While the DumpState begin and length variables directly mirror the API
variable names they are not very descriptive. So let's add a
"filter_area_" prefix and make has_filter a function checking length > 0.

get_start_block() returns the start address of the first memory block
or -1.
With the GuestPhysBlock iterator conversion we don't need to set the
start address and can therefore remove that code and the "start"
DumpState struct member. The only functionality left is the validation
of the start block so it only makes sense to re-name the function to
validate_start_block()

As HW virtualization requires specific support to handle breakpoints
lets push out special casing out of the core gdbstub code and into
AccelOpsClass. This will make it easier to add other accelerator
support and reduces some of the stub shenanigans.

This helps us construct strings elsewhere before echoing to the
monitor. It avoids having to jump through hoops like:
monitor_printf(mon, "%s", s->str);
It will be useful in following patches but for now convert all
existing plain "%s" printfs to use the _puts api.

Use the pc coming from db->pc_first rather than the TB.
Use the cached host_addr rather than re-computing for the

CHS-based disk utilities and operating systems may adjust the logical
geometry of a hard drive to cope with the expectations or limitations
of software using the ATA INITIALIZE_DEVICE_PARAMETERS command.
Prior to this patch, INITIALIZE_DEVICE_PARAMETERS was a nop that
always returned success, raising the possibility of data loss or
corruption if the CHS<->LBA translation redirected a write to the
wrong sector.
* hw/ide/core.c
ide_reset():
Reset the logical CHS geometry of the hard disk when the power-on
defaults feature is enabled.
cmd_specify():
a) New function implementing INITIALIZE_DEVICE_PARAMETERS.
b) Ignore calls for empty or ATAPI devices.
cmd_set_features():
Implement the power-on defaults enable and disable features.
struct ide_cmd_table:
Switch WIN_SPECIFY from cmd_nop() to cmd_specify().
ide_init_drive():
Set new fields 'drive_heads' and 'drive_sectors' based upon the
actual disk geometry.
* include/hw/ide/internal.h
struct IDEState:
a) Store the actual drive CHS values within the new fields
'drive_heads' and 'drive_sectors.'
b) Track whether a soft IDE reset should also reset the logical CHS
geometry of the hard disk within the new field 'reset_reverts'.
