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:

7c3370d4fe3fa6cda8655f109e4659afc8ca4269

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:

4d54ec7898bd951007cb6122d5315584bd41d0c4

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

exec.c: Fix subpage memory access to RAM MemoryRegion

Commit 95c318f5e1f88d7e5bcc6deac17330fd4806a2d3 (Fix segfault in mmio
subpage handling code.) prevented a segfault by making all subpage

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

qdev: provide a path resolution (v2)

There are two types of supported paths--absolute paths and partial paths.

Absolute paths are derived from the root device and can follow child<> or
link<> properties.  Since they can follow link<> properties, they can be
arbitrarily long.  Absolute paths look like absolute filenames and are prefixed
with a leading slash.

Partial paths are look like relative filenames.  They do not begin with a
prefix.  The matching rules for partial paths are subtle but designed to make
specifying devices easy.  At each level of the composition tree, the partial
path is matched as an absolute path.  The first match is not returned.  At
least two matches are searched for.  A successful result is only returned if
only one match is founded.  If more than one match is found, a flag is returned
to indicate that the match was ambiguous.

At the end of the day, partial path support means that if you create a device
called 'ide0', you can just say 'ide0' as the path name and it will Just Work.
If we internally create a device called 'i440fx', you can just say 'i440fx' and
it will Just Work and long as you don't do anything silly.

A management tool should probably always use absolute paths since then they
don't have to deal with the possibility of ambiguity.

coroutine: switch per-thread free pool to a global pool

ucontext-based coroutines use a free pool to reduce allocations and

to improve locality.  However, as coroutines are usually allocated in

screwed up and we end allocating and freeing a coroutine for every I/O

tcg/arm: remove fixed map code buffer restriction

On ARM, don't map the code buffer at a fixed location, and fix up the
call/goto tcg routines to let it do long jumps.

Mapping the code buffer at a fixed address could sometimes result in it being
mapped over the top of the heap with pretty random results.

facilities to the new QMP dispatch/registry facilities, should the
QMP monitor ever have a need for such a thing.

Ideally, to avoid support/compatability issues in the future,
blacklisting guest agent functionality will be the exceptional
case, but we add the functionality here to handle guest administrators
