Log Message:
-----------
barcode: update to 0.99

Additionally:
 - Drop Debian patches that have neither been submitted upstream nor have
   a good description of why they are necessary
 - Apply patches that fix two build problems
 - Reorganize the Portfile a bit, use modern checksums
 - Rename the ${prefix}/bin/sample binary to ${prefix}/bin/barcode-sample

+Providing a global declaration without "extern" in a header adds a symbol with
+that name to every compilation unit that includes the header. Consequently,
+some compilers (e.g., clang) fail to link more than one of these compilation
+units because there are two versions of the "streaming" symbol. Fix this by
+moving the declaration to pcl.c and keeping changing the one in the header to
+be extern.
