In the aspeed_rtc device we store a difference between two time_t
values in an 'int'. This is not really correct when time_t could
be 64 bits. Enlarge the field to 'int64_t'.
This is a migration compatibility break for the aspeed boards.
While we are changing the vmstate, remove the accidental
duplicate of the offset field.

In the twl92230 device, use int64_t for the two state fields
sec_offset and alm_sec, because we set these to values that
are either time_t or differences between two time_t values.
These fields aren't saved in vmstate anywhere, so we can
safely widen them.

In the m48t59 device we almost always use 64-bit arithmetic when
dealing with time_t deltas. The one exception is in set_alarm(),
which currently uses a plain 'int' to hold the difference between two
time_t values. Switch to int64_t instead to avoid any possible
overflow issues.

We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.

The 'hwaddr' type is defined in "exec/hwaddr.h" as:
hwaddr is the type of a physical address
(its size can be different from 'target_ulong').
All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx:
$ fgrep define include/exec/hwaddr.h
#define HWADDR_H
#define HWADDR_BITS 64
#define HWADDR_MAX UINT64_MAX
#define TARGET_FMT_plx "%016" PRIx64
^^^^^^
#define HWADDR_PRId PRId64
#define HWADDR_PRIi PRIi64
#define HWADDR_PRIo PRIo64
#define HWADDR_PRIu PRIu64
#define HWADDR_PRIx PRIx64
#define HWADDR_PRIX PRIX64
Since hwaddr's size can be *different* from target_ulong, it is
very confusing to read one of its format using the 'TARGET_FMT_'
prefix, normally used for the target_long / target_ulong types:
$ fgrep TARGET_FMT_ include/exec/cpu-defs.h
#define TARGET_FMT_lx "%08x"
#define TARGET_FMT_ld "%d"
#define TARGET_FMT_lu "%u"
#define TARGET_FMT_lx "%016" PRIx64
#define TARGET_FMT_ld "%" PRId64
#define TARGET_FMT_lu "%" PRIu64
Apparently this format was missed during commit a8170e5e97
("Rename target_phys_addr_t to hwaddr"), so complete it by
doing a bulk-rename with:
$ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx)

The only reason for this code being target dependent was the IRQ-counting
related code in rtc_policy_slew_deliver_irq(). Since these functions have
been moved into a new, separate file (kvm_irqcount.c) which is now always
compiled and linked if necessary, we can get rid of the #ifdef TARGET_I386
switches in mc146818rtc.c and declare it in the softmmu_ss instead of
specific_ss, so that the code only gets compiled once for all targets.

These IRQ counting functions will soon be required in binaries that
do not include the APIC code, too, so let's extract them into a
separate file that can be linked independently of the APIC code.
While we're at it, change the apic_* prefix into kvm_* since the
functions are used from the i8259 PIC (i.e. not the APIC), too.

Add a new property "big-endian" to allow configuring the RTC as either
little or big endian, the default is little endian.
Currently overriding the default to big endian is only used by the m68k
virt platform. New platforms should prefer to use little endian and not
set this.
