Better handling of socket close. The 'closeRef' needed
its own environment to make if work in both cases (both
called and scheduled).
Also Introduced the enif select wrapper functions (read,
write, stop and cancel). Also add error handling at every
time one of these functions are called.

Another broken anchor fixed. The type 'ipv6_pktinfo' was
not exported nor was it part of the doc.

Add the 'depricated' attribute for the old (and decrepit)
functions from the old net module.

Corrected linking references (links) to functions.
Also added links from getopt/setopt functions to
the users guide.
Also added some comments to the socket module regarding
open with (ready made) descriptor (which is not yet
supported).

bmk/20190204/socket_as_nif/OTP-14831
|

The nif callback functions (nif_open) now instead cause an
'nosup' exception if called (instead of badarg).
The basic type uint16_t, uint32_t and int32_t (C99) replaced
"own" (that is, defined by "us") types Uint16, Uint32 and
Sint32.
The point of this is that our Windows build system seems to
be a bit lacking when it comes to types...
Removed "some stuff" that was if-defed. Different solution
when win32 support for sockets has been improved.
Make sure the socket_*.c util modules are not included
in the building for windows.

Its now possible to set a rcvbuf (otp) option value
of {N :: pos_integer(), BufSz :: pos_integer()}.
This value is used for type stream and protocol tcp,
when calling the function recv with length = 0 (zero).
The second value, BufSz, is the actual size of the receive
buffer used when calling the socket recv function, and
the first value, N, is the max number of possible reads
that will be performed (at most), even if there is more
data to read. This is limit the effect of DoS attacks.

Add a way to *get* the file descriptor (fd) of a socket.
Useful mostly for debugging.

Previously the "message interface" between the functions in
socket.erl and the nif-code (socket_nif.c) was "ad hoc".
This has now been changed so that we have a unified message
{'$socket', SockRef | undefined, Tag, Info}
This also has the added advantage of preparing the code for
when we start using the new select-fucntions (with which
its possible to specify your own message). This will be used
in order to get around our eterm "leak" (we will use a simple
counter, maintained in the nif, instead of the [Recv|Send|Acc]Ref
we generate in the erlang code today.

Closing files in these callbacks could block scheduler progress
and cause major system instability. We now defer these operations
to a dedicated process instead.
This process may in turn block forever and prevent further orphaned
files from being closed, but it will keep the emulator itself from
misbehaving.

Persistent terms are useful for storing Erlang terms that are never
or infrequently updated. They have the following advantages:
* Constant time access. A persistent term is not copied when it is
looked up. The constant factor is lower than for ETS, and no locks
are taken when looking up a term.
* Persistent terms are not copied in garbage collections.
* There is only ever one copy of a persistent term (until it is
deleted). That makes them useful for storing configuration data
that needs to be easily accessible by all processes.
Persistent terms have the following drawbacks:
* Updates are expensive. The hash table holding the keys for the
persistent terms are updated whenever a persistent term is added,
updated or deleted.
* Updating or deleting a persistent term triggers a "global GC", which
will schedule a heap scan of all processes to search the heap of all
processes for the deleted term. If a process still holds a reference
to the deleted term, the process will be garbage collected and the
term copied to the heap of the process. This global GC can make the
system less responsive for some time.
Three BIFs (implemented in C in the emulator) is the entire
interface to the persistent term functionality:
* put(Key, Value) to store a persistent term.
* get(Key) to look up a persistent term.
* erase(Key) to delete a persistent term.
There are also two additional BIFs to obtain information about
persistent terms:
* info() to return a map with information about persistent terms.
* get() to return a list of a {Key,Value} tuples for all persistent
terms. (The values are not copied.)

The sendmsg function attempts to send *one message*. But
its possible for the underlying software to fail to send
the *entire* message. So, instead of retrying itself, as
send does, the sendmsg function will now instead return
with {ok, Remaining}, leaving it to the caller to decide
what to do.

The send and recv test case triggered a two bugs. One was
that there was no re-selecting when only a portion of the data
was received (which meant that we stopped reading).
Also, the wrong 'current' (writer) was reset when demonitor
current reader after a successful read (which meant that
future readers would never have been monitored).
