Subject: ldr_split_line() performance regression

magnum -

There's some ridiculous stuff in ldr_split_line() in jumbo now, such as
repeated uses of cfg_get_bool().  This (or/and something else) made JtR
unusably slow for me when not forcing a specific format.  Just try
running it on pw-fake-unix from:

without requesting any format.  It takes tens of seconds to load that
tiny file now, which was previously loaded instantly.

Please keep any non-trivial processing out of ldr_split_line(), or at
least limit it to only be done once (e.g., by using static variables).
