Michael Kerrisk 86426e0be4 accept.2, read.2, recv.2, send.2, write.2: Fix discussion of EAGAIN/EWOULDBLOCK errors 
For a non-blocking socket, POSIX.1-2001/2008 allow either
EAGAIN or EWOULDBLOCK to be returned in cases where a call
would have blocked.  Although these constants are defined
with the same value on most Linux architectures (PA-RISC
is the exception), POSIX.1 does not require them to have
the same value.  Therefore, a portable application using
the sockets API should test for both errors when checking
this case.

(NB POSIX.1 only mentions EWOULDBLOCK in the context of
the sockets interfaces.)

Change made after a note cross-posted on linux-arch@vger,
http://thread.gmane.org/gmane.linux.debian.ports.hppa/5615
and a suggestion for write(2) from Carlos O'Donell

Michael Kerrisk fecaa19a28 accept.2: Reorder ERRORS list 
Some errors were listed under a separate "may" heading.
There's probably no real need to do this; integrate
those errors into the main list.

Michael Kerrisk b98353f035 accept.2: Clarify details when returned address is truncated 
If the returned address is truncated, the 'addrlen' argument
indicates the actual size of the address, rather than a count
of the number of bytes in the truncated buffer.

Also clarify that if 'addr' argument is NULL, then 'addrlen'
should is unused, and should also be NULL.
