Nathaniel Wesley Filardo af426d0315 Networking rampage and accumulated fixes (#3060)
* espconn: remove unused espconn code, take 1

This is the easiest part of https://github.com/nodemcu/nodemcu-firmware/issues/3004 .
It removes a bunch of functions that were never called in our tree.

* espconn: De-orbit espconn_gethostbyname

Further work on https://github.com/nodemcu/nodemcu-firmware/issues/3004

While here, remove `mqtt`'s charming DNS-retry logic (which is neither
shared with nor duplicated in other modules) and update its :connect()
return value behavior and documentation.

* espconn: remove scary global pktinfo

A write-only global!  How about that.

* net: remove deprecated methods

All the TLS stuff moved over there a long time ago, and
net_createUDPSocket should just do what it says on the tin.

* espconn_secure: remove ESPCONN_SERVER support

We can barely function as a TLS client; being a TLS server seems like a
real stretch.  This code was never called from Lua anyway.

* espconn_secure: more code removal

* espconn_secure: simplify ssl options structure

There is nothing "ssl_packet" about this structure.  Get rid of the
terrifying "pbuffer" pointer.

Squash two structure types together and eliminate an unused field.

* espconn_secure: refactor mbedtls_msg_info_load

Split out espconn_mbedtls_parse, which we can use as part of our effort
towards addressing https://github.com/nodemcu/nodemcu-firmware/issues/3032

* espconn_secure: introduce TLS cert/key callbacks

The new feature part of https://github.com/nodemcu/nodemcu-firmware/issues/3032
Subsequent work will remove the old mechanism.

* tls: add deprecation warnings

* luacheck: net.ifinfo is a thing now

* tls: remove use of espconn->reverse

* mqtt: stop using espconn->reverse

Instead, just place the espconn structure itself at the top of the user
data.  This enlarges the structure somewhat but removes one more layer
of dynamic heap usage and NULL checks.

While here, simplify the code a bit.

* mqtt: remove redundant pointer to connect_info

Everywhere we have the mqtt_state_t we also have the lmqtt_userdata.

* mqtt: doc fixes

* mqtt: note bug

* tls: allow :on(...,nil) to unregister a callback

Nathaniel Wesley Filardo 30f706fb03 WIP: MQTT fixes (#2986)
* mqtt: expose "connfail" callback via :on()

This makes it just like all the other callbacks in the module and is a
revision of behavior called out in
https://github.com/nodemcu/nodemcu-firmware/pull/2967

* mqtt: clarify when puback callback fires

* mqtt: Don't reference stack buffers from the heap

The confusingly-named "mqtt_connection_t" object is just a triple of
  - a serialized mqtt message pointer and length
  - a buffer pointer (to which the above can be written)
  - a message identifier

The last of these must be passed around the mqtt state machine, but the
first two are very local and the buffer is always sourced from the C
stack.  Unfortunately, because the entire structure is persisted in the
heap, some callers assume that they can always use the structure without
reinitialization (see mqtt_socket_close), which will trash the C stack.

Sever the pairing between message id and local state, punt the local
state entirely out of the heap, and rename things to be less confusing.

Nathaniel Wesley Filardo 948325a996 New `net.if.info` call to show LwIP information (#2862)
* Remove app/include/netif/wlan_lwip_if.h

This file appears to be unused in our tree.

* New `net.if.info` call to show LwIP information

This is a generalization of `wifi.sta`'s and `wifi.ap`'s `getip` and
`getmac` calls.  I don't propose to deprecate those, but perhaps we
should, in the documentation, point users at this function instead.

The direct motivation is to permit continued use of DHCP-provided NTP
servers in a future where
https://github.com/nodemcu/nodemcu-firmware/pull/2819 has landed, now
that https://github.com/nodemcu/nodemcu-firmware/pull/2709 is in the
tree.  But rather than exposing just that information, a more general
interface seems useful.

Nathaniel Wesley Filardo 282ebd100d Deprecate crypto.to{Hex,Base64} (#2929)
The internal implementation already preferentially forwards to the
encoder module, so we should just remove these functions as they confuse
people into thinking that we don't have their inverses (see the feature
request https://github.com/nodemcu/nodemcu-firmware/issues/2907).

Update the docs to refer to the encoder version and add deprecation
warnings to the runtime implementations.

Nathaniel Wesley Filardo 7d387dd4d6 Simplify and tidy SNTP (#2700)
* list_ref can become LUA_REFNIL, because that's what rawgeti returns
  for LUA_NOREF.  Defensively guard for this, rather than falling into
  the sntp_dolookups loop with nil on the stack.

* set_repeat_mode should not call itself, but should rather always do
  what it's going to do and then optionally do the rest if directed.

* sntp_sync should not try to special case the single string argument:
  we should be queueing that name for DNS resolution, too.  Towards that
  end, if we are given a single string, build a table and make that the
  list_ref and call off to sntp_dolookups, just like we otherwise do.

Johny Mattsson 526d21dab4 Major cleanup - c_whatever is finally history. (#2838)
The PR removed the bulk of non-newlib headers from the NodeMCU source base.  
app/libc has now been cut down to the bare minimum overrides to shadow the 
corresponding functions in the SDK's libc. The old c_xyz.h headerfiles have been 
nuked in favour of the standard <xyz.h> headers, with a few exceptions over in 
sdk-overrides. Again, shipping a libc.a without headers is a terrible thing to do. We're 
still living on a prayer that libc was configured the same was as a default-configured
xtensa gcc toolchain assumes it is. That part I cannot do anything about, unfortunately, 
but it's no worse than it has been before.

This enables our source files to compile successfully using the standard header files, 
and use the typical malloc()/calloc()/realloc()/free(), the strwhatever()s and 
memwhatever()s. These end up, through macro and linker magic, mapped to the 
appropriate SDK or ROM functions.

* A new tool `tools/nodemcu-partition.py` is now used to initialise these data and can also download LFS and SPIFFS images to these partitions.

stretching and selected bus will be limited to FAST speed.

	Do not enable the largest ECs for computational time
	Do not enable 25519 (sad) because it doesn't go across the wire
Drop non-PFS key exchanges

Drop renegotiation support completely
	It takes so much heap that it's not likely to work out well

Tidy handling of SSL_BUFFER_SIZE

Update docs
Drop mention of startcom, since they are no more, for letsencrypt

* Update mbedtls to 2.7.7

Preserve our vsnprintf and platform hacks

* Introduce TLS maximum fragment size knob

Reduce buffer size to 4Ki by default and advertize that.  That's the
largest we can advertize with the TLS MFL extension, so there's no
point in making them larger.  The truly adventurous can re-raise
SSL_BUFFER_SIZE and undefine the SSL_MAX_FRAGMENT_LENGTH_CODE and get
back to the earlier behavior.

* MQTT: handle large/chunked/fragmented messages properly

If a message spans multiple TCP packets it must be buffered before
delivered to LUA. Prior code did not do this at all, so this "patch"
really adds proper handling of fragmented MQTT packets.
This could also occur if multiple small messages was sent in a
single TCP packet, and the last message did not completely fit in that
packet.

Introduces a new option to the mqtt.Client constructor:
max_publish_length which defaults to 1024

Introduces a new 'overflow' callback.

Fixes issue #2308 and proper fix for PR #2544.

* mqtt.md: clarified heap allocation

* mqtt: ensure ack is sent for overflowed publish

If QoS is used we should still acknowledge that we received it, or server might retransmit it later.

-  Optimise ROTable accesses and interface

This includes some refinements to the ROTable cache which remove the linker cludges on the CROSS_COMPILE builds.  Also keyhole tweaks to some of the Lua VM code to implrove runtimes.

I also noticed some compile time warnings during the build; the change to uz_unzip.c doesn't impact the compiled code, but does remove the compiler warnings.

Johny Mattsson 085f35da73 Tie in the EGC with the SDK's heap knowledge. (#2319)
Added `node.egc.meminfo()` to expose LVM usage (to make the regular
`node.egc.ON_MEM_LIMIT` option usable).

Extended the `node.egc.ON_MEM_LIMIT` option to also take negative limits,
in which case that's taken as a request to keep a certain amount of heap
available for non-Lua use.

fix for ds18b20 negative decimals
ds18b20 decimals do not take into account the sign bit. Since the original calculation was not so readable, rewritten in readable way that also fixes the bug. Same code as PR against master.
