macros around strings that were missing them.

after an unknown or failed psql backslash command, and also while
discarding "extra" arguments of a putatively valid backslash command.
In the case of an unknown/failed command, make sure we discard the
whole rest of the line, rather than trying to resume at the next
backslash.  Per discussion with Thomer Gil.

This prevents the next psql prompt from showing up on the end of the
last history line.

Make password error message a #define and use it consistently.

control-z requirement.

There are various things left to do: contrib dbsize and oid2name modules
need work, and so does the documentation.  Also someone should think about
COMMENT ON TABLESPACE and maybe RENAME TABLESPACE.  Also initlocation is
dead, it just doesn't know it yet.

conversion of basic ASCII letters.  Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower.  These functions use the same notions of
case folding already developed for identifier case conversion.  I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent.  Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.

errors in internally-generated queries, such as those submitted by
plpgsql functions.  Per recent discussions with Fabien Coelho.

recent discussion.  The lexer is used for both SQL command text and
backslash commands.  The purpose of this change is to make it easier to
track the behavior of the backend's SQL lexer --- essentially identical
flex rules are now used by psql.  Also, this cleans up a lot of very
squirrelly code in mainloop.c and command.c.  The flex code is somewhat
bulkier than the removed code, but should be lots easier to maintain.

cases involving writes.  Per recent discussion about the possibility
of close-time failures on some filesystems.  There is a TODO item for
this, too.

pg_malloc, to avoid linker failures on same platforms.

little more sane. Some parts of the code was using a static function
xmalloc() that did safe memory allocation (where "safe" means "bail
out on OOM"), but most of it was just invoking calloc() or malloc()
directly. Now almost everything invokes xmalloc() or xcalloc().

I thought I'd fixed this earlier, but I didn't get it right ...

so it won't miss 'em again.
