We allow a seclabel to be specified in the <source> element
of a chardev:
<serial type='file'>
<source path='/tmp/serial.file'>
<seclabel model='dac' relabel='no'/>
</source>
</serial>
But we format it outside the source:
<serial type='file'>
<source path='/tmp/serial.file'/>
<target port='0'/>
<seclabel model='dac' relabel='no'/>
</serial>
Move the formatting inside the source to fix this to make the
seclabel persistent across XML format->parse.
Introduced by commit f8b08d0 'Add <seclabel> to character devices.'
The DAC driver ignores the relabel='no' attribute in chardev config
<serial type='file'>
<source path='/tmp/jim/test.file'>
<seclabel model='dac' relabel='no'/>
</source>
<target port='0'/>
</serial>
This patch avoids labeling chardevs when relabel='no' is specified.

Currently, the DAC security driver passes callback data as
void params[2];
params[0] = mgr;
params[1] = def;
Clean this up by defining a structure for passing the callback
data. Moreover, there's no need to pass the whole virDomainDef
in the callback as the only thing needed in the callbacks is
virSecurityLabelDefPtr.

For internal structs, we might as well be type-safe and let the
compiler help us with less typing required on our part (getting
rid of casts is always nice). In trying to use enums directly,
I noticed two problems in virstoragefile.h that can't be fixed
without more invasive refactoring: virStorageSource.format is
used as more of a union of multiple enums in storage volume
code (so it has to remain an int), and virStorageSourcePoolDef
refers to pooltype whose enum is declared in src/conf, but where
src/util can't pull in headers from src/conf.
* src/util/virstoragefile.h (virStorageNetHostDef)

int for fields of internal types.

When qemu driver is polling for migration to finish (in
qemuMigrationWaitForCompletion), it may happen that another job allowed
during migration is running and if it does not finish within 30 seconds,
migration would be cancelled because of that. However, we can just
ignore the timeout and let the waiting loop try again later.
If an event fired at the end of migration is ever implemented in QEMU,
we can just wait for the event instead of polling for migration status
and libvirt will behave consistently, i.e., migration won't be cancelled
in case another job started during migration takes long time to finish.

qemuDomainPCIConnectFlags -> virDomainPCIConnectFlags
Also, move the related definitions and macros.

If qemuDomainBlockResize() is passed a size not on a KiB boundary - that
is passed a size based in bytes (VIR_DOMAIN_BLOCK_RESIZE_BYTES), then
depending on the source format (qcow2 or qed), the value passed must
be on a sector (or 512 byte) boundary. Since other libvirt code quietly
adjusts the capacity values, then do so here as well.
Commit 9976c4b9a6 broke the output for VNC
displays as the port number is converted to VNC display number by
subtracting 5900. This yields port 0 for the first display and thus the
output would be skipped.

Our documentation generator is a bit messy, to say the least. For
instance, the description to return values of a function is
searched within C comment. Currently, all lines that start with
'returns' or 'Returns' are viewed as return value description.
However, there are some valid uses where the 'returns' word is in
the middle of a sentence describing function behavior not the
return value. And there are no places where 'returns' is used to
describe return values. For instance:
virDomainDetachDeviceFlags, virConnectNetworkEventRegisterAny and
virDomainGetDiskErrors. This leads to HTML documemtation being
generated incorrectly.
