If arch-specific code generates a translation block of size 0,
tb_gen_code() may generate a spurious exception.
Fix s390x (patch 1) and ARM (patch 2) and add an assertion in order to
catch such situations early (patch 3).
v1: https://lists.nongnu.org/archive/html/qemu-devel/2021-04/msg02037.html
tb_gen_code() assumes that tb->size must never be zero, otherwise it
may produce spurious exceptions. For ARM this may happen when creating
a translation block for the commpage.
Fix by pretending that commpage translation blocks have at least one
instruction.

All the code related to gdb has been moved from translate_init.c.inc
file to the gdbstub.c file, where it makes more sense.
This new version puts the prototypes in internal.h, to not expose
them unnecessarily.

All the current slave handlers on the qemu side generate an 'int'
return value that's squashed down to a bool (!!ret) and stuffed into
a uint64_t (field of a union) to be returned.
Move the uint64_t type back up through the individual handlers so
that we can make o

This series adds support for acceleration of virtiofs via DAX
