Modified files:
	posix          : regcomp.c 

Log message:
	(free_bin_tree): Removed.
	(create_tree): Add dfa argument.  Don't call re_malloc for
	each tree, instead allocate from str_tree_storage.
	(re_dfa_add_tree_node): New function.
	(free_dfa_content): Handle freeing if dfa->nodes == NULL
	or dfa->state_table == NULL.
	(re_compile_internal): Call free_dfa_content if init_dfa
	fails.  Call free_workarea_compile, re_string_destruct
	and free_dfa_content for most of the other failure paths.
	(init_dfa): Initialize str_tree_storage_idx.
	Don't clear any fields on allocation failure.
	(free_workarea_compile): Free str_tree_storage chunks
	instead of free_bin_tree (dfa->str_tree).
	(parse): Call re_dfa_add_tree_node instead of re_dfa_add_node
	followed by create_tree.  Add dfa argument to remaining
	create_tree calls.  Remove new_idx variable.  Remove calls
	to free_bin_tree.
	(parse_reg_exp, parse_branch, parse_expression, parse_sub_exp,
	parse_dup_op, parse_bracket_exp, build_charclass_op): Likewise.
	(duplicate_tree): Remove calls to free_bin_tree, add dfa
	argument to create_tree.
