The balloon option is not i386 only, so move it into the standard
options section.

Michael Ellerman a3adb7ad3b vl.c: In qemu -h output, only print options for the arch we are running as
Only print options in the help output that are accepted by our arch.
This is less confusing for users and also for other programs that
consume the help output.

The options affected are:

 -g and -prom-env only displayed on PPC or SPARC

 -win2k-hack, -rtc-td-hack, -no-fd-bootchk, -no-acpi, -no-hpet,
 -acpitable, -smbios only displayed on i386

 -semihosting only displayed on ARM, M68K or XTENSA

 -old-param only displayed on ARM

Michael Ellerman 77bd1119ba vl.c: Move option generation logic into a wrapper file
In vl.c and qemu-options.h we define macros and include qemu-options.def
in order to generate different content. Move the bulk of the def'ing and
undef'ing into a wrapper, this will make it cleaner when we add another
macro in the next patch.

AFAICS undefining GEN_DOCS services no purpose, but I've left it for now.

Stefan Weil 50ced5b3b1 configure: Improve Xen autodetection for hosts without Xen
With this patch, it only takes one test (instead of four)
to detect that there is no Xen support at all.

For most build hosts, this will reduce the time configure needs.
It will also reduce noisy output in config.log.

Build hosts with Xen now need up to five (instead of up to four)
tests. They get improved diagnostics when Xen support fails.

Michael Roth 885660bd48 network scripts: don't block SIGCHLD before forking
This patch fixes a bug where child processes of launch_script() can
misbehave due to SIGCHLD being blocked. In the case of `sudo`, this
causes a permanent hang.

Previously a SIGCHLD handler was added to reap fork_exec()'d zombie
processes by calling waitpid(-1, ...). This required other
fork()/waitpid() callers to temporarilly block SIGCHILD to avoid
having the final wait status being intercepted by the SIGCHLD
handler:

7c3370d4fe

Since then, the qemu_add_child_watch() interface was added to allow
registration of such processes and reap only from that specific set
of PIDs:

4d54ec7898

As a result, we can now avoid blocking SIGCHLD in launch_script(), so
drop that behavior.

Stefan Hajnoczi db3a5ed7e4 usb: fix usb_qdev_init() error handling again
Commit f462141f18 introduced clean up code
when usb_qdev_init() fails.  Unfortunately it calls .handle_destroy()
when .init() was never invoked or failed.  This can lead to crashes when
.handle_destroy() tries to clean up things that were never initialized.

This patch is careful to undo only those steps that completed along the
usb_qdev_init() code path.  It's not as pretty as the unified error
handling in f462141f18 but it's necessary.

Andreas Färber 56384e8b1e exec.c: Fix subpage memory access to RAM MemoryRegion
Commit 95c318f5e1 (Fix segfault in mmio
subpage handling code.) prevented a segfault by making all subpage
registrations over an existing memory page perform an unassigned access.
Symptoms were writes not taking effect and reads returning zero.

Very small page sizes are not currently supported either,
so subpage memory areas cannot fully be avoided.

Therefore change the previous fix to use a new IO_MEM_SUBPAGE_RAM
instead of IO_MEM_UNASSIGNED. Suggested by Avi.
