Allow multipart property values
At present each property definition in a dts file must give as the
value either a string ("abc..."), a bytestring ([12abcd...]) or a cell
list (<1 2 3 ...>). This patch allows a property value to be given as
several of these, comma-separated. The final property value is just
the components appended together. So a property could have a list of
cells followed by a string, or a bytestring followed by some cells.
Cells are always aligned, so if cells are given following a string or
bytestring which is not a multiple of 4 bytes long, zero bytes are
inserted to align the following cells.
The primary motivation for this feature, however, is to allow defining
a property as a list of several strings. This is what's needed for
defining OF 'compatible' properties, and is less ugly and fiddly than
using embedded \0s in the strings.
