A few variables in `lib/dgram.js` are redeclared with `var` in a scope
where they have already been declared. These instances can be scoped
more narrowly with `const`, so that's what this change does.

Modifies the dgram send() method to not emit errors when a DNS
lookup fails if there is a callback. Given that the same UDP
socket can be used to send messages to different hosts, the socket
can be reused even if one of those send() fails.
This slightly changes the behavior of a stable API, so that it behaves
as users would expect to.
This is based on https://github.com/joyent/node/pull/7738, which
landed in 77266d7fadd8dfefb107ccb1e3fe97f9620f1288.

This commit better handles calls to process.binding() in lib/ by
no longer lazy loading the bindings (the load times themselves are
rather miniscule compared to the load time of V8) and never reloading
the bindings (which is 172 times slower than referencing a variable with
the same value).

Server sockets should be shared by default, and client sockets should be
exclusive by default. For net/TCP, this is how it is, for dgram/UDP, its
a little less clear what a client socket is, but a socket that is
auto-bound during a dgram.send() is not usefully shared among cluster
workers, any more than an outgoing TCP connection would be usefully
shared.
Since implicit binds become exclusive, implicit/client dgram sockets can
now be used with cluster on Windows. Before, neither explicit nor
implicitly bound sockets could be used, causing dgram to be completely
unsupported with cluster on Windows. After this change, they become half
supported.

Add range checks for the offset, length and port arguments to
dgram.Socket#send(). Fixes the following assertion:
node: ../../src/udp_wrap.cc:264: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`offset < Buffer::Length(buffer_obj)' failed.
And:
node: ../../src/udp_wrap.cc:265: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`length <= Buffer::Length(buffer_obj) - offset' failed.
Interestingly enough, a negative port number was accepted until now but
silently ignored. (In other words, it would send the datagram to a
random port.)
This commit exposed a bug in the simple/test-dgram-close test which
has also been fixed.
This is a back-port of commit 41ec6d0 from the master branch.
Fixes#6025.
Don't use v8::Object::SetHiddenValue() to keep a reference alive to the
buffer, we can just as easily do that from JS land and it's a lot faster
to boot.
Because the buffer is now a visible property of the write request
object, it's essential that we do *not* log it - we'd be effectively
serializing the whole buffer to a pretty-printed string.
v0.10 allows strings for the offset, length and port arguments to
dgram.send() and dgram.sendto() but master before this commit would
abort with the following assert:
node: ../../src/udp_wrap.cc:227: static void
node::UDPWrap::DoSend(const v8::FunctionCallbackInfo<v8::Value>&,
int): Assertion `args[2]->IsUint32()' failed.
Go beyond what v0.10 does and also add range checks: offset and length
should be >= 0, port should be between 1 and 65535.
That particular change needs to be back-ported to v0.10 because passing
a negative offset or length number aborts with the following assertions:
node: ../../src/udp_wrap.cc:264: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`offset < Buffer::Length(buffer_obj)' failed.
Or:
node: ../../src/udp_wrap.cc:265: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`length <= Buffer::Length(buffer_obj) - offset' failed.
Interestingly enough, a negative port number is accepted in v0.10 but
is silently ignored.
This commit exposed a bug in the simple/test-dgram-close test which
has also been fixed.
Passing the number of sent bytes to the callback is superfluous;
datagram sockets operate in atomic mode: either the sendmsg() system
call succeeds or it fails but it never does partial writes.
Instead, report send errors to the callback. UDP error reporting is
fairly haphazard on most platforms. You should not expect reliable
delivery of anything besides EMSGSIZE and (possibly) ENETDOWN and
ENETUNREACH.
Fixes#2608.
Libuv now returns errors directly. Make everything in src/ and lib/
follow suit.
The changes to lib/ are not strictly necessary but they remove the need
for the abominations that are process._errno and node::SetErrno().
