Well, this molstly be about xxx_load_config function, with function type changed.
The new load_config function will return 1 if failed, or 0 if successed.

Removes the core/include/dir.h, and put the dir structures to sys/dirent.h to
avoid the compile error.

We fist make it simple, as told by hpa. Here're the changes:
1, The DIR structure changed, just a file pointer included.
2. So, the open/close/read-dir stuff in com32/lib/ changed again.
3. We read one stuff from every readdir call.

Here're some big changes:
1. The vfs-dir stuff added.
2. The dir-functions in com32/lib are mostly rewritten.
3. with little change on rosh for avoid the compile error

Well, I don't think it's a good vfs-dir interface.

We can use stpcpy() as generic_unmangle_name(); this also gives us the
pointer to the end that the assembly code wants and expects.

FILENAME_MAX was 2^8 in all variants by now; make it a common define.
Libraries mangle/unmangle; we have generic_mangle_name for Unix-like
filesystems, and unmangle now defaults to simple strcpy.

Major cleanups to the VFS layer:
- add a persistent generic "struct file"
- pass "struct file *" to getfssec
- add a close_file method
- use VFS-assigned indicies instead of pointers as file handles.
  This allows the file structures to be allocated from high memory.
