Use known length to pre-initialize buffer
... and drop now-obsolete conditional include, which is included
unconditionally since commit 4c68c4b93c41c4e9c2d5faf6c02ece2d40e95eb4

misaligned-pointer-use
Change nCount argument to sal_Int32, since that's what is used for
string lengths. The call sites use sal_uInt16 and sal_uInt8 as the
argument value.
