the following command is allowed at shell, we also make it allowed at virsh shell.

* tools/virsh.c (malloc, calloc, realloc, strdup): Enforce that
within this file, we use the safe vsh wrappers instead.
(cmdNodeListDevices, cmdSnapshotCreate, main): Fix violations of
this policy.

In origin code, double quote is only allowed at the begin or end
"complicated argument"
--some_opt="complicated string"  (we split this argument into 2 parts,
option and data, the data is "complicated string").

This patch makes it allow double quote at any position of
an argument:
complicated" argument"
complicated" "argument
--"some opt=complicated string"

This patch is also needed for the following patches,
the following patches will not split option argument into 2 parts,
so we have to allow double quote at any position of an argument.

We don't fail when we can't contact HAL so we shouldn't fail if we can't
contact D-Bus either.

* include/libvirt/libvirt.h.in: some of the function type description
  were broken so they could not be automatically documented
* src/util/event.c docs/apibuild.py: event.c exports one public API
  so it needs to be scanned too, avoid a few warnings

Make use of the existing <filesystem> element to support plan9fs
filesystem passthrough in the QEMU driver

    <filesystem type='mount'>
      <source dir='/export/to/guest'/>
      <target dir='/import/from/host'/>
    </filesystem>

NB, the target is not actually a directory, it is merely a arbitrary
string tag that is exported to the guest as a hint for where to mount
it.

* docs/Makefile.am: Add todo.pl and todo.cfg-example to EXTRA_DIST

Add proper documentation to the new VIR_DOMAIN_MEMORY_* macros in
libvirt.h.in to placate apibuild.py.

Mark args as unused in for libvirt_virDomain{Get,Set}MemoryParameters
in the Python bindings and add both to the libvirtMethods array.

Update remote_protocol-structs to placate make syntax-check.

Undo unintended modifications in vboxDomainGetInfo.

Update the function table of the VirtualBox and XenAPI drivers.

The command helps to control the memory/swap parameters for the system, for
eg. hard_limit (max memory the vm can use), soft_limit (limit during memory
contention), swap_hard_limit(max swap the vm can use)

since the replacement function virStrcpy is not available

Driver interface for getting memory parameters, eg. hard_limit,
soft_limit and swap_hard_limit.

Add support in the lxc driver for various memory controllable parameters

libvirt-lxc now configures the hardlimit, softlimit and swaplimit, if
specified in the domain xml file or picks up the defaults.

QEmu startup will pick up the memory tunables specified in the domain
configuration file

Driver interface for getting memory parameters, eg. hard_limit,
soft_limit and swap_hard_limit based on cgroup support

Driver interface for setting memory hard_limit, soft_limit and swap
hard_limit based on cgroup support

Provides interfaces for setting/getting memory tunables like hard_limit,
soft_limit and swap_hard_limit

Adding parsing code for memory tunables in the domain xml file
also change the internal define structures used for domain memory
informations
Adds a new specific test

The patch adds xml entries to the domain.rng file.

v2:
+ Fix typo min_guarantee

Public api to set/get memory tunables supported by the hypervisors.

dv:
* some cleanups in libvirt.c
* adding extra checks in libvirt.c new entry points

v4:
* Move exporting public API to this patch
* Add unsigned int flags to the public api for future extensions

v3:
* Add domainGetMemoryParamters and NULL in all the driver interface

v2:
* Initialize domainSetMemoryParameters to NULL in all the driver
  interface structure.

This patch adds a structure virMemoryParameter, it contains the name of
the
parameter and the type of the parameter along with a union.

dv:
+ rename enums to VIR_DOMAIN_MEMORY_PARAM_*
+ remove some extraneous tabs

v4:
+ Add unsigned int flags to the public api for future extensions

v3:
+ Protoype for virDomainGetMemoryParameters and dummy python binding.

v2:
+ Includes dummy python bindings for the library to build cleanly.
+ Define string constants like "hard_limit", etc.
+ re-order this patch.

Some features provided by the recently added CPU models were mentioned
twice for each model. This was a result of automatic generation of the
XML from qemu's CPU configuration file without noticing this redundancy.

Commit 1fe2927a forgot to export a symbol.

* src/libvirt_private.syms (virHexToBin): Add.
* src/.gitignore: Ignore temporary file.

To enable the CPU XML from the capabilities to be pasted directly
into the guest XML with no editing, pick a sensible default for
match and feature policy. The CPU match will be exact and the
feature policy will be require. This should ensure safety for
migration and give DWIM semantics for users

* src/conf/cpu_conf.c: Default to exact match and require policy
* docs/formatdomain.html.in: Document new defaults

This adds a script to generate the todo item page from
bugzilla. This requires a valid username+password for
bugzilla, so it is intended that this only be run on
the libvirt.org website via cron. Normal usage will just
generate an empty stub page.

* docs/todo.pl: Script to extract todo items from bugzilla
* docs/todo.cfg-example: Example config file
* docs/sitemap.html.in: Add todo page
* docs/Makefile.am: Generation rules for todo items

According to API documentation virDomain{At,De}tachDevice calls are
supposed to only work on active guests for device hotplug. For anything
beyond that, their *Flags variants have to be used.

Despite the variant which was acked on libvirt mailing list
(https://www.redhat.com/archives/libvir-list/2010-January/msg00385.html)
commit ed9c14a7 (by Jim Fehlig)
introduced automagic behavior of these API calls for xen driver. Since
January, these calls always change persistent configuration of a guest
and if the guest is currently active, they also hot(un)plug the device.

That change didn't follow API documentation and also broke device
hot(un)plug for older xend implementations which do not support changing
persistent configuration of a guest and hot(un)plugging in one step.

This patch should not break anything for active guests. On the other
hand, changing inactive guests is not supported any more.

xenXMDomain*DeviceFlags() silently ignores requests to modify live
configuration of an active guest while still touching its persistent
configuration.

When a user calls to virDomain{Attach,Detach,Update}DeviceFlags() with
flags == VIR_DOMAIN_DEVICE_MODIFY_LIVE on an inactive guest running on
an old Xen hypervisor (such as RHEL-5) xend_internal driver reports:

    Xend version does not support modifying persistent config

which is pretty confusing since no-one requested to modify persistent
config.

to avoid long timeouts waiting for DNS servers

This patch adds another example to the nwfilter html page and provides 2 solutions for how to write a filter meeting the given requirements using newly added features.

I am adding a row with information about the newly supported state
attribute to each of the tables describing supported attributes of protocols.

Extend the nwfilter.rng schema to accept state attribute.

This patch adds a test case for testing the XML parser's and instantiator's
support of the state attribute. The other test case tests existing
capabilities. Both test cases will be used in TCK again.

In this patch I am extending the rule instantiator to create the state
match according to the state attribute in the XML. Only one iptables
rule in the incoming or outgoing direction will be created for a rule
in direction 'in' or 'out' respectively. A rule in direction 'inout' does
get iptables rules in both directions.

The patch below extends the XML parser and generator so that every l3 protocol
now can have a state attribute.

* .gnulib: Update to latest, for bootstrap fixes.
* bootstrap: Synchronize with upstream.
* bootstrap.conf: Add pkg-config pre-requisite.
* autogen.sh: Tweak wording message.
