This split the mangling code up to allow for the possibility of multiple
mangling implementation, selectable using "mangling method = " in smb.conf It also tidies the interface a little, although it is still nasty. (This used to be commit be23d87a178e7d0691e7d942adf89bb3d2d533c2)

- * MANGLE_BASE - This is the number of characters we use for name mangling.
- *
- * basechars - The set characters used for name mangling. This
- * is static (scope is this file only).
- *
- * mangle() - Macro used to select a character from basechars (i.e.,
- * mangle(n) will return the nth digit, modulo MANGLE_BASE).
- *
- * chartest - array 0..255. The index range is the set of all possible
- * values of a byte. For each byte value, the content is a
- * two nibble pair. See BASECHAR_MASK and ILLEGAL_MASK,
- * below.
- *
- * ct_initialized - False until the chartest array has been initialized via
- * a call to init_chartest().
- *
- * BASECHAR_MASK - Masks the upper nibble of a one-byte value.
- *
- * ILLEGAL_MASK - Masks the lower nibble of a one-byte value.
- *
- * isbasecahr() - Given a character, check the chartest array to see
- * if that character is in the basechars set. This is
- * faster than using strchr_m().
- *
- * isillegal() - Given a character, check the chartest array to see
- * if that character is in the illegal characters set.
- * This is faster than using strchr_m().
- *
- * mangled_cache - Cache header used for storing mangled -> original
- * reverse maps.
- *
- * mc_initialized - False until the mangled_cache structure has been
- * initialized via a call to reset_mangled_cache().
- *
- * MANGLED_CACHE_MAX_ENTRIES - Default maximum number of entries for the
- * cache. A value of 0 indicates "infinite".
- *
- * MANGLED_CACHE_MAX_MEMORY - Default maximum amount of memory for the
- * cache. When the cache was kept as an array of 256
- * byte strings, the default cache size was 50 entries.
- * This required a fixed 12.5Kbytes of memory. The
- * mangled stack parameter is no longer used (though
- * this might change). We're now using a fixed 16Kbyte
- * maximum cache size. This will probably be much more

+ * magic_char - This is the magic char used for mangling. It's

+ *
+ * MANGLE_BASE - This is the number of characters we use for name mangling.
+ *
+ * basechars - The set characters used for name mangling. This
+ * is static (scope is this file only).
+ *
+ * mangle() - Macro used to select a character from basechars (i.e.,
+ * mangle(n) will return the nth digit, modulo MANGLE_BASE).
+ *
+ * chartest - array 0..255. The index range is the set of all possible
+ * values of a byte. For each byte value, the content is a
+ * two nibble pair. See BASECHAR_MASK and ILLEGAL_MASK,
+ * below.
+ *
+ * ct_initialized - False until the chartest array has been initialized via
+ * a call to init_chartest().
+ *
+ * BASECHAR_MASK - Masks the upper nibble of a one-byte value.
+ *
+ * ILLEGAL_MASK - Masks the lower nibble of a one-byte value.
+ *
+ * isbasecahr() - Given a character, check the chartest array to see
+ * if that character is in the basechars set. This is
+ * faster than using strchr_m().
+ *
+ * isillegal() - Given a character, check the chartest array to see
+ * if that character is in the illegal characters set.
+ * This is faster than using strchr_m().
+ *
+ * mangled_cache - Cache header used for storing mangled -> original
+ * reverse maps.
+ *
+ * mc_initialized - False until the mangled_cache structure has been
+ * initialized via a call to reset_mangled_cache().
+ *
+ * MANGLED_CACHE_MAX_ENTRIES - Default maximum number of entries for the
+ * cache. A value of 0 indicates "infinite".
+ *
+ * MANGLED_CACHE_MAX_MEMORY - Default maximum amount of memory for the
+ * cache. When the cache was kept as an array of 256
+ * byte strings, the default cache size was 50 entries.
+ * This required a fixed 12.5Kbytes of memory. The
+ * mangled stack parameter is no longer used (though
+ * this might change). We're now using a fixed 16Kbyte
+ * maximum cache size. This will probably be much more
