Currently, 'info' will always report that mem = max mem. Make sure we
actually return the correct mem value.

Rather than numerous instances of:

emulator = vm->def->emulator;
if (!emulator)
    emulator = virDomainDefDefaultEmulator(conn, vm->def, driver->caps);
if (!emulator)
    return -1;

Set this value at XML parse time in the domain config, so we can depend on
it for all future emulator accesses. There were unchecked accesses in the
qemu driver that were tripping up on this if no emulator was specified in
the XML, see:

Parse the command line output a bit earlier so we have a better chance
of reporting the full error output on failure.

I hit this when QEMU would try to boot an invalid kernel (virtinst bug).

Currently we print the raw UUID which isn't very useful in ascii format.

By checking the pid every retry period, we can quickly determine if
the process crashed at startup, rather than make the user wait for
the entire timeout (3 seconds).

virExec will write out the pid of the daemonized process only. Use this
in the QEMU driver, rather than QEMU's pidfile, so we can catch errors we
might miss if the emulator bails early.

This ensures the user will actually see 'hook' function error output.

Wraps __virExec with the VIR_EXEC_DAEMON flag. Waits on the intermediate
process to ensure we don't end up with any zombies, and differentiates between
original process errors and intermediate process errors.

This change:

  Tue Mar  3 08:55:13 GMT 2009 Daniel P. Berrange <berrange@redhat.com>

       Don't try to detach & reset PCI devices while running test
       suite for XML-> ARGV conversion.
       * src/qemu_driver.c: Add qemuPrepareHostDevices() helper to
       detach and reset PCI devices.
       * src/qemu_conf.c: Don't detach & reset PCI devices while
       building the command line argv

accidentally did this:

-            if (hostdev->managed) {
+        if (!hostdev->managed) {

Which results in managed='yes' not causing the device to be
detached when the guest is starting.

Also fix up a couple issues where caps are accessed without locking
the driver structure.

It's logged via the logging system already. Prefix monitor debug output with vm
name.

built-in TODO list for each driver.  Also rip out the internal getURI method;
it is never used by any of the drivers, and was buggy to boot.
