	* datrie/alpha-map-private.h, datrie/alpha-map.c:
	* datrie/darray.h, datrie/darray.c:
	* datrie/tail.h, datrie/tail.c:
	* datrie/trie.c (trie_fread, trie_fwrite):
	Rename *_read() and *_write() functions to *_fread() and *_fwrite(),
	for consistency with the trie_f{read,write}() function.

2010-06-28  Theppitak Karoonboonyanan  <thep@linux.thai.net>

	Add trie_fread() and trie_fwrite() interfaces for reading/writing trie
	data from an open file. Thanks NIIBE Yutaka <gniibe@fsij.org> for the
	suggestion.

	* datrie/trie.h (trie_fread, trie_fwrite): Add new API declarations.
	* datrie/trie.c (trie_new_from_file, trie_fread, trie_save,
	  trie_fwrite):
	Refactor open file handling of trie_new_from_file() and trie_save()
	into trie_fread() and trie_fwrite(), and make the old functions
	do file opening/closing as wrappers to them.
	* datrie/libdatrie.def, datrie/libdatrie.map: Add symbol exports.

2010-06-27  Theppitak Karoonboonyanan  <thep@linux.thai.net>
