Provide flags
XTL_STDIOSTREAM_PROGRESS_USE_CR
XTL_STDIOSTREAM_PROGRESS_NO_CR
to allow the caller to force, or disable, the use of \r-based
overwriting of progress messages.
In the implementation, rename the variable "tty" to "progress_use_cr".

As suggested by IanJ:
Check isatty only once to preserve the errno of ->progress users, and to
reduce the noice in strace output.

If the output goes to a tty, rewind the cursor and print everything in a
single line as it was done up to now. If the output goes to a file or
pipe print a newline after each progress output. This will fix logging
of progress messages from xc_save to xend.log.
To support XTL_STDIOSTREAM_SHOW_PID or XTL_STDIOSTREAM_SHOW_DATE print
the output via vmessage if the output is not a tty.

In xc_domain_save ensure that we signal completion at the end of each
batch.
This ensures that the next logged line starts on a new line. e.g. instead of:
Savefile contains xl domain config
xc: Saving memory: iter 3 (last sent 0 skipped 0): 0/32768 0%migration target: Transfer complete, requesting permission to start domain.
migration sender: Target has acknowledged transfer.
what is desired is:
Savefile contains xl domain config
xc: Saving memory: iter 0 (last sent 0 skipped 0): 32768/32768 100%
xc: Saving memory: iter 1 (last sent 32576 skipped 192): 32768/32768 100%
xc: Saving memory: iter 2 (last sent 217 skipped 0): 32768/32768 100%
xc: Saving memory: iter 3 (last sent 0 skipped 0): 32768/32768 100%
migration target: Transfer complete, requesting permission to start domain.
migration sender: Target has acknowledged transfer.

tools/libxc, tools/libelf: Relicense under LGPL v2.1
Relicense these two libraries under LGPL v2.1 only except where
individual files already included the "or later" provision.
Copyright holders have been contacted by Stephen Spector and have all
agreed this change.
Removed tools/libxc/ia64/aclinux.h since it appeared to be
unused. There is a separate, more up to date, copy in
xen/include/acpi/platform/aclinux.h which does appear to be used.
Clarify the license of MiniOS privcmd.h under the same terms as other
tools/include/xen-sys headers.

* Provide a new XTL_STDIOSTREAM_HIDE_PROGRESS flag in the stdio logger
* Provide a way to adjust the flags after logger setup
* Use these to disable progress output from the migration receiver, as
the sender is also sending progress information.

The -v option, which must come before the xl command, increases the
logging level each time it is supplied.

We provide a new header file "xentoollog.h" which defines an interface
that libraries and applications can use for logging. This avoids
having to wrap each library's log callbacks up, massage arguments to
log callbacks, and so on.
The library's .o files are within libxc to avoid having to create a
separate lib*.a, but callers do not need to #include xenctrl.h and it
should be regarded as a separate API.
