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.

w32: QEMU applications with SDL are always GUI applications
Since commit
1d14ffa97eacd3cb722271eaf6f093038396eac4 (in 2005),
QEMU applications on W32 don't use the default SDL compiler flags:
Instead of a GUI application, a console application is created.
This has disadvantages (there is always an empty console window) and
no obvious reason, so this patch removes the strange flag modification.
The SDL GUI applications still can be run from a console window
and even send stdout and stderr to that console by setting environment
variable SDL_STDIO_REDIRECT=no.

qapi: Convert blockdev_snapshot_sync
Unfortunately, this conversion required an additional change.
In the old QMP command, the 'snapshot-file' argument is specified as
optional. The idea is to take the snapshot internally if 'snapshot-file'
is not passed. However, internal snapshots are not supported yet so
the command returns a MissingParamater error if 'snapshot-file' is not
passed. Which makes the argument actually required and will cause
compatibility breakage if we change that in the future.
To fix this the QAPI converted blockdev_snapshot_sync command makes the
'snapshot-file' argument required. Again, in practice it's actually required,
so this is not incompatible.
If we do implement internal snapshots someday, we'll need a new argument
for it.
Note that this discussion doesn't affect HMP.
