target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"

In commit 1bba0dc932 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.

The REG_PC constant used in opcode-cris.h can clash with a
similar define in system include files. In particular the
Ubuntu Lucid SPARC signal.h will define REG_PC, and since
qemu-common.h now includes signal.h this was causing compile
failures. Rename the constants to avoid this issue.
(NB that REG_SP is not actually used within QEMU.)

For i386, move wrappers for segment and FPU helpers from user-exec.c
to op_helper.c. Implement raise_exception_err_env() to handle dynamic
CPUState. Move the function declarations to cpu.h since they can be
used outside of op_helper.c context.

env_to_regs().
