data-in: Rewrite logic for recoding input, and get rid of src_enc member.
The logic used here seemed actually wrong for non-binary numeric formats
and AHEX format: we want these translated into the native encoding so that
we can interpret digits and letters properly without additional work.
The only case where we care about the output encoding is A format.

message: Add column range to struct msg_locator.
data_in() can specify a range of columns for the messages that it outputs,
but until now these were not output in the format specified by the GNU
Coding Standards. This commit fixes that.

message: Consistently initialize locator; use 0 for "no line number".
A few of the callers of msg_emit() did not initialize the "where" member
of the struct msg, because they expect that msg_emit() will do it for them.
This is currently correct, but I intend to soon introduce the ability for
msg_emit()'s caller to specify a location. With that change, it will be
important for the caller to initialize this member, so this commit makes
sure of that.
At the same time, some callers were using -1 as the default value that
means "no line number" and others were using 0. This commit standardizes
on the latter.

lexer: Improve translatability of lex_error().
In general I believe that it is easier to translate full sentences or
clauses. It seems likely that "Syntax error %s at %s." where the first
%s is an arbitrary English phrase would be impossible to translate
grammatically into some languages, so this changes the general form to
"Syntax error at %s: %s." which seems more likely to be translatable while
not changing the English meaning.

i18n: Handle EINVAL more gracefully.
EINVAL indicates an invalid multibyte sequence at the end of buffer. It
seems to me that there is no point in swallowing up a single byte and going
on at that point; instead, one might as well just declare the conversion
done after adding the fallback character. This is what this commit does.

i18n: Properly restart conversion when output buffer overflows.
The E2BIG case tries to restart the whole conversion, by reinitializing
all variables to their initial states. However the value of 'text' might
already have been advanced somewhat if there was a previous loop for e.g.
an invalid character. This commit fixes the problem by keeping the
original 'text' around and using a moving input pointer instead.

Suppress warnings about conversions between char * and unsigned char *.
For some time PSPP has used "unsigned char *" for string data and "char *"
for most other strings. Transforming between these properly generally
involves recoding, and there are some places where this is possibly
missing. The usual way to "fix" these warnings would be to insert casts,
but this would not fix the problem, just suppress the warnings, and it is
difficult to "grep" for casts so they would be hard to find for fixing
later.
This commit doesn't actually fix the problems, but it does suppress the
warnings while making them easy to find later: just grep for CHAR_CAST_BUG.

Until now the difference between the current and global settings for
