tcg: Assert fixed_reg is read-only

The only fixed_reg is cpu_env, and it should not be modified
during any TB.  Therefore code that tries to special-case moves
into a fixed_reg is dead.  Remove it.

tcg: Specify optional vector requirements with a list

Replace the single opcode in .opc with a null-terminated
array in .opt_opc.  We still require that all opcodes be
used with the same .vece.

Validate the contents of this list with CONFIG_DEBUG_TCG.
All tcg_gen_*_vec functions will check any list active
during .fniv expansion.  Swap the active list in and out
as we expand other opcodes, or take control away from the

sysbus device, but do not use CONFIG_PCI since they do not feature a PCI

Makefile: Fix inclusion of the config-devices.mak.d Kconfig dependencies

The Makefile tries to include device Kconfig dependencies via

 -include $(SUBDIR_DEVICES_MAK_DEP)

and thus expects files that match *-softmmu/config-devices.mak.d ...
however, the minikconf script currently generates files a la
"*-softmmu-config.devices.mak.d" instead, so the dependency files
simply got ignored so far. For example, after a "touch hw/arm/Kconfig",
the arm-softmmu/config-devices.mak file is currently not re-generated.
Fix it by putting the dependency files in the *-softmmu folders now.

Clean up header guards that don't match their file name

Header guard symbols should match their file name to make guard
collisions less likely.

Cleaned up with scripts/clean-header-guards.pl, followed by some
renaming of new guard symbols picked by the script to better ones.

[Rebase to master: update include/hw/net/ne2000-isa.h]

target/xtensa: Clean up core-isa.h header guards

scripts/clean-header-guards.pl warns these headers use reserved
identifier _XTENSA_CORE_CONFIGURATION_H as header guard symbol.  It
additionally warns the guard doesn't match the file name.

Reuse of the same guard symbol in multiple headers is okay as long as
they cannot be included together.

Since we can avoid guard symbol reuse easily, do so: use the guard
symbol scripts/clean-header-guards.pl picks, less the TARGET_ prefix.

linux-user: avoid treading on gprof's SIGPROF signals

know about. Given the gprof magic has also set up it's own handler we
would do well to avoid stomping on it as well.

linux-user: elf: Map empty PT_LOAD segments

Some PT_LOAD segments may be completely zeroed out and their p_filesize
is zero, in that case the loader should just allocate a page that's at
least p_memsz bytes large (plus eventual alignment padding).

Calling zero_bss does this job for us, all we have to do is make sure we
don't try to mmap a zero-length page.

docs: add Security chapter to the documentation

This new chapter in the QEMU documentation covers the security
requirements that QEMU is designed to meet and principles for securely
deploying QEMU.

It is just a starting point that can be extended in the future with more
information.

docs: add Secure Coding Practices to developer docs

At KVM Forum 2018 I gave a presentation on security in QEMU:
https://www.youtube.com/watch?v=YAdRf_hwxU8 (video)
https://vmsplice.net/~stefan/stefanha-kvm-forum-2018.pdf (slides)

This patch adds a guide to secure coding practices.  This document
covers things that developers should know about security in QEMU.  It is
just a starting point that we can expand on later.  I hope it will be
useful as a resource for new contributors and will save code reviewers
from explaining the same concepts many times.

aio-posix: ensure poll mode is left when aio_notify is called

With aio=thread, adaptive polling makes latency worse rather than
better, because it delays the execution of the ThreadPool's
completion bottom half.

event_notifier_poll() does run while polling, detecting that
a bottom half was scheduled by a worker thread, but because
ctx->notifier is explicitly ignored in run_poll_handlers_once(),
scheduling the BH does not count as making progress and
run_poll_handlers() keeps running.  Fix this by recomputing
the deadline after *timeout could have changed.

With this change, ThreadPool still cannot participate in polling
but at least it does not suffer from extra latency.

block/io.c: fix for the allocation failure

On a file system used by the customer, fallocate() returns an error
if the block is not properly aligned. So, bdrv_co_pwrite_zeroes()
fails. We can handle that case the same way as it is done for the
unsupported cases, namely, call to bdrv_driver_pwritev() that writes
zeroes to an image for the unaligned chunk of the block.
