a1853dca74 qga: guest-exec simple stdin/stdout/stderr redirection
Implemented with base64-encoded strings in qga json protocol.
Glib portable GIOChannel is used for data I/O.

Optinal stdin parameter of guest-exec command is now used as
stdin content for spawned subprocess.

If capture-output bool flag is specified, guest-exec redirects out/err
file descriptiors internally to pipes and collects subprocess
output.

Guest-exe-status is modified to return this collected data to requestor
in base64 encoding.

4005b4732e qga: handle possible SIGPIPE in guest-file-write
qemu-ga should not exit on guest-file-write to pipe without read end
but proper error code should be returned. The behavior of the
spawned process should be default thus SIGPIPE processing should be
reset to default after fork() but before exec().

d697e30cff qga: guest exec functionality
Guest-exec rewritten in platform-independent style with glib spawn.

Child process is spawn asynchronously and exit status can later
be picked up by guest-exec-status command.

stdin/stdout/stderr of the child now is redirected to /dev/null
Later we will add ability to specify stdin in guest-exec command
and to get collected stdout/stderr with guest-exec-status.

62c39b307b tests: add a local test for guest agent
Add some local guest agent tests, as it is better than nothing, only
when CONFIG_POSIX (using unix sockets).

With the QGA_TEST_SIDE_EFFECTING environment variable, it will include
tests with side effects, such as freezing/thawing the FS or changing the
time.

(a better test would involve a managed VM (or container), but it might
be better to leave that off to autotest/avocado)

f3a06403b8 qga: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).  Same Coccinelle semantic patch as in commit b45c03f.

fafcaf1d74 build: qemu-ga: add 'qemu-ga' build target for w32
Currently POSIX builds rely on 'qemu-ga' target to do qga-only
distributable build. On w32, as with most standalone binary targets,
we rely on 'qemu-ga.exe' target.

Unlike with POSIX, qemu-ga for w32 has a number of related targets
such as VSS DLL and MSI package. We can do the full distributable
qga-only build on w32 with:

  make qemu-ga.exe

or:

  make msi

To make that work, we tie VSS dependencies onto qemu-ga.exe.
However, in reality the DLL isn't part of the binary, so we use a
filter to pull them out of the LINK recipe, which attempts to link
against prereqs for binary targets. Additionally, it could be argued
that VSS is a separate distributable, and shouldn't be implied by
qemu-ga.exe binary target.

To avoid this, we can tie the VSS dependencies only to the 'msi'
target, but that would make it impossible to do a qga-only build of
the w32 distributable without building the 'msi' package, which was
supported in the past.

An alternative approach is to add a new target to build the whole
distributable. w32 allows us to use the same build target we use
on POSIX, 'qemu-ga', since the current binary-only target on w32
is 'qemu-ga.exe'.

To further simplify the build, we also make 'qemu-ga' build the MSI
package if the appropriate ./configure options are set, making the
full qga-only build the same on both POSIX and w32: `make qemu-ga`

dbb7405d8c xen-platform: Ensure xen is enabled when initializing
The xen-platform code crashes on reset if the xen backend is not
initialized, because it calls xc_hvm_set_mem_type(). Ensure xen-platform
won't be created without initializing the xen backend.

The assert can't be triggered by the user because the device is not
hotpluggable, and the only code creating it (at pc_xen_hvm_init())
already checks xen_enabled().

8c84b25d97 qemu-char: convert stdio backend to data-driven creation
The backend now always returns errors via the Error* argument.
This avoids a double error message.  Before:

    qemu-system-x86_64: -chardev stdio,id=base: cannot use stdio with -daemonize
    qemu-system-x86_64: -chardev stdio,id=base: Failed to create chardev

After:

    qemu-system-x86_64: -chardev stdio,id=base: cannot use stdio with -daemonize

5d98bf8f38 target-arm: Fix CPU breakpoint handling
A QEMU breakpoint match is not definitely an architectural breakpoint
match. If an exception is generated unconditionally during translation,
it is hardly possible to ignore it in the debug exception handler.

Generate a call to a helper to check CPU breakpoints and raise an
exception only if any breakpoint matches architecturally.

external snapshot sense (i.e. bs->backing_hd), instead of the file sense
(bs->file). Correct the comment to use the right term.
