8f338032b9 rename qemuDomainDetachSCSIDiskDevice to qemuDomainDetachDiskDevice
The way to detach a USB disk is the same as that to detach a SCSI
disk. Rename this function and we can use it to detach a USB disk.

The reason is that we will try to lock some object in callback function, and we may call event API with locking the same object.
In the function virEventDispatchHandles(), we unlock eventLoop before calling callback function. I think we should
do the same thing in the function virEventCleanupTimeouts() and virEventCleanupHandles().

2ed6cc7bec Expose event loop implementation as a public API
Not all applications have an existing event loop they need
to integrate with. Forcing them to implement the libvirt
event loop integration APIs is an undue burden. This just
exposes our simple poll() based implementation for apps
to use. So instead of calling

   virEventRegister(....callbacks...)

The app would call

   virEventRegisterDefaultImpl()

And then have a thread somewhere calling

    static bool quit = false;
    ....
    while (!quit)
      virEventRunDefaultImpl()

82dfc6f38e qemu: Support vram for video of qxl type
For qemu names the primary vga as "qxl-vga":

  1) if vram is specified for 2nd qxl device:

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,vram_size=$SIZE,...

  2) if vram is not specified for 2nd qxl device, (use the default
     set by global):

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,...

For qemu names all qxl devices as "qxl":

  1) if vram is specified for 2nd qxl device:

    -vga qxl -global qxl.vram_size=$SIZE \
    -device qxl,id=video1,vram_size=$SIZE ...

  2) if vram is not specified for 2nd qxl device:

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,...

"-global" is the only way to define vram_size for the primary qxl
device, regardless of how qemu names it, (It's not good a good
way, as original idea of "-global" is to set a global default for
a driver property, but to specify vram for first qxl device, we
have to use it).

For other qxl devices, as they are represented by "-device", could
specify it directly and seperately for each, and it overrides the
default set by "-global" if specified.

v1 - v2:
  * modify "virDomainVideoDefaultRAM" so that it returns 16M as the
    default vram_size for qxl device.

  * vram_size * 1024 (qemu accepts bytes for vram_size).

  * apply default vram_size for qxl device for which vram_size is
    not specified.

  * modify "graphics-spice" tests (more sensiable vram_size)

  * Add an argument of virDomainDefPtr type for qemuBuildVideoDevStr,
    to use virDomainVideoDefaultRAM in qemuBuildVideoDevStr).

v2 - v3:
  * Modify default video memory size for qxl device from 16M to 24M

  * Update codes to be consistent with changes on qemu_capabilities.*

f8ac67909d qemu: avoid corruption of domain hashtable and misuse of freed domains
This was also found while investigating

   https://bugzilla.redhat.com/show_bug.cgi?id=670848

An EOF on a domain's monitor socket results in an event being queued
to handle the EOF. The handler calls qemuProcessHandleMonitorEOF. If
it is a transient domain, this leads to a call to
virDomainRemoveInactive, which removes the domain from the driver's
hashtable and unref's it. Nowhere in this code is the qemu driver lock
acquired.

However, all modifications to the driver's domain hashtable *must* be
done while holding the driver lock, otherwise the hashtable can become
corrupt, and (even more likely) another thread could call a different
hashtable function and acquire a pointer to the domain that is in the
process of being destroyed.

To prevent such a disaster, qemuProcessHandleMonitorEOF must get the
qemu driver lock *before* it gets the DomainObj's lock, and hold it
until it is finished with the DomainObj. This guarantees that nobody
else modifies the hashtable at the same time, and that anyone who had
already gotten the DomainObj from the hashtable prior to this call has
finished with it before we remove/destroy it.

e570ca1246 qemu: Add missing lock of virDomainObj before calling virDomainUnref
This was found while researching the root cause of:

https://bugzilla.redhat.com/show_bug.cgi?id=670848

virDomainUnref should only be called with the lock held for the
virDomainObj in question. However, when a transient qemu domain gets
EOF on its monitor socket, it queues an event which frees the monitor,
which unref's the virDomainObj without first locking it. If another
thread has already locked the virDomainObj, the modification of the
refcount could potentially be corrupted. In an extreme case, it could
also be potentially unlocked by virDomainObjFree, thus left open to
modification by anyone else who would have otherwise waited for the
lock (not to mention the fact that they would be accessing freed
data!).

The solution is to have qemuMonitorFree lock the domain object right
before unrefing it. Since the caller to qemuMonitorFree doesn't expect
this lock to be held, if the refcount doesn't go all the way to 0,
qemuMonitorFree must unlock it after the unref.

9677cd33ee util: Allow removing hash entries in virHashForEach
This fixes a possible crash of libvirtd during its startup. When qemu
driver reconnects to running domains, it iterates over all domain
objects in a hash. When reconnecting to an associated qemu monitor
fails and the domain is transient, it's immediately removed from the
hash. Despite the fact that it's explicitly forbidden to do so. If
libvirtd is lucky enough, virHashForEach will access random memory when
the callback finishes and the deamon will crash.

Since it's trivial to fix virHashForEach to allow removal of hash
entries while iterating through them, I went this way instead of fixing
qemuReconnectDomain callback (and possibly others) to avoid deleting the
entries.

fd21ecfd49 virExec: avoid uninitialized memory usage
valgrind warns:

==21079== Syscall param rt_sigaction(act->sa_mask) points to uninitialised byte(s)
==21079==    at 0x329840F63E: __libc_sigaction (sigaction.c:67)
==21079==    by 0x4E5A8E7: __virExec (util.c:661)

Regression introduced in commit ab07533e.  Technically, sa_mask
shouldn't affect operation if sa_flags selects sa_handler, and
sa_handler selects SIG_IGN, but better safe than sorry.

* src/util/util.c (__virExec): Supply missing sigemptyset.

4f2094a8a6 Allow 32-on-64 execution for LXC guests
Using the 'personality(2)' system call, we can make a container
on an x86_64 host appear to be i686. Likewise for most other
Linux 64bit arches.

* src/lxc/lxc_conf.c: Fill in 32bit capabilities for x86_64 hosts
* src/lxc/lxc_container.h, src/lxc/lxc_container.c: Add API to
  check if an arch has a 32bit alternative
* src/lxc/lxc_controller.c: Set the process personality when
  starting guest

35416720c2 Put <stdbool.h> into internal.h so it is available everywhere
Remove the <stdbool.h> header from all source files / headers
and just put it into internal.h

* src/internal.h: Add <stdbool.h>

9fc4b6a606 qemu: Switch over command line capabilities to virBitmap
This is done for two reasons:
- we are getting very close to 64 flags which is the maximum we can use
  with unsigned long long
- by using LL constants in enum we already violates C99 constraint that
  enum values have to fit into int

23d935bd97 qemu: Rename qemud\?CmdFlags to qemuCaps
The new name complies more with the fact that it contains a set of
qemuCapsFlags.

a96d08dc53 qemu: Use helper functions for handling cmd line capabilities
Three new functions (qemuCapsSet, qemuCapsClear, and qemuCapsGet) were
introduced replacing direct bit operations.

21642e82b1 qemu: Rename QEMUD_CMD_FLAG_* to QEMU_CAPS_*
The new names comply more with the fact that they are all members of
enum qemuCapsFlags.
