vfscanf: Use struct scratch_buffer instead of extend_alloca
A custom character buffer is added in this commit, in the form of struct char_buffer. The char_buffer_add function replaces the ADDW macro (which has grown with each successive security fix). The char_buffer_add slow path is moved out-of-line, reducing code size. * stdio-common/vfscanf.c (MEMCPY): Remove macro. (struct char_buffer): New type. (char_buffer_start, char_buffer_size, char_buffer_error) (char_buffer_rewind, char_buffer_add): New functions. (ADDW): Remove macro, replaced by the char_buffer_add function. (_IO_vfscanf_internal): Rewrite using struct char_buffer instead of extend_alloca. Make control flow more explicit.
