uninitialized buffer in midnight commander

["Ilya Teterin" <alienhard@xxxxxxx>]

Midnight Commander is using uninitialized buffer for handling symlinks in VFS 
(tar, cpio). See vfs/direntry.c, handling of buf[] at vfs_s_resolve_symlink(). 
I wonder but it works almost properly ;-)

On linux-i386 I can reach stack buffer overflow using specially crafted 
archive. Open http://buggzy.narod.ru/exp.tgz in mc's VFS to test (mc will 
crash).

Affected systems/vendors/archs: at least linux-i386, mc-4.5.52 to mc-4.6.0, too 
lazy to test others ;-)

P.S. Greetings to iDEFENSE VCP. I'm tired and hungry ;)
