cpu/cc2538: rtt: implement rtt_get_alarm() 
We can't read back the alarm, so just store it in a variable.

cpu/cc2538: rtt: implement rtt_set_counter() 
We can't set the hardware counter directly, so always add an offset.

Move common code into helper functions and extract the commands
that differ between normal and RWWEE page reading / writing.
This cuts down on `#ifdef` use.

83a56ae666 cpu/sam0_common: merge RTC & RTT implementation 
The RTC and RTT share the same peripheral, so they can also
share the same code.

This is needed to integrate the Tamper Detection into common
RTC/RTT code.

2ed4486f21 cpu/esp32: cleanup of C++ hacks 
Since former ESP32 toolchain versions used POSIX threads, module `pthread` was required. The built-in `cxa_ctor_guards` had to be replaced since they used the `pthread_once` function for singleton objects initialization where the parameter `once` was of incompatible type with that provided by RIOT's `pthread` module. The current ESP32 toolchain version no longer uses POSIX threads. The dependency on module `pthread` as well as according C++ hacks can be removed.

e1f84de6c5 cpu/sam0_common: UART: simplify init sequence 
We don't need to read-modify-write the CTRLA register to disable
the UART.
The entire CTRLA register is re-written just a few lines below, so
we can just set it to 0 to disable the UART.

There is also no need to reset the UART since we re-write all config
registers in init.

cpu/stm32/periph_eth: Cleanup & fix DMA descriptor 
- Add missing `volatile` to DMA descriptor, as memory is also accessed by the
  DMA without knowledge of the compiler
- Dropped `__attribute__((packed))` from DMA descriptor
    - The DMA descriptor fields need to be aligned on word boundries to
      properly function
    - The compiler can now more efficiently access the fields (safes ~300 B ROM)
- Moved the DMA descriptor struct and the flags to `periph_cpu.h`
    - This allows Doxygen documentation being build for it
    - Those types and fields are needed for a future PTP implementation
- Renamed DMA descriptor flags
    - They now reflect to which field in the DMA descriptor they refer to, so
      that confusion is avoided
- Added documentation to the DMA descriptor and the corresponding flags

7269dc4e3a cpu/sam0_common: i2c: allow arbitrary I2C frequencies 
The Atmel I2C peripheral supports arbitrary I2C frequencies.
Since the `i2c_speed_t` enum just encodes the raw frequency values,
we can just use them in the peripheral definition.

We just have to remove the switch-case block that will generate an error
for values outside of `i2c_speed_t`.

cortexm_common: Clear PendSV request after idle sleep 
The PendSV interrupt is used to request a scheduling operation. An
interrupt during the idle sleep can re-request the PendSV interrupt,
while the PendSV is still busy scheduling the next thread. This clears
the request after sleep to prevent triggering an extra PendSV interrupt
after the current PendSV handler finished.

cortexm_common: disable IRQ during thread_sched_idle 
A race condition is present where an IRQ is serviced between the
priority increase of the PENDSV and the sleep. When the IRQ
is serviced before the WFI sleep, the core will sleep until the next
IRQ and the thread activated by the IRQ will not be scheduled until
a new IRQ triggers.

This commit wraps an IRQ disable and restore around the priority
modification and sleep to prevent interrupts from being serviced until
the WFI call returns.

cpu/stm32: Fix uart_init() 
- Make use of the fact that gpio_init_af() does not need prior call to
  gpio_init() for all STM32 families anymore and drop call to gpio_init()
- Initialize the UART periph first, before initializing the pins
    - While uninitialized, the UART periph will send signal LOW to TXD. This
      results in a start bit being picked up by the other side.
    - Instead, we do not connect the UART periph to the pins until it is
      initialized, so that the TXD level will already be HIGH when the pins
      are attached.
    - This results in no more garbage being send during initialization

cpu/stm32: Fix gpio_init() / gpio_int_af() 
- Do not set an intermediate mode, prepare correct mode settings in a temporary
  variable
- Consistently enabled the GPIO periph in gpio_init_af()
    - Previously, STM32 F1 did not require a separate call to gpio_init() prior
      to a call of gpio_init_af(), but other STM32 families did
    - Now, gpio_init_af() can be used without gpio_init() consistently
- STM32 F1: Do not touch ODR for non input pins
    - For input pins, this enables / disabled pull up resistors. For outputs,
      this register should remain untouched (according to API doc)

- Add libstdcpp feature to indicate a platform is providing a libstdc++

- The existing cpp feature now only indicates a working C++ toolchain without
  libstdc++. (E.g. still useful for the Arduino compatibility layer.)
- Added libstdcpp as required feature were needed
- Added some documentation on C++ on RIOT

cpu/cortexm_common: Drop LTO workaround for Cortex M thread_arch.c 
The `ldr    r1, =sched_active_thread` instruction couldn't be assembled with
LTO, as the no immediate offset could be found to construct the address of
`sched_active_thread`. This commit instructs the assembler to generate a
literate pool which can be used to construct the address. While this issue
was only triggered during LTO, it theoretically could also pop up without LTO
due to unrelated changes. Thus, it is a good idea to create the literate pool
even without LTO enabled.

0ddca68de9 cpu/fe310: use common names for heap markers 
Other archs use `_sheap` and `_eheap` to mark the start and end of
the heap.

fe310 uses `_heap_start` and `_heap_end`, so platform independent
code that wants to make use of this will needlessly fail.

For compatibility with common code, name them the same on fe310.

cpu/cortexm_common: Fix cpu_switch_context_exit() 
- Use `irq_enable()` over `bl irq_enable`, as `irq_enable()` is an inline
  function and not a C function any more
- Drop `__attribute__((naked))` qualifier
    - It must be used with the declaration of the function, but there it is
      missing. (And it cannot be added there, as this function would need to
      be implemented as "naked" by every platform; which is impossible for
      platforms not supporting `__attribute__((naked))`.)
    - Only functions consisting completely of basic asm may be marked as naked.
      But both the assembly used to trigger the SVC interrupt as well as the
      assembly used in `irq_enable()` are extended asm, not basic asm
- Use ` UNREACHABLE();` over a custom asm construct

- Updated to inline-able IRQ API
- Improved robustness of functions
    - Added memory barrier to prevent the compiler from moving code outside of
      a critical section guarded by irq_disable() ... irq_restore()
- Reduced overhead of `irq_disable()`
    - After clearing the global interrupt enable (GIE) bit, IRQs remain enabled
      for up to one CPU cycle
    - The previous implementation just added a nop to fill that cycle
    - This implementation uses the cycle for masking the return value
- Reduced overhead of `irq_restore()`
    - Now only one CPU cycle is needed
- `irq_disable()`, `irq_restore()`, and `irq_enable()` work now in constant time

kinetis/spi_scalar: Add local ARRAY_SIZE define 
The spi scalar calculation tool for the kinetis family is stand-alone
and doesn't use the RIOT headers. It doesn't include the ARRAY_SIZE
macro from the RIOT headers. This commit adds a local definition of the
ARRAY_SIZE macro

c0203ad35c cpu/sam0_common: GPIO default to MAIN clock for EXTI, make configurable 
Currently only samd21 used the 32 kHz clock for EXTI which makes it miss fast events.
All newer members of the family use the MAIN clock.

While touching this, also make the clock source configurable to this can be overwritten,
e.g. in the board config if desired.

cpu/sam0: avoid deadlock on nonblocking write 
If a write to a full tsrb is attempted with disabled interrupts
or in a interrupt then a deadlock will occure. To avoid this make
space in the ringbuffer by synchronously writing to uart.

585dc15f99 cpu/sam0_common: UART: implement inverted RX & TX 
The UART TX and TX lines on SAMD5x and SAML1x can be inverted.
However, the flags don't do exactly what one would expect.

See errata 2.18.5: SERCOM-UART: TXINV and RXINV Bits Reference:

> The TXINV and RXINV bits in the CTRLA register have inverted functionality.
>
> Workaround:
> In software interpret the TXINV bit as a functionality of RXINV, and conversely,
> interpret the RXINV bit as a functionality of TXINV.
