Store adddress in the memory immediately preceding the packet data.
It is guaranteed to have enough space (IP header is 20 bytes).
Introduce a limit on the length of the RX chain,
MG_LWIP_MAX_UDP_RX_CHAIN_LEN. Default is 20.
This is required to distinguish input interface for multicast traffic
and select correct output interface for outgoing traffic (advertisements).
http://savannah.nongnu.org/bugs/?49662 removed ability to receive
multicast traffic on on interface-bound sockets (making the previous
change useless, hence the revert), so for LWIP 2.0.1 and newer
multicast packets can only be received on INADDR_ANY listeners.
User is then required to distinguish input interface in the receive path.
This information is only available in the udp_recv callback, so we must
pass this down to dns-sd library somehow, and priv_2 is the how.
It is normally used for DNS resolver state, and is never used on
listening sockets. We thus avoid growing the mg_connection structure.
* Do not set MG_F_SSL ona connection until it's been fully accepted (MG_SIG_ACCEPT is handled).
This fixes a crash when SSL connection is polled before it's fully initialized.
* Fix mg_lwip_tcp_error_cb to NULL out tcp_pcb pointer even if mg_connection is already shutting down.
After mg_lwip_tcp_error_cb, tcp_pcb pointer can no longer be used and doesn't need to be freed.
This fixes https://github.com/cesanta/mongoose-os/issues/545
ESP8266 non-OS has very limited stack - only 4K. Undetected stack
overflows cause nasty bugs and it turns out serving files over http
routinely causes stack overflow.
This was exposed by https://github.com/cesanta/mongoose-os/commit/a5f59123edcfef10c351b3e679f28720b5de9611
As a short-term workaround, push http_message into bss, this is enough
as an immediate workaround. Longer term, we need to think how to bring
8266 to parity with other platforms where we have at least 8K stack.
At the same time, get rid of the compiler bug workaround - modern
toolchain doesn't need this.
Now src contains exactly what's embedded in mongoose.c and .h, nothing more.
Added `tools/amalgam.sh` to aamlgamate both files at once.
There are no functional changes to mongoose.c, .h in this PR, only slight filename changes.
* Actually drop the connection when no response to ping arrives within the next interval.
* Avoid sending immediate ping when wall time is adjusted, it's usually spurious.

If file ends with .gz and has known "secondary extnesion", i.e. test.html.gz,
its content type is determined by the secondary extension and content-encoding is set to gzip.

Check response code, make sure it's 101.
Pass http_message to the client to keep it appraised.
This represents a slight change in the API -
in case of an error MG_EV_WEBSOCKET_HANDSHAKE_DONE will now be delivered where previosuly connection would just hang.
Clients that do not examine the argument may for a moment think handshake has succeeded but in fact connection will be closed immediately.

cs_log_set_filter() is removed in favor of cs_log_set_file_level() which
allows setting log verbosity of individual files and/or lines.
E.g.: `mg_=1,mjs=1,=4` - level for for everything except mjs and mongoose.
We use the fact that we are usually pretty careful with our file names and use prefixes consistently.
In mos, `debug.file_level` sets the option on boot and `Sys.SetDebug` is updated to parse `file_level` option to change it at runtime.
CL: Log file:line instead of function; add cs_log_set_file_level()
