[Box Backup] Patch for raidfile test on NetBSD 4/5

[Jose Luis Rodriguez Garcia]

1- I have created a patch for raidfile test. I copy the patch at the
end of the email.

If I must create a trac ticket, please create a account trac. Login: joseyluis

With this patch NetBSD pass the raidfile test. I have tested it on NetBSD 4.

The problem is that in NetBSD 4/5 the readdir and openddir functions
are called in libc: __readdir30 and __closedir30.
readdir and closedir exist for compatibility with NetBSD 3 and before.

There was a change in the ABI between the 3 and 4 version for enable
64 bits types.

2- What is the purpose of intercept these function calls in the
intercept.cpp file?
