Johny Mattsson e49f2bb13f Remove conflicting libc, rename c_xx and os_xx to xx.
c_strtod and c_getenv are kept since strtod doesn't appear in the SDK's libc,
and we want our own c_getenv to initialize the Lua main anyway.

Johny Mattsson f3e2a3afd9 Initial pass at switching to RTOS SDK.
This compiles, links, and starts the RTOS without crashing and burning.

Lua environment does not yet start due to the different task architecture.

Known pain points:

  - task implementation needs to be rewritten for RTOS (next up on my TODO)

  - secure espconn does not exist, all secure espconn stuff has been #if 0'd

  - lwip now built from within the RTOS SDK, but does not appear to include
    MDNS support. Investigation needed.

  - there is no access to FRC1 NMI, not sure if we ever actually used that
    however. Also #if 0'd out for now.

  - new timing constraints introduced by the RTOS, all use of ets_delay_us()
    and os_delay_us() needs to be reviewed (the tsl2561 driver in particular).

  - even more confusion with ets_ vs os_ vs c_ vs non-prefixed versions.
    In the long run everything should be switched to non-prefixed versions.

  - system_set_os_print() not available, needs to be reimplemented

  - all the RTOS rodata is loaded into RAM, as it apparently uses some
    constants while the flash isn't mapped, so our exception handler can't
    work its magic. This should be narrowed down to the minimum possible
    at some point.

  - with each task having its own stack in RTOS, we probably need change
    flash-page buffers from the stack to the heap in a bunch of places.
    A single, shared, page buffer *might* be possible if we limit ourselves
    to running NodeMCU in a single task.

  - there's a ton of junk in the sdk-overrides now; over time the core code
    should be updated to not need those shims

Philip Gladstone f0c1034308 Send a multicast response for QM query and other mDNS fixes
* Send a multicast response if it is a QM query
* Use the NSEC record in the style which mDNS demands
* Shuffle the code a bit and allow sending of A response...
* Made the A record work
* Now gets TTLs right and (I think) handles multiple questions

Philip Gladstone 3a5e5f10e2 Take 2: Add regular sends to mdns. Check for (some) buffer overflows. Make it handle unicast
Merging as suggested by @TerryE (and squashing at the same time. Turns out that this feature is enabled for this repo).

* Squashed commit of the following:
