Fix info leaks.

Fix stupid bugs in linux_sys_shmctl(): the index could be out of bound
(page fault) and there was no proper locking.
Maybe we should just remove LINUX_SHM_STAT, like compat_linux32.

Remove printf.

When dealing with an unknown value, set -1, to prevent (harmless)
uninitialized accesses later.

Add a default case, don't call sys_ioctl() with an uninitialized 'com'
argument.

Fix error handling, returns an errno, not -1.

Put the printf under DEBUG_LINUX.

Hum, don't forget the 'pid' argument, otherwise we're not gonna go very
far.

Don't read data from userland directly. This simply does not work on any
recent x86 CPU (thanks to SMAP) and all architectures that forbid direct
access to userland from the kernel. But I guess no one noticed because no
one ever uses compat_linux, right?

Hum, don't pass an mbuf to realloc(). Inspired from copyin32_msg_control().

Fix memory leak.

I don't see the point in having this useless printf, but add a '\n' to it,
so that it at least displays useless stuff correctly.

Hum, remove incorrect assignment. Userland could have passed a smaller
namelen, and the uninitialized bytes from sb_data were being used later in
the network stack.
