A bool 'report' has been introduced in various functions, which when set
to true will produce the error it is suppposed to produce, and when
false, will suppress the error. These functions are used in the next

Decompose vshCmddefOptParse into two helper functions, vshCmddefOptFill
and vshCmddefCheckInternals.

vshCmddefCheckInternals checks if the internal command definitions are
correct or not.

vshCmddefOptFill keeps track of the required options and mandatory
arguments through opts_required and opts_need_arg.

Before pushing this test, I changed the appropriate args file
to pet test-wrap-argv.pl, but forgot to change the xml file, so
update it accordingly.

A simple getopt-based argument parser is added for the /usr/sbin/bhyveload
command, loosely based on its argument parser.

The boot disk is guessed by iterating over all
disks and matching their sources. If any non-default arguments are found,
def->os.bootloaderArgs is set accordingly, and the bootloader is treated as a
custom bootloader.

Custom bootloader are supported by setting the def->os.bootloader and
def->os.bootloaderArgs accordingly

grub-bhyve is also treated as a custom bootloader. Since we don't get the
device map in the native format anyways, we can't reconstruct the complete
boot order. While it is possible to check what type the grub boot disk is by
checking if the --root argument is "cd" or "hd0,msdos1", and then just use the
first disk found, implementing the grub-bhyve argument parser as-is in the
grub-bhyve source would mean adding a dependency to argp or duplicating lots
of the code of argp. Therefore it's not really worth implementing that now.

A simpe getopt-based argument parser is added for the /usr/sbin/bhyve command,
loosely based on its argument parser, which reads the following from the bhyve
command line string:

* vm name
* number of vcpus
* memory size
* the time offset (UTC or localtime)
* features:
  * acpi
  * ioapic: While this flag is deprecated in FreeBSD r257423, keep checking for
    it for backwards compatibiility.
* the domain UUID; if not explicitely given, one will be generated.
* lpc devices: for now only the com1 and com2 are supported. It is required for
   these to be /dev/nmdm[\d+][AB], and the slave devices are automatically
   inferred from these to be the corresponding end of the virtual null-modem
   cable: /dev/nmdm<N>A <-> /dev/nmdm<N>B
* PCI devices:
  * Disks: these are numbered in the order they are found, for virtio and ahci
    disks separately. The destination is set to sdX or vdX with X='a'+index;
    therefore only 'z'-'a' disks are supported.
    Disks are considered to be block devices if the path
    starts with /dev, otherwise they are considered to be files.
  * Networks: only tap devices are supported. Since it isn't possible to tell
    the type of the network, VIR_DOMAIN_NET_TYPE_ETHERNET is assumed, since it
    is the most generic. If no mac is specified, one will be generated.

First, remove escaped newlines and split up the string into an argv-list for
the bhyve and loader commands, respectively. This is done by iterating over the
string splitting it by newlines, and then re-iterating over each line,
splitting it by spaces.

Since this code reuses part of the code of qemu_parse_command.c
(in bhyveCommandLine2argv), add the appropriate copyright notices.

Unconditionally use gnulib's getopt module. This is needed by the bhyve driver
to provide a reentrant interface for getopt.

Several gnulib headers rely on features.h being included by ctype.h to provide
__GNUC_PREREQ, but on systems without glibc, this is not provided. In these
cases __GNUC_PREREQ gets redefined to 0, which causes build errors from checks
in src/internal.h.
Therefore, define __GNUC_PREREQ as early as possible. config-post.h is probably
the first header that is included, before any other headers.

As the empty bitmap exists, we should also test it. This patch adds

Before the variable 'bits' was initialized with 0 (commit
3470cd86), the following bug was
possible.

A function call with an empty bitmap leads to undefined
behavior. Because if 'bitmap->map_len == 0' 'unusedBits' will be <= 0
and 'sz == 1'. So the non global and non static variable 'bits' would
have never been set. Consequently the check 'bits == 0' results in
undefined behavior.

This patch clarifies the current version of the function by handling the
empty bitmap explicitly. Also, for an empty bitmap there is obviously no
bit set so we can just return -1 (indicating no bit set) right away. The
explicit check for 'bits == 0' after the loop is unnecessary because we
only get to this point if no set bit was found.

Libxl is the last user and I don't have the toolchain prepared to
compile the libxl driver. Move it to the libxl driver to avoid having to
refactor the code.

Few arguments of the function are not necessary any more which leads to
some cleanups. The 'uri' argument had a stray ATTRIBUTE_UNUSED.

The impls are identical and I don't have a reasonable idea where to
extract it.

This also kills yet another use of virDomainLiveConfigHelperMethod.

Use a VIR_ prefix even when it's a local helper macro. It will be later

Currently, we have libvirt-client library which serves as a
collection point for all the libraries and client binaries we
have. Therefore we have couple of silly dependencies, for
instance libvirt-daemon depends on libvirt-client. Only because
the shared library is in the client package.
To solve this, new package libvirt-libs is introduced where all
the libraries are going to live. The client package is then set
to depend on this new package, just like the rest of packages
that suffer the same problem.

Same as with outputs; since the operations will be further divided into smaller
tasks, creating a filter will become a separate operation that will return

Right now, we define outputs one after another. However, the correct flow
should be to define a set of outputs as a whole unit. Therefore each output
should be first created, placed into an array/list and the list will be
defined. Output creation should be a separate operation, so an output will be
returned by a reference. From that perspective, it makes perfect sense to
only store pointers to actual outputs.

In this particular case, reset is meant as clearing the whole list of
outputs/filters, not resetting it to a predefined default setting. Looking at
it from that perspective, returning the number of records removed doesn't help
the caller in any way (not that any of the callers would actually check for
it). Well, callers could detect an error from the number of successfully
removed records, but the only thing that can fail in virLogReset is force
closing a file descriptor in which case the error isn't propagated back to
virLogReset anyway. Conclusion: there is no practical use for having a return
type of 'int' rather than 'void' in this case.

Due to the way the hardware works, KVM on ppc64 always requires
memory locking; however, that is not the case for non-KVM ppc64
guests, eg. ppc64 guests that are running on x86_64 with TCG.

Only require memory locking for ppc64 guests if they are using
KVM or, as it's the case for all architectures, they have host
devices assigned using VFIO.
