are only macros to buffer_{append,copy}_long()
* ltostr() returns the string length instead of always 0
* Don't check return value of buffer_prepare_append(buffer *b), since
it only returns -1 if b == NULL, which we do a few lines above anyway.
* Improved buffer_path_simplify(). No "dot_stack" required anymore.
Operation can also be performed inplace.
* Check errno also against EACCES at pidfile-unlink for not logging
a "Permission denied".
