785e4b3057 bc: propagate fixed arguments into callees
Looks like there is only one "BcProgram" object, &G.prog.

the result would not be as intended:

c339c7f7b3 libarchive: add a function to unpack embedded data
Similar code to unpack embedded data is used to decompress usage
messages, embedded scripts and the config file (in the non-default
bbconfig applet).

Moving this code to a common function reduces the size of the default
build and hides more of the internals of libarchive.

ca2f831ead hexedit: fixes for redraw and down movement causing SEGV on attempt to access
"Go to:" command was not updating row position, making next "down" movements
for one screenful print empty lines instead of showing the contents.

If the file is whole pages long, "down" movement at EOF was advancing position
+16 bytes, mapping the next portion (entirely past the end of the file),
then finding out that the new position is beyond the EOF, rolling it back
-16 bytes... ending up with this postion pointing *before* the mapped portion.
Any next access (e.g. "move right" key) SEGVs.

For some setups (E.G. for supporting different screen resolutions),

Add support for IMG_LEFT/IMG_TOP settings to specify the image location,
similar to how it is done for the progress bar.

b5d9ba8fe6 i2cset: fix 'i' & 's' modes (3 extra bytes were sent)
When 'i' or 's' modes are selected block array is filled from offset 3
(blen = 3) but copied to data.block buffer from offset 0 so first 3 bytes
contains garbage from stack.
The buffer that is sent is also 3 bytes too long due to those extra 3
bytes.

0d1eaf407c i2c-tools: don't include linux/i2c-dev.h
Installing headers from upstream i2c-tools makes it impossible to
build the busybox version due to redefined symbols. This is caused by
the fact that linux/i2c-dev.h from i2c-tools overwrites the one from
linux uapi and defines symbols already defined by linux' linux/i2c.h.

Drop this include and simply re-implement the relevant defines from
linux/i2c-dev.h in miscutils/i2c-tools.c.

Tested by building on systems with and without i2c-tools headers.
