sysstat version 11.7.1 final packaging.
lsm and spec files updated.
Changelog added.
NOTE: Stable versions (11.2.14 [EOL], 11.4.8 and 11.6.2) also exist
and will be available for download from my web site:

The stable versions include only the bug fixes added in sysstat 11.7.1
but not the new features.
Version 11.7.1 includes major changes concerning sar's binary data
file format and how sar works. Among them:
* A binary data file should take much less space on disk thanks
to new optimizations on how values are stowed in memory. The space saved
is estimated at least at 25% compared to previous format.
* Structures are no longer statically allocated, meaning that
the system can now register as many new devices (disks, network
interfaces, etc.) as needed and you will find all of them saved in your
saXX data file (provided that you have selected the corresponding
activities to collect). Previous version could lead to some devices
being ignored and going unnoticed if no free structures were left.
* Sar (and sadf) will now be able to read a binary data file
whatever its endianness is: Both big-endian and little-endian files can
be read by the same sar or sadf executable.
* More flexibility has been added to sar's binary data file
format. I cannot promise that the format won't change again in the
future but it should now be possible to add new metrics or activities
without making the format unreadable by older sar versions (starting
with version 11.7.1). Older versions will be able to read newer formats
but will display only the metrics they currently know.
Version 11.7.1 is a development version. As such, it is still NOT ready
for use in production. Yet I would really like to have it tested by the
maximum number of users and get feedback! :-)
NOTE: The function provided by sadf (option -c) to convert an old
data file to the up-to-date format has been temporarily inhibited. This
function will be working again in next sysstat version (11.7.2).
