Newer picolibc versions require some additional symbols defined in the
linker script to correctly manage alignment constraints on thread
local storage.

19242: usbus/msc: add initial Mass Storage Class support r=benpicco a=dylad
### Contribution description
This PR adds the initial support for Mass Storage Class in USBUS. This PR relies on the RIOT MTD implementation to implement the Mass Storage Class support. With the provided test application, a MTD device will be accessible as a normal storage device on your host computer.
Read and Write operations are allowed.
Multiple LUNs are supported so several MTD devices can be exported through USB.
The MSC relies on SCSI protocol to operate.
Currently there are some limitations:
Supported host : Linux & Windows (macOS is untested)
MSC cannot be used if MTD page size > 4096
MTD device must have at least 512 bytes of memory to be exported.
Please be aware that performance are not so great.
### Testing procedure
Flash `tests/usbus_msc` application on a board with at least one MTD device.
Once the shell has started, prepare one or several MTD devices to be exported using `add_lun` command.
Once ready, start the USB connection with `usb_attach`
All MTD exported should appear as` /dev/sdX` on Linux.

19331: pkg/tinydtls: Adjust defaults r=miri64 a=chrysn
### Contribution description
This adjusts two defaults in tinydtls:
* Default verbosity is set to warning. At the info level, this module produces way more output (several lines per new connection, and even per message) than is common in RIOT.
* If gcoap is used, the buffer size is adjusted to the gcoap buffer size plus overhead. Otherwise, CoAP-over-DTLS works fine until one happens to request larger resources.
### Testing procedure
* Run examples/gcoap_dtls
* Send a CoAP request from outside, eg. with `aiocoap-client 'coaps://[fe80::3c63:beff:fe85:ca96%tapbr0]/.well-known/core' --credentials testserver.json` (where testserver.json is `{"coaps://[fe80::3c63:beff:fe85:ca96%tapbr0]/*": {"dtls": {"psk": {"ascii": "secretPSK"}, "client-identity": {"ascii": "Client_identity"}}}}`).
Before, there are messages shown for every request; now there are none.
Modify `examples/gcoap/server.c` as follows:
```patch
diff --git a/examples/gcoap/server.c b/examples/gcoap/server.c
index bf2315cd01..28e1faac27 100644
--- a/examples/gcoap/server.c
+++ b/examples/gcoap/server.c
`@@` -68,7 +68,7 `@@` static const coap_resource_t _resources[] = {
};
static const char *_link_params[] = {
- ";ct=0;rt=\"count\";obs",
+ ";ct=0;rt=\"count\";obs;looooooooooooooooooooooong-attribute=\"loooooooooooooooooooooooooooooong\"",
NULL
};
```
The request passes; without this patch, it is stuck in retransmissions until "Network error: Retransmissions exceeded".
### Issues/PRs references
This contributes to making #19289 usable with a minimum level of security. (That module fills up the gcoap buffer to the brim). While the module handles the verbosity as well as it can (occasionally admitting that it lost bytes of output), the previous verbosity produces an infinite stream of stdout data. (But the default should be quiet immaterial of that particular PR).

19330: native/stdio: Explicitly provide getchar r=chrysn a=chrysn
### Contribution description
This ensures that even when libc does not implement getchar through getc, any custom stdio is still in the loop when getchar is used.
Frankly, I don't know when this broke -- I'm pretty sure custom stdio worked just a few days ago -- but either way, without this patch RIOT on native currently bypasses a configured stdio for me.
### Testing procedure
* `make -C examples/saul all debug`
* `break stdio_read`
* `run`
Without this patch, observe how the shell runs w/o ever breaking. After, lots of breakpoint hits.
This is the way it behaves for me (Debian sid, libc6:i386 2.36-8). If it works for you before this patch, we might start bisecting the differences between the systems, but we may also accept that libcs may imlpement getchar in different ways, and not all of them pass by the getc which we're patching.
### Issues/PRs references
This is needed for testing #19289.
The implementation stems from the `fgetc(3)` man page, which states that "getchar() is equivalent to getc(stdin)".
