Just for readability reasons; to prevent overlooking deadline stuff
across over platforms.

Closes the API documentation gap between platforms.
Also makes the code textual representation same between platforms.

syscall: Use NewError for all system errors and introduce
some new errors for compatibility with other packages
and proper error handling in net. Also introduce
Temporary and Timeout methods on ErrorString.
net: Make errors from dial, accept, listen functions follow the
OpError standard and discern whether the underlying
error came from syscall. Since Plan 9 uses a correspondence
between file and network operations, all system error
reporting happens through the underlying file operation.
In Go code, we go through package os for file operations,
so there is another level of indirection in error types.
This change allows us to compare the errors with those in
package syscall, when appropriate.
os: Just use the error string already present in package os,
instead of calling out to package syscall.

Functions for representing network connections as files
and vice versa, on Plan 9.
Representing network connections as files is not so
straight-forward, because a network connection on Plan 9
is represented by a host of files rather than a single
file descriptor (as is the case on UNIX). We use the
type system to distinguish between listeners and
connections, returning the control file in the former
case and the data file in the latter case.

The data file should be opened when a Conn is first
established, rather than waiting for the first Read or
Write.
Upon Close, we now make sure to try to close both, the
ctl as well as data files and set both to nil, even in
the face of errors, instead of returning early.
The Accept call was not setting the remote address
of the connection properly. Now, we read the correct
file.
Make functions that establish Conn use newTCPConn
or newUDPConn.

When a nil listener address is passed to some protocol specific
listen function, it will create an unnamed, unbound socket because
of the nil listener address. Other listener functions may return
invalid address error.
This CL allows to pass a nil listener address to all protocol
specific listen functions to fix above inconsistency. Also make it
possible to return a proper local socket address in case of a nil
listner address.

The set of errors forwarded by the os package varied with system and
was therefore non-portable.
Three helpers added for portable error checking: IsExist, IsNotExist, and IsPermission.
One or two more may need to come, but let's keep the set very small to discourage
thinking about errors that way.

All tests enabled by default passes except those in timeout_test.go.
For TestLookupPort, add an entry for "bootps" in /lib/ndb/common
(Plan 9 calls it "bootp"). I've sent out a patch to fix this.
