linux-user: Add guest memory layout to exception dump

When the emulation stops with a hard exception it's very useful for
debugging purposes to dump the current guest memory layout (for an
example see /proc/self/maps) beside the CPU registers.

The open_self_maps() function provides such a memory dump, but since
it's located in the syscall.c file, various changes (add #includes, make
this function externally visible, ...) are needed to be able to call it
from the existing EXCP_DUMP() macro.

This patch takes another approach by re-defining EXCP_DUMP() to call
target_exception_dump(), which is in syscall.c, consolidates the log
print functions and allows to add the call to dump the memory layout.

Beside a reduced code footprint, this approach keeps the changes across
the various callers minimal, and keeps EXCP_DUMP() highlighted as
important macro/function.

qom/cpu: Simplify how CPUClass:cpu_dump_state() prints

CPUClass method dump_statistics() takes an fprintf()-like callback and
a FILE * to pass to it. Most callers pass fprintf() and stderr.
log_cpu_state() passes fprintf() and qemu_log_file.
hmp_info_registers() passes monitor_fprintf() and the current monitor
cast to FILE *. monitor_fprintf() casts it right back, and is
otherwise identical to monitor_printf().

The callback gets passed around a lot, which is tiresome. The
type-punning around monitor_fprintf() is ugly.

Drop the callback, and call qemu_fprintf() instead. Also gets rid of
the type-punning, since qemu_fprintf() takes NULL instead of the
current monitor cast to FILE *.
