Some windowmanagers on small devides do not have the close window button,
so all dialogs should have its own way how to diappear.
It is now done like in other application. They use "Close" button instead
of "OK". They put it into the right side and delimit it by a line, so
it looks like another dialog in the application.
* put back "supplied by %OOOVENDOR" instead of "developed by %OOOVENDOR"
* remove "LibreOffice is" from the copyright line. It has affect only when
the product is called "LibreOffice"
* center version and buildid line
* remove the confusing branch-point from buildid; it is not longer necessary
when we have the version suffix, e.g. beta1+
* cppheader.xsl had initially been written under the false assumption that a
missing oor:nillable attribute defaults to "false" instead of "true". That has
been fixed.
* As a result, many places that use the new simplified officecfg/*.hxx headers
broke as they did not expect value types to be wrapped boost::optional. To keep
the code simple, I decided to change all occurrences in
officecfg/registry/schema/ of properties that specify a default <value> and do
not explicitly specify oor:nillable="true" to oor:nillable="false". Strictly
speaking, this is an incompatible change, but in many cases it should be what
was intended, anyway.
* Some places that use the new simplified officecfg/*.hxx headers still had to
be adapted to boost::optional wrapping.
* This showed that unotools/configuration.hxx did not yet work for those wrapped
properties and needed fixing, too.
SAL_UNUSED_PARAMETER (expanding to __attribute__ ((unused)) for GCC)
is used to annotate legitimately unused parameters, so that static
analysis tools can tell legitimately unused parameters from truly
unnecessary ones. To that end, some patches for external modules
are also added, that are only applied when compiling with GCC and
add necessary __attribute__ ((unused)) in headers.
Our translation tools read the src files literally, line by line, only
reacting on specific patterns (e.g., 'Text [en-US] = "...";'). Therefore
use of macros like this cannot work.
