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.

We don't need to read-modify-write the CTRLA register to disable

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.

- 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

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: fix bit-banding check
...
Not all MCUs ≥ Cortex-M3 provide the Bit-Banding feature.
It is up to the manufacturer to implement it.
Instead, rely on the CPU_HAS_BITBAND being set in `periph_cpu.h`.

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

- 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)

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.

_SILICON_LABS_32B_SERIES_2 definition.
This PR ensures that the defines are explicit, and that #else

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.

- 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

cortexm_common: Remove read in ICSR register operations
...
All bits in the ICSR register in the cortexm system control block are
either read-only or don't have an effect when writing a zero. A
read-modify-write cycle is thus not required when writing bit flags in
the register. This commit removes the reads in the read-modify-store
patterns for this register.

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/stm32: implement reset to bootloader
...
The STM32 line of microcontrollers comes with a bootloader in the ROM.
It provides the option to flash the device firmware in DFU mode (USB)
or via UART or SPI.
To enter the bootloader we have to jump to a specific address in memory,
but before reset the CPU to make sure the system is in a known state.
This enables us to use the usb_board_reset module on all STM32 platforms.

drivers/wdt: Add feature to indicate a configurable warning period
...
This adds the feature `periph_wdt_warning_period` that indicates that a
platform WDT driver implementation supports a configurable
CONFIG_WDT_WARNING_PERIOD.

stm32/dma: add setup and prepare functions
...
This commit adds two new functions to the DMA peripheral code for the
stm32. The setup function allows for a one-time setup of peripheral
config. The prepare function does the per-transfer setup. This allows
for a single setup call during the peripheral lock step and a
per-transfer call to the prepare function.

nrf52/i2c: Use mutex and IRQ for blocking
...
This commit enhances the I2C code of the nRF52 family to block on a
mutex while the I2C transfer is busy. The mutex is unlocked in the ISR
when it is trigger by either a stop condition or an error condition.

cpu/stm32/Makefile.features: capture whole family
...
All members of the stm32f401* family (etc) don't have the HWRNG
peripheral.
Apply a broader wildcard so we don't have to touch this file when
adding new boards with slightly different MCUs.

The old limitation is not valid anymore, we can evaluate $(CPU_MODEL)
here directly.
The output of
make -C tests/periph_hwrng info-boards-supported | wc -w
remains the same.

...
`usbdev_stm32.h` will pull in `usb.h` which causes an error if
`USB_H_USER_IS_RIOT_INTERNAL` is not set.
Turns out this include is not needed, so just drop it.
