- commit of wip prior to rebaselining against current dev
- more tweaks
* #2954: adapt to the new firmware api for the timer and some other small fixes
* reduce the error msg in when not response is sent back from esp
* cleanup: remove trailing whitespaces

* BMP085 pressure sensor: fix temperature value data type
the data type for t (U_T) should be long according to the BMP085
datasheet (rev. 1.2, section 3.5). values over 32767 can indeed occur,
and in my case lead to a wrong value for the temperature (and
consequently also pressure).
note: this problem only occurs above a certain temperature (exact
value depends on the calibration, but I assume somewhere around 26°C).
* BMP085 pressure sensor: adapt data types and calculation
this adapts the data types and calculation to be consistent with the
datasheet (rev. 1.2, section 3.5). while I did not notice any issues,
using the wrong data types could trigger edge cases.
Because the old API was inactive, we were setting
MBEDTLS_SSL_VERIFY_NONE even after we'd parsed the certificate.
tls tests now include a deliberate certificate mismatch; this was
discovered by moving the mqtt tests over to the new API.
Removes yet another unchecked allocation point in our C libraries.
While here, fix potential reference leaks on error paths
Also while here, remove some stale documentation. There can be as many
DNS requests in flight as LwIP has room for in its table
(DNS_TABLE_SIZE, which defaults to 4).
* 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
* 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.
Here `conn` is net.socket instance, so it should be called as one.
Otherwise request is very likely to end up with crash and PANIC.
