Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.
Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because
we know that failure can't happen.
Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling. I'm leaving
that for another day, because it involves making sure that error
values are properly checked by all callers.

This remove implicit rules + implicit variables.
Explicit rules like the generation of %.h and %.c from %.hx still works
as expected.
As an added bonus, now the output of make -d is readable.
As another added bonus, time spend on Makefiles is way smaller.
We run make -j3 in a fully compiled tree, and results are:
Before:
$ time make -j3
real 0m1.225s
user 0m1.660s
sys 0m0.253s
After:
$ time make -j3

Making pci device cleanup msix automatically makes pci.c depend on
msix.c, which is IMO messy. Since devices do msix_init it's easy and
natural for them to also do msix_uninit.

Also avoid dynamically sized array on stack - good for portability.

Now that net_client_init() has no users, kill it off and rename
net_client_init_from_opts().
There is no further need for the old code in net_client_parse() either.
We use qemu_opts_parse() 'firstname' facitity for that. Instead, move
the special handling of the 'vmchannel' type there.
Simplify the vl.c code into merely call net_client_parse() for each
-net command line option and then calling net_init_clients() later
to iterate over the options and create the clients.

Some parameters are not valid with fd=. Rather than having a separate
parameter description table for validating fd=, it's easir to just
check for those invalid parameters later.
Note, the need to possible lookup a file descriptor name from the
monitor is the reason why all these init functions are passed a Monitor
pointer.

We use a table of network types to look up the initialization function
and parameter descriptions in net_client_init().
For now, we use QemuOpts for the 'none' and 'nic' types. Subsequent
patches port the other types too and the special casing is removed.
We're not parsing the full -net option string here as the type has
been stripped from the string, so we do not use qemu_opts_parse()
'firstname' facility. This will also be rectified in subsequent
patches.
No functional changes are introduced by this patch.

Rather than overwriting a QemuOpt, just add a new one to the tail and
always do a reverse search for parameters to preserve the same
behaviour. We use this order so that foreach() iterates over the opts
in their original order.
This will allow us handle options where multiple values for the same
parameter is allowed - e.g. -net user,hostfwd=

Several qemu command line options have a parameter whose value affects
what other parameters are accepted for the option.
In these cases, we can have an empty description table in the
QemuOptsList and once the option has been parsed we can use a suitable
description table to validate the other parameters based on the value of
that parameter.
