data-out: Optimize and fix some bad assumptions.
Until now, data_out_pool() and its wrapper function data_out() have always
done at least two memory allocations: one to fill in the initial version
of the result and another to recode it to UTF-8. However, recoding to
UTF-8 is usually unnecessary, because most output formats always produce
output in UTF-8 anyway. Only binary formats and the string A format ever
produce data in other encodings, so this commit drops recoding entirely
except for those cases. Binary formats are a particularly special case:
usually it doesn't make any sense to use these formats for text output,
but this commit does its best to translate the binary output bytes into
valid UTF-8, at least up to the first null byte.
This commit also finishes fixing up display widths.
The closely related data_out_legacy() function, which only has one user
in three also needed some work. It was badly named, so I renamed it to
data_out_recode(). It made the bad assumption that the data passed in
was encoded in ASCII (written C_ENCODING). It also made the bad
assumption that the number of bytes output would be exactly the format's
width. This rewrite fixes these problems.

or three bytes, respectively, in UTF-8, while occupying only a
single display column.

there are still some higher-level issues, but that will come in
a later commit when those remaining issues are resolved.

make more sense after the following commit, which adds another member

Until now, every converter has produced output that is exactly as many

require multiple bytes. In preparation, this commit requires the
individual converters to write out their own null byte, giving a bit
more flexibility regarding length.

categoricals: Make parameter to categoricals_done() const.
From a high-level point of view, categoricals_done() does not actually
mutate any data in a categoricals object. Instead, it just computes a
cache. So it seems reasonable to make it take a "const" parameter, and
this fixes a warning:

covariance: Fix const-ness of covariance_calculate[_unnormalized] retval.
The covariance_calculate() and covariance_calculate_unnormalized()
functions documented that their return values were owned by the covariance
object itself and thus should not be freed by the caller. However, this
documentation was incorrect, because in fact the covariance object did not
retain the pointer at all. This commit fixes the comments, updates
the return values to be non-"const", and changes the callers to free the
returned "gsl_matrix" objects.

On my machine GCC 4.4 complains:
friedman.c: In function ‘friedman_execute’:

This appears to be because GCC can't see that the assignment to fr.w and

rate, this commit suppresses the warning by always initializing fr.w.

Remove the PROMPT, CPROMPT, and DPROMPT settings.

lexer, which is able to detect more special cases in syntax and report
them through the prompt. (However, if users actually want this feature,
then we could add it; it's not difficult.)

lexer: Change the functions for retrieving token strings.
Until now, lex_tokid() has been for T_ID tokens only and lex_tokstr() has
been for T_ID and T_STRING tokens. For T_ID tokens, lex_tokid() and
lex_tokstr() had slightly different semantics.
This doesn't entirely make sense, and these particular functions are not
the ones wanted most by clients, so this commit removes these functions
in favor of lex_tokcstr() and lex_tokss(), which are both applicable
to both T_ID and T_STRING tokens, with the same semantics in each case.
These functions are also easier for the upcoming reimplementation of the
lexer.

lexer: Get rid of lex_negative_to_dash().
This function stands in the way of replacing the lexer in a
straightforward way, because it disrupts the stream of tokens: the
lexer can't tell in advance whether, e.g., "-4" is one token or
two. Fortunately, it is not used in very many places and is
relatively easy to remove.

lexer: New type enum token_type.
It seems useful to have a type that indicates that a value is a token.
Furthermore, being able to enumerate all of the possible tokens in a
straightforward way seems worthwhile. It also makes it possible for
GCC to check "switch" statements on token types and to build arrays
indexed by token.

command: Factor command name matching out of command.c.
Making command parsing into a library will allow other code to use
the same functionality, which will be useful later in the lexer.
It also simplifies parsing command names and allows us to easily
add tests for command name parsing.
The new command name parsing code supports UTF-8. This is not useful yet,
because its only client does not feed it UTF-8 strings, but it will be
useful later when the rest of the lexer is rewritten, where it will gain
another client that does feed it UTF-8.

perl-module: Fix return value of append_case subroutine.
The casewriter_write() function does not have a return value (it is
declared as "void"), but the append_case subroutine tried to use its
return value anyway. This cannot work properly, of course, and in fact
caused problems on 64-bit builds in particular.
I don't know why there is no C compiler warning about this problem. I
guess the Perl module build must somehow turn off a lot of GCC warnings.
