Update rrdtool from 1.2.27nb1 to 1.3.0nb1.

Local change warranting nb1 is to prefix some error messages from
rrdupdate with the name of the file the error relates to, carried
over from nb1 of 1.2.27.

Update loosely OKed by martti@

The announcement of 1.3.0 outlines the changes since 1.2.27:


NEW Fast file access methods (Bernhard Fischer / Tobi Oetiker)
----------------------------
* introduced file-accessor functions rrd_read/rrd_seek/rrd_write

* implemented full mmap-based file access with madvise hints for
  improved scalability, much reduced memory-footprint and much less
  blocking while accessing the disk

* implemented optional full file-descriptor access instead of FILE*
  access

NEW Graphing (Tobi Oetiker)
------------
* libart has been replaced by cairo/pango

* pango markup is supported (--pango-markup)

* full grid fitting

* --graph-render-mode=mono for non anti aliased graphing

* --font-render-mode=mono for non anti aliased fonts

* fonts come through fontconfig, use the Pango font nameing scheme
  -> 'Times 20' ... it is not possible to use truetype fonts
  directly anymore.

* Tabs are position independent.

* TRENDNAN filter that ignores NAN values while calculating the
  TREND data. (Timo Stripf)

* --full-size-mode to specify the outer border of the image and not
  just of the graphing canvas (Matthew Chambers)

* TEXTALIGN command to alter default text alignment behavior

* C API in-memory graphing with rrd_graph_v (Evan Miller)

* draw dashed lines in graphs (Thomas Gutzler)

* new interface graphv which returns information using the rrd_info
  interface (Tobi Oetiker and Mark Plaksin)

* improved horizontal grid. Have a bit more grid lines and y-axis
  labels while keeping them far enough apart to not run into each
  other.

NEW Forecasting (Evan Miller)
---------------
* the new MHWPREDICT consolidation function uses a variation of the
  Holt-Winters method. It is a drop-in replacement for HWPREDICT,
  and is better suited for data whose seasonal variations grow or
  shrink in proportion to the average.

* If you create an RRD with the new MHWPREDICT function, the
  resulting rrd file will be version 0004 and can only be used in
  rrdtool 1.3.

Rewrites
--------
* rrd_restore now uses libxml for parsing which makes things much
  more tolerant towards xml variations. The old code could mostly
  just parse the XML as it was output by rrdtool dump. See also:
  the note at the bottom of this document. (by Florian octo
  Forster)

* rrd_update rewritten to make it more modular. Fixed two
  longstanding HW bugs in the process (Evan Miller)

Internationalization (Takao Fujiwara and Tobi Oetiker)
--------------------
* The help output by rrdtool has been internationalized. There are
  no real translations included with rrdtool yet, contributions are
  welcome.

* The internationalization will only be compiled if libintl and
  friends are available on your system. Use the configure option
  --disable-libintl if you want to disable this feature

Language Bindings
-----------------
* ruby rrd_fetch will return step as a last property -- Mike Perham

RRDtool dump / restore incompatibility
--------------------------------------
* rrdtool dump 1.3 does emit completely legal XML. Basically this
  means that it contains an XML header and a DOCTYPE definition.
  Unfortunately this causes older versions of rrdtool restore to be
  unhappy.

* To restore a new dump with an old rrdtool restore version, either
  remove the XML header and the doctype by hand (both on the first
  line of the dump) or use rrdtool dump --no-header.
