New apr_file_mtime_set() API, implemented in unix and win32.

Patches from Branko Cibej (brane) and Matt Kraai <kraai@alumni.cmu.edu>.

* include/apr_file_io.h (apr_file_mtime_set):  declare.

* include/arch/win32/apr_arch_file_io.h:  expand apr_file_open
  internal flags;  add new APR_WRITEATTRS value.

* file_io/win32/open.c (apr_file_open): honor APR_WRITEATTRS flag.

* file_io/win32/filestat.c (apr_file_mtime_set):  implement in win32.

* file_io/unix/filestat.c (apr_file_mtime_set):  implement in unix.

* test/testfileinfo.c (test_mtime_set):  new API test.
