for the first time ever, this is a single script.
with recent simplifications in how variables are
handled, and techniques i've developed during
auditing, it's now feasible design-wise for this
to be a single script, without a helper script.

slight sloccount reduction. light renaming of
functions between the two scripts, placing more
logic in main() under include/boot.sh

errors are not defined for mktemp, and the /tmp file
system should be assumed reliable.

if /tmp is *unreliable*, then this is not something that
lbmk either can or should fix; the user clearly has
bigger problems.

manpages for mktemp do not define errors. it is assumed
to be completely reliable.

Instead of having detailed error messages, run most
commands through a function that calls err() under
fault conditions.

Where detail is still required, err() is still called
manually. Where it isn't, the error message is simply
whatever command was executed to cause the error.

This results in a massive sloccount reduction for lbmk;
specifically, 178 sloc reduction, or a 8.1% reduction.
The total sloccount is now 2022, for shell scripts.

also: further reduce the number of arguments passed,
to certain functions as and when feasible, in cases
where those are global variables that never change.

the cbfstool argument in mkUbootRom wasn't even used.
that function was only using the global variable, which
again is only set once.

i also shortened a few messages, removed a few errant
line breaks and reduced sloccount by exactly 1 in main()
by re-arranging how the shift command is used.

it's mainly about shortening variable names, to then
reduce the number of line breaks, but it's a surgical
code size reduction in build/boot/roms.

These are only ever initialised globally, and set once.
Other instances where they are set are only in cases
where they are passed as argument, at the start of
a function, so they are being *needlessly* re-set.

Set them only once and use them globally.
