[LinuxBIOS] [PATCH] Rename "stream" to "payload"

[Ed Swierk]

After our discussion in the "Download payload from console via XMODEM"
thread, I posted these patches. There was no response, possibly due to
the LinuxBIOS conference.

Here they are again in case they were overlooked the first time
around, in increasing order of invasiveness:

The first patch renames CONFIG_COMPRESSED_ROM_STREAM* and
CONFIG_PRECOMPRESSED_ROM_STREAM.

The second one renames the other CONFIG_*_STREAM options.

The third one goes whole-hog and replaces every remaining instance of
"stream" with "payload" in code, filenames and directory names. The
diff is pretty huge due to the file renaming.
