680c92ae7e ESX: Fix memory leak in list handling functions.
If an error occurs between the allocation of an item and appending it
to the list, the item leaks. Free such orphaned items in error cases.

b79aaf91b8 ESX: Don't automatically follow redirects.
The default transport for the VI API is HTTPS. If the server redirects
from HTTPS to HTTP the driver would silently follow that redirection.
The user assumes to communicate with the server over a secure transport
but isn't.

This patch disables automatical redirection following. The driver reports
an error if the server tries to redirect.

* src/esx/esx_vi.c: refactor the call to curl_easy_perform() into a
  function and do error handling there, disable automatical redirection
  following for curl
* src/esx/esx_vi.h: change the type of responseCode to int

7c7681dd90 ESX: Change disk selection for datastore detection.
In order to register a new virtual machine the ESX driver needs to upload
a VMX file to a datastore. Try to put this file beside the main VMDK file
of the virtual machine. Change the disk selection for datastore detection
to choose the first file-based harddisk instead of just the first disk.
The first disk may be a CDROM disk and ISO images are normaly not located
in the virtual machine's directory.

4296cea2b2 Don't let parent of daemon exit until basic initialization is done
The daemonizing code lets the parent exit almost immediately. This
means that it may think it has successfully started even when
important failures occur like not being able to acquire the PID
file. It also means network sockets are not yet open.

To address this when daemonizing the parent passes an open pipe
file descriptor to the child. The child does its basic initialization
and then writes a status code to the pipe indicating either success,
or failure. This ensures that when daemonizing, the parent does not
exit until the pidfile is acquired & basic network sockets are open.

Initialization of the libvirt drivers is still done asynchronously
since this may take a very long time.

  file, pidfile & network socket init is completed

3505790b85 Allow for a driver specific private data blob in virDomainObjPtr
The virDomainObjPtr object stores state about a running domain.
This object is shared across all drivers so it is not appropriate
to include driver specific state here. This patch adds the ability
to request a blob of private data per domain object instance. The
driver must provide a allocator & deallocator for this purpose

THis patch abuses the virCapabilitiesPtr structure for storing the
allocator/deallocator callbacks, since it is already being abused
for other internal things relating to parsing. This should be moved
out into a separate object at some point.

* src/conf/capabilities.h: Add privateDataAllocFunc and
  privateDataFreeFunc fields
* src/conf/domain_conf.c: Invoke the driver allocators / deallocators
  when creating/freeing virDomainObjPtr instances.

a3adcce795 Convert virDomainObjListPtr to use a hash of domain objects
The current virDomainObjListPtr object stores domain objects in
an array. This means that to find a particular objects requires
O(n) time, and more critically acquiring O(n) mutex locks.

The new impl replaces the array with a virHashTable, keyed off
UUID. Finding a object based on UUID is now O(1) time, and only
requires a single mutex lock. Finding by name/id is unchanged
in complexity.

In changing this, all code which iterates over the array had
to be updated to use a hash table iterator function callback.
Several of the functions which were identically duplicating
across all drivers were pulled into domain_conf.c

* src/conf/domain_conf.h, src/conf/domain_conf.c: Change
  virDomainObjListPtr to use virHashTable. Add a initializer
  method virDomainObjListInit, and rename virDomainObjListFree
  to virDomainObjListDeinit, since its not actually freeing
  the container, only its contents. Also add some convenient
  methods virDomainObjListGetInactiveNames,
  virDomainObjListGetActiveIDs and virDomainObjListNumOfDomains
  which can be used to implement the correspondingly named
  public API entry points in drivers

1acef95a81 libvirt-devel should only require libvirt-client
There's a long known issue where if you install libvirt in a guest,
the default virtual network will conflict with the default virtual
network in the host.

That's one of the reasons we have the libvirt-client RPM - it allows
you to install the client library without having the host side
installed.

Rich Jones points out that if you install libvirt-devel in a guest,
then you get libvirtd installed and the network conflict:

  https://bugzilla.redhat.com/531200

libvirt-devel should only require libvirt-client - e.g. nothing in
the devel package pertains to anything in the libvirt RPM. The Fedora
packaging guidelines say:

  https://fedoraproject.org/wiki/Packaging/Guidelines#Devel_Packages

  Devel packages must require the base package using a fully versioned
  dependency ...

But for all intents and purposes, libvirt-client is our base RPM.

* libvirt.spec.in: make libvirt-devel require libvirt-client

936565c701 Add support for an external TFTP boot server
This patch adds an optional attribute to the <bootp> tag, that
