[PATCH] explicit Unicode data tables generation

[Thomas Wolff <towo at towo dot net>]

This patch adds explicit generation of Unicode data tables for 
libc/string/wcwidth, libc/ctype/tow* and libc/ctype/isw*
according to the explicit approach as requested by Corinna.
Feel free to adjust the make target name (now unidata) as desired.
A note should be added to newlib/README, like this:
The libc functions string/wcwidth, ctype/tow* and ctype/isw* use
character property data tables which are generated from Unicode data.
To regenerate them, especially to update to a new Unicode version,
run ‘make unidata’ in the newlib build target directory. The cygwin
package unicode-ucd should be installed to provide data tables during
this step. Alternatively, run ‘make unidate-download’ to download the
data directly from unicode.org and then generate the tables.
