set symbol for builtin name using rangelist

... so that the massive number of the JDBC driver's calls to JNI Attach/Detach-
CurrentThread are guaranteed not to happen on the main thread (where they are
extremely expensive, see
<http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6978641> "Fix for 6929067
introduces additional overhead in thread creation/termination paths").

Only redirect to valgrind.log if --valgrind but not $VALGRIND is given.

Cherry-picked from libreoffice-3-5 branch, probably a bit more helpful fail
message.

the idea behind this concept:
* have a file containing some test data
* import file without UI
* export file to svg through XStorable::storeToURL
* compare exported svg file to a reference file and complain if they
* differ

advantages:
* easy to create test cases, even for non coders
* no special handling of sd internal code needed
* svg is showing differences in the representation and not in the model
* external programs that can be used to check the output
* can be used for all input formats

disadvantages:
* changes to svg filter code might break test cases while the change is
correct
* slow test, import + export
* might need external program for xml diff

Also, removed unnecessary reloading of the whole table data when
reference is updated.

For efficiency reasons.  Otherwise, refreshing n tables individually
would require reloading the same data cache n times.

With this change, ScDPCacheTable should never clear pointer to the
data cache instance; it should keep the same data cache instance that
it is instantiated with.

Sigh, spent one day, more or less, tracking down a weird fontconfig
problem, where all the diagnostic it offered was "unknown encoding"
when reading the fonts.conf file.

It turned out that I was being screwed by our fun two versions of the
expat_xmlparse library: One where XML_Char is char and one where it is
short. The intuitively "more normally" named libexpat_xmlparse is the
latter, but fontconfig works only with the former as it implicitly
expects XML_Char to be char.
