBUG happened after the generation of the code to
exit the current TB.  That is, given the code:

    bne v0,v1,target
    nop
    ...
  target:
    addu v0,v0,v1
  1:

when you single-stepped through the NOP, execution wouldn't actually
halt until you reached the label `1'.

This patch corrects that and also changes single-stepping so that a
branch and its delay slot are executed as one instruction for the
purposes of single-stepping.  This behavior is comparable to what other
MIPS tools (e.g. MIPSsim with MDI) do.  GDB avoids placing breakpoints
in branch delay slots, so this change doesn't break anything on the GDB
side.
