esx: Generate implicit _this macros
Several vSphere API methods are called on global objects like the
FileManager, the PerformanceManager or the SearchIndex. The generator
input file allows to mark such methods and the generator generates
such method in a way that automatically handles marked parameter. This
is done by some special macros. Those were manually written and this
patch moves them to the generator.

remote: Use virDomainEventState helpers
One functionality change here is that we no longer force enable the event
timeout for every queued event, only enable it for the first event after
the queue has been flushed. This is how other drivers have already done it,
and I haven't encountered problems in practice.

domain: Require <init> for container guests
Use capabilities to allow a driver to register a default <init> if none
is specified in the XML. Openvz was already open-coding this to be /sbin/init
LXC currently falls over if no init is specified, so an explicit error is
an improvement IMO.
(Side note: I don't think we can set a default value for LXC. If we use
/sbin/init but the user doesn't specify a separate root FS for their guest,
the container will rerun the host's init which can be traumatic :). For
virt-install I'm thinking of defaulting to /sbin/init if a root FS has
been specified, otherwise require the user to manually specify <init>)

(from glibc NEWS)
Thus with recent glibc, we need to try linking with -ltirpc when looking
for the XDR functions. The daemon also needs to use XDR_CFLAGS to be able
to find the XDR headers stored in /usr/include/tirpc.
When using TI-RPC, there are some warnings about redundant declarations, but
the fix probably belongs in other modules:

Recent versions of Xen disable the virtual HPET by default. This is
usually more precise because tick policies are not implemented for

provide the knob while leaving the default to "enabled" for compatibility
reasons.

the word, it is easier to rename them to .h for automake's sake.
