bc: handle BIN_FILE and LEX_BAD_CHAR errors at the site of detection
...
The most informative message can be generated at the location
where error is detected. The "error codes" are stupid:
print error meesage immediately, then just return "there was an error"
indicator.
All error codes will be converted. For now, converting these two.
For now, this and following changes will degrade error messages
quality. For example, file name and line number printouts may be lost.
This will be re-added later.
This change anlso fixes handling of invalid stdin input:
this used to cause interactive bc to exit:

bc: only check for ^C in bc_program_exec() main loop
...
Checking it in individual operations such as SQRT is not necessary
since they usually do not take very long to complete. We repeatedly return
to main loop.
TODO: re-add more fine-grained ^C checks - but only with examples where it is
actually needed. E.g. I suspect simplest ops like addition or compare won't need it.

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.

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.

The buffer that is sent is also 3 bytes too long due to those extra 3
