common: Allow building of mkdir_p.c for Windows.

Browse Source 
* common/mkdir_p.c: Change license and comment debug statements.
(amkdir_p, mkdir_p): Fail on malloc error and use default_errsource to
build an error code.  Change return value to gpg_error_t.
(amkdir_p): Use gnupg_mkdir.

* common/membuf.c: Include util.h first to avoid redefined macro
warnings.
