FACTOR: Mark translatable string as not a printf format string.
gettext uses a heuristic to guess whether a translatable string is a printf
format string. In this case, it guesses wrong, so add a comment that tells
gettext that "% of Variance" is not a format string.
Without this change, the translationproject.org robot rejects translations.

Greatly simplify PSPP configuration.
This gets rid of the "devices" configuration file entirely. Now you
can make pspp output to, for example, an HTML file, by invoking it as
"pspp -o out.html". Please read the documentation for full information.
It would be good to have a way to read options from a file to support,
for example, the IBM-PC or Unicode line drawing characters as implemented
in "devices" in previous versions. I hope that we can introduce that
soon.

pspp: Fix interactive usability for multi-line commands.
Until now, the terminal UI has only flushed output just before reading
the first line of a command. This generally worked OK because typically
only the final command produced output, not intermediate lines. But now
every line of a command potentially produces output (e.g. the command name
or the command syntax). With the ASCII driver that makes the interface
difficult to use because it typically opens and holds open a pipe to an
interactive program such as "more", which in turn turns off terminal echo
etc.
Flushing output before reading each command avoids this problem and makes
the terminal UI more usable.

ascii: Fix closing pipe files in ascii_destroy().
Files that are opened with fn_open() must be closed with fn_close(), but

message: Fix corner case in msg_emit().
In most cases, msg_emit() initialized the "where" member of the message
passed in. However, if msg_init() had not yet been called, it did not do
this. This fixes that corner case.
In addition, one caller of msg_emit() did not initialize these members. It
is not necessary for both msg_emit() and its callers to do so, but since
most callers did so, this commit simply makes the remaining caller do so
as well, for consistency.

message: Make msg_dup() copy and msg_destroy() free the file name.
This fixes a PSPPIRE bug in its message handling (found by inspection). It
makes copies of messages to use later. The file names were not being
copied, so in the meantime it was posible that they would be freed,
yielding a use-after-free error.
Since doing this sensibly required changing the file_name member of
struct msg_locator from "const char *" to "char *", it also touches up
places where this caused new warnings.

New library for interned strings.
An "interned" string is stored in a global hash table. Only one copy of any
given string is kept in the hash table, which reduces memory usage in cases
where there might otherwise be many duplicates of a given string.
Interned strings can be compared for equality by comparing pointers, which
can also be a significant advantage in some cases.
Interned strings are immutable.
This commit adds a general-purpose implementation of interned strings and
adapts the implementation of value labels, which already had a
special-purpose and less convenient implementation of interned strings,
to use them.

Rewrite PSPP output engine.
This rewrite makes the PSPP output engine much more object-oriented and
extensible than previously. It should make it much easier to add new
output features, such as cell footnotes and nested tables. It also makes
minimal changes to code that currently uses the output engine. The largest
changes are to the implementation of the LIST procedure, which are
necessary because this procedure had a too-intimate relationship with the
details of the output drivers.
The cairo and ascii drivers are now much better at breaking large cells and
large tables across pages and at choosing appropriate sizes for rows and
columns.
This commit adds a new output driver called "csv", which presents output
in comma-separated value format. It also updates all of the test cases
that produce output to use this output format.
This commit enhances the HTML output significantly and the ODF output
slightly.
This commit adds support for charts to the GUI output. However, it
temporarily removes the tree-view output summary pane from GUI output. It
should not be difficult to restore this later.
