ti-eula-unpack: Add support for general binary installers.

* ti-unpack.inc has been created to allow support for general binary
  installers by creating a variable which is used to pass arbitrary
  arguments to the executable.
* ti-eula-unpack.inc sets the default arguments to retain support for
  recipes which still use this feature.

+# This file defines function used for unpacking the .bin file downloaded over
+# the http.
+#  BINFILE - name of the install jammer .bin file
+#  TARFILE - name of the tar file inside the install jammer
+#  TI_BIN_UNPK_ARGS   - contains the arguments to be passed to the bin file.
+#  TI_BIN_UNPK_CMDS   - contains list of commands separated with colon to be 
+#                       passed while unpacking the bin file. The keyword 
+#                       workdir expands to WORKDIR and commands are appendded
+#                       with '\n'. Eg. TI_BIN_UNPK_CMDS="Y:Y: qY:workdir"
+#  TI_BIN_UNPK_WDEXT  - This variable extends workdir path, if user wants to put
+#                       the output in some internal directory
