note: me6_update_parser needs to be written, similar
to me7_update_parser, to generate the partition
tables within intel me6 on lenovo bios updates.

the current logic in lbmk goes like this:
mkdir -p vendorfiles/cache/

and save your factory dump as:
vendorfiles/cache/x201_factory.rom

the build system has been modified, in such a way
as to support extracting me.bin (which is the full
one) and then neutering from this.

this is done automatically, if the file is present,
but you must first insert that file there, which means
you'll need a dump of the original boot flash on your
thinkpad x201

in some cases, use of x_ or xx_ can be error-prone,
due to the way $@ is handled; commands requiring
quotes, or with funny file names as arguments such
as spaces in the file name, or other special
characters, can make the x/xx functions break.

in those cases, where x/xx must not be used, the
commands use || err instead

in other cases, use of x/xx is superfluous, and has
been removed in some commands.

as opposed to the current 3-level structure.

recent build system simplifications have enabled
this change, thus:

./build fw coreboot -> ./build roms
./build fw grub -> ./build grub
./build fw serprog -> ./build serprog
./update project release -> ./update release
./update project trees -> ./update trees
./update vendor download -> ./vendor download
./update vendor inject -> ./vendor inject

alper criticised that the commands were too long,
so i made them shorter!
