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.
* Rebaseline firmware to non-OS SDK version 3.0
* Note that SDK version 3.0 introduces the concept of a Flash Partition Table(PT). This is located at Flash offset 0x10000 in our firmware build.
* The firmware is now PT aware with both LFS and SPIFFS taking their partition size and location from the PT
* 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.
* I2C driver speed-up, i2c.SLOW, i2c.FAST and user-defined speed selection
* - Multiple buses (up to 10) with different speeds on each bus
- Standard(Slow, 100kHz), Fast(400kHz) and FastPlus(1MHz) modes or an
arbitrary clock speed
- Sharing SDA line over multiple I²C buses to save available pins
- GPIO16 pin can be used as SCL pin, but it does not support clock
stretching and selected bus will be limited to FAST speed.
* Dynamic memory allocation, error checks, simplification, timing tweaks.
* Separated the code of old driver for better compatibility and simplicity
* Change of driver interface
* Add bus status check in setup(); simplify getDC(); remove unnesessary lines in ACK read/write
* Fix for moved doc file and trailing whitespaces
* Fix some subtle timing issues with gpio.pulse
* Add the pulse:update method
* Allow getstate to work on stopped pulsers
* Make gpio.mode(, gpio.OUTPUT) actually set the output mode
* Added some more documentation
* Add support of counting of interrupts
* Update the timestamp when interrupt happens during dispatch. Also
clear out interrupts when setting up a new callback
* Check the return code of the read function when doing crypto.fhash so that we don't pass negative lengths to the hashing functions
* Fix various assert failures in the LVM arising from rotables. No functional change
* Add the gpio interrupt time to the callback (and pass it from the interrupt handler)
* Get the PC right in the perf module
* Make the headers static in the websocket module
* Fix the documentation
* Add FatFs
* enable BUILD_FATFS for all-module build
* push vfs into rest of firmware
* align maximum filename length
* increase timeout for acmd41 during card initialization
* switch from DOS to Unix path semantics chdrive() is substituted by chdir()
* update to fatfs R.012a incl. patches 1-6
* add callback for rtc provisioning in file
* update docs

As with the last commit this rolls up the follwowing, but include the various
review comments on the PR.
- **Documentation changes**. I've added the taks FAQ as a stub new Extension
developer FAQ, and split the old FAQ into a Lua Developer FAQ and a Hardware
FAQ.
- **Tasking I/F**. New `app/task/Makefile`, `app/task/task.c`,
`app/include/task/task.h` and `app/Makefile` as per previous commit. Cascade
changes to `app/driver/uart.c`, `app/include/driver/uart.h`,
`app/user/user_main.c` and `app/modules/node.c`
- **GPIO Rework** to `app/modules/gpio.c` and `pin_map.[hc]`, `platform.[hc]`
in `app/platform`
- **Other Optimisations** Move the `platform_*_exists()` from
`app/platform/common.c` to static inline declarations in `platform.h` as
this generates faster, smaller code. Move lgc.a routines out of iram0.
There was only one genuine use of this macro, all other places were
using it only as a necessary compensation. While this was fine as long as
it was the first meg of flash which was mapped, it became incorrect and
quite dangerous whenever this assumption did not hold (such as when
running from the second slot in an OTA scenario).
The flash API now uses actual addresses, not translated/mapped
addresses, and the users of this API have been adjusted accordingly.
This makes the flash API work correctly regardless of what flash mapping
is in use.
The old macro is still available under the new name
INTERNAL_FLASH_MAPPED_ADDRESS, and this is used to detect flash writes
where the source is mapped flash (and thus has to be bounced), and to
adjust the _flash_used_end linker symbol when used with
flassh_find_sector() by the filesystem code. The latter usage is not
OTA-proof, but in an OTA scenario the filesystem needs a fixed location
anyway and thus would not use this code path.
With the new SDK soft-wdt it is no longer sufficient to tickle the hardware
watchdog, so all (found) instances have been changed to system_soft_wdt_feed().
