Olaf Hering 687121f8a0 xl: optionally print timestamps when running xl commands 
Add a global option "-T" to xl to enable timestamps in the output from
libxl and libxc. This is most useful with long running commands such
as "migrate".

During 'xl -v.. migrate domU host' a large amount of debug is generated.
It is difficult to map each line to the sending and receiving side.
Also the time spent for migration is not reported.

With 'xl -T migrate domU host' both sides will print timestamps and
also the pid of the invoked xl process to make it more obvious which
side produced a given log line.

Note: depending on the command, xl itself also produces other output
which does not go through libxentoollog. As a result such output will
not have timestamps prepended.

This change adds also the missing "-t" flag to "xl help" output.

Paul Durrant e465fecbfd xl: allow domid to be preserved on save/restore or migrate 
This patch adds a '-D' command line option to save and migrate to allow
the domain id to be incorporated into the saved domain configuration and
hence be preserved.

NOTE: Logically it may seem as though preservation of domid should be
      dealt with by libxl, but the libxl migration stream has no record
      in which to transfer domid and remote domain creation occurs before
      the migration stream is parsed. Hence this patch modifies xl rather
      then libxl.

Anthony PERARD edaa631ddc libxl: Make libxl_domain_unpause async 
libxl_domain_unpause needs to make QMP calls, which are asynchronous,
change the API to reflect that.

Do the same with libxl_domain_pause async, even if it will keep
completing synchronously.

Also fix some coding style issue in those functions.
