This reverts commit 674a40fe830748b63eafeaf07e0932e2e0a81ba6.

And restores a95cce27 with the exception
that the sal_Int8 to sal_uInt16 change is omitted.

This stream length change causes loading of autoformats to fail, which
are stored in binary format, i.e. in user config's autotbl.fmt, loaded
and stored in Calc's ScAutoFormat sc/source/core/tool/autoform.cxx and
Writer's SwTableAutoFmtTbl sw/source/core/doc/tblafmt.cxx
