Update the list of target triples to match
`makefiles/arch/riscv.inc.mk`. This fixes compilation with toolchains
other than the obsolete toolchain that uses the incorrect
`riscv-none-embed` triple.
19030: tests/periph_timer_short_relative_set: improve test r=benpicco a=maribu
### Contribution description
Reduce the number lines to output by only testing for intervals 0..15 to speed up the test.
In addition, run each test case 128 repetitions (it is still faster than before) to give some confidence the short relative set actually succeeded.
### Testing procedure
The test application should consistently fail or succeed, rather than occasionally passing.
### Issues/PRs references

19085: makefiles/tests/tests.inc.mk: fix test/available target r=benpicco a=maribu
### Contribution description
`dist/tools/compile_and_test_for_board/compile_and_test_for_board.py` relies on `make test/available` to check if a test if available. However, this so far did not take `TEST_ON_CI_BLACKLIST` and `TEST_ON_CI_WHITELIST` into account, resulting in tests being executed for boards which they are not available. This should fix the issue.
### Testing procedure
#### Expected to fail
```
$ make BOARD=nrf52840dk -C tests/gcoap_fileserver test/available
$ make BOARD=microbit -C tests/log_color test/available
```
(On `master`, they succeed, but fail in this PR.)
#### Expected to succeed
```
$ make BOARD=native -C tests/gcoap_fileserver test/available
$ make BOARD=nrf52840dk -C tests/pkg_edhoc_c test/available
$ make BOARD=nrf52840dk -C tests/log_color test/available
```
(Succeed in both `master` and this PR.)

19074: cpu/esp8266: build the SDK bootloader from source r=benpicco a=gschorcht
### Contribution description
This PR is a takeover of PR #17043, which is rebased to the current master and includes some corrections that became necessary after rebasing.
**Copied from description of PR #17043:**
We had four versions of pre-built bootloaders for the esp8266 with different settings of logging and color logging. These bootloaders were manually built from the SDK and shipped with RIOT-OS source code. However there are more settings that affect the bootloader build that are relevant to the app or final board that uses this bootloader. In particular, flash size and flash speed is important for the bootloader to be able to load an app from a large partition table at the fastest speed supported by the board layout and flash chip.
Another example is the UART baudrate of the logging output from the bootloader. The boot ROM will normally start at a baud rate of 74880 (depending on the crystal installed), so it might make sense to keep the UART output at the same speed so we can debug boot modes and bootloader with the same terminal.
This patch builds the `bootloader.bin` file from the ESP8266 SDK source code. The code is built as a module (`esp8266_bootloader`) which at the moment doesn't generate any object code for the application and only produces a `bootloader.bin` file set to the `BOOTLOADER_BIN` make variable for the `esptool.inc.mk` to flash.
The code needs to be compiled and linked with custom rules defined in the module's Makefile since the `bootloader.bin` is its own separate application.
The `BOOTLOADER_BIN` variable is changed from a path relative to the `$(RIOTCPU)/$(CPU)/bin/` directory to be full path. This makes it easier for applications or board to provide their own bootloader binary if needed.
As a result of building the bootloader from source we fixed the issue of having a large partition table.
### Testing procedure
Use following command to flash the application with STDIO UART baudrate of 115200 baud.
```
BAUD=74880 USEMODULE=esp_log_startup make -C tests/shell BOARD=esp8266-esp-12x flash
```
Connect with a terminal programm of your choice (unfortunatly `picocom` and `socat` don't support a baudrate close to 74880), for example:
```
python -m serial.tools.miniterm /dev/ttyUSB0 74880
```
On reset, the `esp8266-esp-12x` node shows the ROM bootloader log output
```

as well as the second-stage bootloader built by this PR (`ESP-IDF v3.1-51-g913a06a9ac3`) at 74880 baudrate.
```
I (42) boot: ESP-IDF v3.1-51-g913a06a9ac3 2nd stage bootloader
I (42) boot: compile time 11:25:03
I (42) boot: SPI Speed : 26.7MHz
...
I (151) boot: Loaded app from partition at offset 0x10000
```
The application output is seen as garbage since the `esp8266-esp-12x` uses 115200 as baurate by default.
To see all output at a baudrate of 74880 baud, you can use the following command:
```
CFLAGS='-DSTDIO_UART_BAUDRATE=74880' BAUD=74880 USEMODULE=esp_log_startup make -C tests/shell BOARD=esp8266-esp-12x flash
```
If the application is built without options, the ROOM bootloader output will be 74880 baud and the second stage bootloader and application output will be 115200 baud.

Instead of using a fixed position of the image file in the flash, the variable `FLASHFILE_POS` is used which allows to override the default position of the image in the flash at 0x10000.

Allow overriding the shell command used to auto-detect the TTY of a
board with `MOST_RECENT_PORT=1` via the `TTY_SELECT_CMD` variable.
The use case is to also detect Arduino Mega 2560 clones with cheap
USB UART bridges (for which the filter command may yield false
positives) while preferring genuine Arduino Mega 2560 boards (if
found) over the clones (as the filter for genuine boards does not yield
false positives).
Boards that are shipped with a DFU bootloader define the `dfu-util` configuration in their `Makefile.include`. However, when `riotboot_dfu` is used as the DFU bootloader, the board's `dfu-util` configuration must be overridden by the configuration as required by `riotboot_dfu` to use it to flash applications. Therefore, all `dfu-util` configurations are defined as overridable in the board's `Makefile.include` and the configuration as required by `riotboot_dfu` is included before the board's `Makefile.include`.
When trying to compile `examples/hello-world` on my 465 MHz Mendocino
I got
/home/benpicco/dev/RIOT/makefiles/toolchain/gnu.inc.mk:29: extraneous text after 'ifneq' directive
Turns out the version of `make` on Archlinux32 is newer than that in
Ubuntu 22.04, which somehow ignored the extra parenthesis.
Turns out this (t)rusty old machine is still good for writing patches :D
Hooking into the existing wrappers for `malloc()`, `calloc()`,
`realloc()`, and `free()`, the new (pseudo) module `malloc_tracing`
prints out the calls to the given functions, the program counter of
the caller, as well as the return result.
The intent is to aid debugging double-frees, invalid frees, or memory
leaks.
Modern binutils complain about segments with RWX permissions. While
this is indeed a bad habit, RIOT ignores segments permissions anyway.
(We do have a `mpu_noexec_ram` module to disable execution of all of
RAM, which would do so regardless of the segment permission.) So for
now, we can safely just disable the warning.
This fixes:
/usr/lib/gcc/arm-none-eabi/12.2.0/../../../../arm-none-eabi/bin/ld: warning: /home/maribu/Repos/software/RIOT/examples/default/bin/nucleo-f767zi/default.elf has a LOAD segment with RWX permissions
collect2: error: ld returned 1 exit status
The test for the requirement of disabling wchar_t size warnings assumed
that $(CC) is used for linking, instead of $(LINK). With GCC $(LINK)
and $(CC) happen to be (in most cases) identical, but with LLVM they
are not. This results in issues with compiling with LLVM.
GCC on some platforms does need an executable stack to generate
trampoline code, but use of nested functions is not allowed in
RIOT's code base anyway.
This allows including C headers from C++. It sadly reduced the
diagnostics on C++ code as well, were there warning may make sense as
unintended side effect. We may be able to drop that later on, when more
C APIs are properly wrapped in native C++ APIs, so that C headers do no
longer need to be compatible with C++ compilers.
In an ideal world everyone would just install `gdb-multiarch` and be
happy. However, some MCUs need magic GDB versions sprinkled with
unicorn-stardust-Espressif-patches...
Since there is little reason to have `$(target)-gdb` installed in
addition to `gdb-multiarch` if `gdb-multiarch` would work fine, let's
assume the user wants to use `$(target)-gdb` when present over
`gdb-multiarch`.

Add USE_MODULE += "stdio_uart_onlcr" to enable it.
This is named after the "onlcr" stty flag, which does the same thing.
