Fail CI build on warnings
This allows developers to add CFLAGS for -Wno-error=XXX while developing, but before code passes the CI build then it must be warning-free.

newlib: add "full" formatting support
This change adds support for 64-bit formats and C99 features to newlib printf/scanf functions. This support is enabled by default in menuconfig, but can be switched off to reduce code size.
Also adds missing functions such as fmod and fmodf.
- Fixes https://github.com/espressif/esp-idf/issues/52
- Fixes https://github.com/espressif/esp-idf/issues/83
See merge request !274
- add two versions of libc: libc.a and libc_nano.a. First one has full C99 formatting support, second one uses “nano” formatting functions available in ROM.
- fix linker error for fmod, fmodf, atof, atoff
- update tests
UART console selection
This change adds a set of menuconfig options to set custom UART#, baud rate, and pins, for console output.
Ref. TW8146
Also includes the following changes:
- `uart_tx_wait_idle`: fix issue with last character not transmitted. ROM function `uart_tx_wait_idle` may have a bug which causes the function to return before the final character is fully transmitted. This replaces `uart_tx_wait_idle` declaration with a static inline definition which fixes the issue. Also replaces the use of `uart_tx_flush` with `uart_tx_wait_idle` in `esp_restart`, to remove garbage in console output on restart.
- `rtc_printf` is temporary replaced with a no-op, pending a new release of librtc.a. Current release assumes that UART0 is used for output,
and switches UART0 baud rate while doing frequency changes and printing some log output. This doesn’t work if a different UART is used for output.
- disable boot watchdog only after starting the main task. Boot watchdogs were disabled very early in startup code. It was possible to introduce an infinite loop anywhere in the many functions called from startup code, and this would not be detected by interrupt watchdog and task watchdog. This change postpones disabling of boot watchdogs to the point when the scheduler is running. Also replaces register expressed using integer address with a name. This change is not directly related to the previous ones, but was found while debugging UART selection features.

Removal of spurious newline character in debug statement
There was a debug statement in the code that included an additional newline character that wasn't needed.
From github PR: https://github.com/espressif/esp-idf/pull/124
See merge request !291
On Xtensa windowed ABI backtrace is easy to do, and it's immensely
useful for debugging, so - do it by default.
We try to be careful and not deref bogus pointers while walking the
frames.
Example output (from debugging espressif/esp-idf#133):
Backtrace: 0x1:0x3ffc51e0 0x400e9dfa:0x3ffc5210 0x400e9ebc:0x3ffc5230 0x400ec487:0x3ffc5260
With just addr2line utility from binutils, this already pinpoints the
location of the crash.

Setting happens in bootloader startup code for PRO CPU, and in application startup code for APP CPU.

Driver: add rtc module
1. add rtc io control API (pull,output and input)
2. add touch pad API (touch pad read and interrupt)
3. add adc1 API (the max width is 12 Bits and support attenuation)
4. add hall sensor API (support hall sensor read )
5. add dac API (the width is 8 Bits)
See merge request !243

bugfix(gpio):gpio32 and gpio33 can not output and input
the gpio32 and gpio33 is initialize by librtc.a,and gpio_config not initialize the gpio as
digital gpio.they can not output and input,when users use gpio32 or gpio33.And there are some problems
about others driver ,when they use gpio32 or gpio33 as matrix.
Function name and error string are usually sufficient to find the place which has triggered an error. __FILE__ macro generates a string which has absolute file name (with our build system), so there is a lot of long strings present in the program because of that.

Small debugging fixes
Invoke panic handler when a stack overflow has been detected; unhandled interrupt handler now prints interrupt/cpu number for easier pinning down of source.

unit-test-app: Don't auto-display menu after test run finishes
Previous code would sometimes display menu multiple times, depending on UART activity.

Gdbstub: Fix bug, small cleanup
Tianzhongxing found a small bug preventing gdbstub to work in certain cases. This fixes it, as well as including some minor cleanups.
