This is ostensibly to avoid the weirdness of len looking like it might
come from a guest and sometimes being used. While we are at it fix up
the error checking for the arm-linux-user implementation of the API
which got flagged up by Coverity (CID 1401700).

Commit 58ea30f514 "Clean up header guards that don't match their file
name" messed up contrib/elf2dmp/qemu_elf.h and
tests/migration/migration-test.h.
It missed target/cris/opcode-cris.h and
tests/uefi-test-tools/UefiTestToolsPkg/Include/Guid/BiosTablesTest.h
due to the scripts/clean-header-guards.pl bug fixed in the previous
commit.
Commit a8b991b52d "Clean up ill-advised or unusual header guards"
missed include/hw/xen/io/ring.h for the same reason.
Commit 3979fca4b6 "disas: Rename include/disas/bfd.h back to
include/disas/dis-asm.h" neglected to update the guard symbol for the
rename.
Commit a331c6d774 "semihosting: implement a semihosting console"
created include/hw/semihosting/console.h with an ill-advised guard
symbol.
Clean them up.

This provides two functions for handling console output that handle
the common backend behaviour for semihosting.
