Generic cleanups
+- switch cli parsing to getopt
+- hunt for extern's and prototypes spread all over the source
+- merge old Makefile.profile.in back into Makefile.in if meaningful at all
+- use automake
+- drop gnushogi.lng, merge strings back into code
+- use version from configure.ac, get rid of version.h, drop patchlevel
- hunt for more hardcoded variant-specific constants
- position of captured pieces in curses mode
- compile with bound-checker
- add autosave mode to ease hunt for segfaults ?
-- generate patterns.inc at build-time
- use 2D array for the board, get rid of the (i)nunmap stuff
- fixup build procedure to support parallel make runs
- investigate those preexisting "overflow in implicit constant
* OPENING_HINT
- add minishogi stuff to the doc
- use valid minishogi moves in online help

-- segfault (on level 1) following 2e1d 1d4a
- => field.piece can reach 14 in pattern.c::update_advance_bonus
- => probably related to using patterns for standard shogi
- => must break the circular pattern.o <-> pattern.inc dep to
- be able to generated pattern.inc as needed
