Depending on the client and use-case the current minimal timeout
value of 5 ms could be too high, lowering it to 1 ms stays within
the limit imposed by most timer drivers.
Issue #4990.
When the wait value is too small the HALT attempt turnes into
busy-polling in the VMM. To prevent that always wait a minimal
amount of time.
Issue #4990.
This patch removes the obsolete 'io_progress_elem', which was wrongly
enqueued to the 'read_ready_waiters' fifo and not dequeued at
destruction time.

Remove 'usb_hid', 'usb_net', 'usb_modem' from dde_linux port. These
versions have been updated to Linux 6.1.20 which uses the 'linux.port'
file.
issue #4958
The driver is superseded by the USB network driver (usb_net) which also
contains MBIM support for LTE modems previously provided by this
driver.
issue #4958
The drivers uses the 'virt_linux' api and the current lx_kit
implementation. It is a drop-in replacement for the Linux 4.16.3 based
version.
issue #4958
NCM tries to batch TX packets using timeouts (500us) and does not send packets
before 3 packets are in the submit queue. Timeouts take milliseconds on
dde_linux which leads to delayed ACKs and poor performance for the RX case.
Therefore, we send small packets (<100 Bytes) immediately without batching (it
might be an ACK or last packet of a larger transfer).
issue #4958
The PinePhone Modems' CDC Ethernet Interface does not respond if RX/TX queue size
is greater 12 (experimentally determined), the default would be 60, meaning 60
RX Bulk URBs are sent at once to the device.
issue #4958
A WRITE_ERR_WOULD_BLOCK may occur when large reports are written to a file
system because this fills up the submit queue of the packet-stream interface.

This commits introduces changes to test number 4, so it must keep
more than one PKG. Also, it introduces a 5th test to verify that the
<remove_all/> functionality does delete everything in the depot.
Issue genodelabs#4866
This commits introduces improvements to the test functions to avoid
code duplication, and renames these functions to reflect better what they
are used for.
Issue genodelabs#4866
The last character should only be skipped if a `\0` or `\n` is found. If
the string ends without such a character or the maximum line length is
hit, we do not skip the last character.

Dynamically loading the `compat-libc` breaks `fork(2)` on Genode.
Switch `compat-libc` to a special api package that provides a source
file for statically linking the library, analogous to the `blit`
package. This also requires a quirk in Goa but should prevent breaking
`fork()` and removes the runtime and archive dependencies for Rust
packages using `compat-libc`.

Implement FBSD_1.0 versions of libc functions ('stat', 'fstat'). The
functions are versioned with @FBSD_1.0, and therefore, will not clash
with libc during linking. However, to be called by our dynamic linker,
the library must be before libc in the NEEDED section of the binary
using it. This requires the lib to be in front of libc in the LIBS
variable. The library currently will call libc 'stat' and 'fstat' by
looking up the symbols via 'dlsym'.

Some Ubuntu installations (e.g., 20.04) create installation disks with
strange C/H/S MBR partitions like 3988/255/2. Normally, VirtualBox reads
the MBR to guess disk geometry information for the virtual BIOS.
Unfortuantely, the strange values from Ubuntu lead to a heavy
virtual-disk activity on boot. Therefore, this commit forces the use of
calculated values based on the assumption that large disks use LBA
addressing anyway.
Fixes#4978
