open.2: Remove accidental mention of O_TTY_INIT
...
An earlier edit mentioned O_TTY_INIT as a file creation flag.
That's true, according POSIX, but Linux does not implement
this flag, so remove mention of it.

link.2, open.2: Update AT_EMPTY_PATH and O_PATH documentation
...
The current text reflects the general worry in the kernel about
recipients of O_PATH fds being able to hardlink the referenced
files. It turns out that it was possible to link these files
regardless of any possible security concerns.
Linux 3.11 removes the capability check in AT_EMPTY_PATH.
I expect that this functionality will be generally useful,
so let's document it better.

The sentence in open(2) man page in notes for O_DIRECT flag:
"Under Linux 2.6, alignment to 512-byte boundaries suffices."
is not universally correct. The alignment is a property of the
storage, for example, 4k-sector drives with no 512 byte sector
emulation will be unable to perform 512-byte direct I/O.
The patch clarifies this sentence.
