including important bug fixes

there is still a little wrinkle, the preview shell always shows what sheets are selected, it's currently not possible to specify the sheets to preview

This ports 84dbc4fe "do not let gcc use
registers we are setting ourselves," in the hope that it is also an
improvement for Mac OS X PPC.  (But the patch was applied blindly, so
please revert if it makes things worse instead.)

This reverts commit b8044cb8.

84dbc4fe fixed the bridge for PPC on Linux, not
Mac OS X.

The various *Card* members call getByIndex(rowIndex) and getByIndex expects
sal_uInt32 so change everything to it. Change callers as well to adapt to
the change.

index is passed to getByIndex which takes sal_uInt32 so just use sal_uInt32
everywhere

Clang says:
stripped_scanner.ll:198:46: error: for loop has empty body [-Werror,-Wempty-body]
stripped_scanner.ll:198:46: note: put the semicolon on a separate line to silence this warning [-Wempty-body]

gcc uses a register for the function call--and it tried r9 here...

The "mr" stores r11 to indeterminate register (r9 in my case) before
storing it into the output variable, thus overwriting one of our input
arguments... This later leads to nice segfault in
testtools/source/bridgetest ...

I suppose there is a better way to get the variable, but I do not know
it .-)

The copy/paste formulas code is getting a bit complex. I will try to
write some test cases for it.

The change:
-    if(m_GlyphsList.size()>1)
+    if(!m_GlyphsList.empty())
is incorrect, so change it back.
