 * This file is used to initialize various variables and arrays for the
 * Angband game.  Note the use of "fd_read()" and "fd_write()" to bypass
 * the common limitation of "read()" and "write()" to only 32767 bytes
 * at a time.
 * Several of the arrays for Angband are built from "template" files in
 * the "lib/file" directory, from which quick-load binary "image" files
 * are constructed whenever they are not present in the "lib/data"
 * directory, or if those files become obsolete, if we are allowed.
 * Warning -- the "ascii" file parsers use a minor hack to collect the
 * name and text information in a single pass.  Thus, the game will not
 * be able to load any template file with more than 20K of names or 60K
 * of text, even though technically, up to 64K should be legal.
 * The "init1.c" file is used only to parse the ascii template files,
 * to create the binary image files.  If you include the binary image
 * files instead of the ascii template files, then you can undefine
 * "ALLOW_TEMPLATES", saving about 20K by removing "init1.c".  Note
 * that the binary image files are extremely system dependant.

 * @brief 各データファイルを読み取るためのパスを取得する
 * Find the default paths to all of our important sub-directories.
 * @param path パス保管先の文字列
 * @return なし
 * @details
 * <pre>
 * The purpose of each sub-directory is described in "variable.c".
 * All of the sub-directories should, by default, be located inside
 * the main "lib" directory, whose location is very system dependant.
 * This function takes a writable buffer, initially containing the
 * "path" to the "lib" directory, for example, "/pkg/lib/angband/",
 * or a system dependant string, for example, ":lib:".  The buffer
 * must be large enough to contain at least 32 more characters.
 * Various command line options may allow some of the important
 * directories to be changed to user-specified directories, most
 * importantly, the "info" and "user" and "save" directories,
 * but this is done after this function, see "main.c".
 * In general, the initial path should end in the appropriate "PATH_SEP"
 * string.  All of the "sub-directory" paths (created below or supplied
 * by the user) will NOT end in the "PATH_SEP" string, see the special
 * "path_build()" function in "util.c" for more information.
 * Mega-Hack -- support fat raw files under NEXTSTEP, using special
 * "suffixed" directories for the "ANGBAND_DIR_DATA" directory, but
 * requiring the directories to be created by hand by the user.
 * Hack -- first we free all the strings, since this is known
 * to succeed even if the strings have not been allocated yet,
 * as long as the variables start out as "NULL".  This allows
 * this function to be called multiple times, for example, to
 * try several base "path" values until a good one is found.

 * @brief 全ゲームデータ読み込みのメインルーチン /
 * Hack -- main Angband initialization entry point
 * @return なし
 * @note
 * <pre>
 * This function is "messy" because various things
 * may or may not be initialized, but the "plog()" and "quit()"
 * functions are "supposed" to work under any conditions.
 * Verify some files, display the "news.txt" file, create
 * the high score file, initialize all internal arrays, and
 * load the basic "user pref files".
 * Be very careful to keep track of the order in which things
 * are initialized, in particular, the only thing *known* to
 * be available when this function is called is the "z-term.c"
 * package, and that may not be fully initialized until the
 * end of this function, when the default "user pref files"
 * are loaded and "Term_xtra(TERM_XTRA_REACT,0)" is called.
 * Note that this function attempts to verify the "news" file,
 * and the game aborts (cleanly) on failure, since without the
 * "news" file, it is likely that the "lib" folder has not been
 * correctly located.  Otherwise, the news file is displayed for
 * the user.
 * Note that this function attempts to verify (or create) the
 * "high score" file, and the game aborts (cleanly) on failure,
 * since one of the most common "extraction" failures involves
 * failing to extract all sub-directories (even empty ones), such
 * as by failing to use the "-d" option of "pkunzip", or failing
 * to use the "save empty directories" option with "Compact Pro".
 * This error will often be caught by the "high score" creation
 * code below, since the "lib/apex" directory, being empty in the
 * standard distributions, is most likely to be "lost", making it
 * impossible to create the high score file.
 * Note that various things are initialized by this function,
 * including everything that was once done by "init_some_arrays".
 * This initialization involves the parsing of special files
 * in the "lib/data" and sometimes the "lib/edit" directories.
 * Note that the "template" files are initialized first, since they
 * often contain errors.  This means that macros and message recall
 * and things like that are not available until after they are done.
 * We load the default "user pref files" here in case any "color"
 * changes are needed before character creation.
 * Note that the "graf-xxx.prf" file must be loaded separately,
 * if needed, in the first (?) pass through "TERM_XTRA_REACT".
