When running sandbox with lots of console output, the vidconsole slows
things down significantly since it renders truetype fonts to the
internal framebuffer. Add a -Q/--quiet_vidconsole command-line option
that removes vidconsole from stdout and stderr, using only the serial
console.
This can provide a ~300x speedup for output-heavy operations.

Add support for running tests in parallel across multiple sandbox

test: Various improvements to unit-test infrastructure
This series adds several improvements to the unit-test infrastructure:
- Move disk images to the persistent-data directory so they don't
pollute the source tree
- Add a way to keep pytest-created artefacts for faster iteration on
C tests
- Add a helper to simplify running manual unit tests from Python
- Allow combined flags with the ut command (e.g. -Efm)
- Add a -E flag to emit machine-readable result lines
- Add a -P flag to distribute tests across parallel workers
- Add -m as an alias for -f (force manual tests)

The ut command shows test output but does not provide a machine-readable
indication of whether each individual test passed or failed. External
tools must rely on heuristics like scanning for failure patterns in the
output.
Add a -E flag that emits an explicit result line after each test:
Result: PASS: test_name: file.c
Result: FAIL: test_name: file.c
This allows tools to reliably determine per-test pass/fail status
without fragile pattern matching. The flag is optional to maintain
backward compatibility with existing scripts.

The current argument-parsing logic uses switch (str[1]) which only
processes the second character of each argument. This prevents combining
multiple single-character flags in one argument (e.g., -fm).
Refactor the code to use a for loop that iterates through all characters
in the argument. For flags that take a value (like -r and -I), use goto
to skip the rest of the argument after processing.
This allows combined flags like -fmR instead of requiring -f -m -R.

- Fix fscrypt_match_name to do actual name comparison
Filesystem operations:
- Add directory listing (opendir/readdir/closedir)
- Add file existence check (exists)
- Add file size query (size)
- Add file read support (read)
- Add UUID query (uuid)
- Add filesystem statistics (statfs)
New command:
- Add fsinfo command to display filesystem statistics
Testing:
- Add comprehensive unit tests for all operations
- Enable fsuuid command for sandbox testing

When restarting U-Boot in lab mode, ensure_spawned() sets the timeout
to TIMEOUT_MS (30 seconds) before calling _wait_for_boot_prompt(). In
lab mode, _wait_for_banner() is skipped, so TIMEOUT_PREPARE_MS is never
restored.
This causes tests that boot into Linux and then restart U-Boot (like
test_distro_script) to fail with a timeout if the board takes more than
30 seconds to reset and boot.

An attempt to add the already added LMB region using
lmb_add_region_flags() ends up in lmb_addrs_overlap() check, which
eventually leads to either returning 0 if 'flags' is LMB_NONE, or -1
otherwise. It makes it impossible for the user of this function to catch
the case when the region is already added and differentiate it from
regular errors. That in turn may lead to incorrect error handling in the
caller code, like reporting misleading errors or interrupting the normal
code path where it could be treated as the normal case. An example is
boot_fdt_reserve_region() function, which might be called twice (e.g.
during board startup in initr_lmb(), and then during 'booti' command
booting the OS), thus trying to reserve exactly the same memory regions
described in the device tree twice, which produces an error message on
second call.
Return -EEXIST error code in case when the added region exists and it's
not LMB_NONE; for LMB_NONE return 0, to conform to unit tests
(specifically test_alloc_addr() in test/lib/lmb.c) and the preferred
behavior described in commit 1d9aa4a283 ("lmb: Fix the allocation of
overlapping memory areas with !LMB_NONE"). The change of
lmb_add_region_flags() return values is described in the table below:
Return case Pre-1d9 1d9 New
-----------------------------------------------------------
Added successfully 0 0 0
Failed to add -1 -1 -1
Already added, flags == LMB_NONE 0 0 0
Already added, flags != LMB_NONE 0 -1 -EEXIST
Rework all affected functions and their documentation. Also fix the
corresponding unit test which checks reserving the same region with the
same flags to account for the changed return value.
No functional change is intended (by this patch itself).

At the moment the LMB allocator will return 'success' immediately on two
consecutive allocations if the second one is smaller and the flags match
without resizing the reserved area.
This is problematic for two reasons, first of all the new updated
allocation won't update the size and we end up holding more memory than
needed, but most importantly it breaks the EFI SCT tests since EFI
now allocates via LMB.
More specifically when EFI requests a specific address twice with the
EFI_ALLOCATE_ADDRESS flag set, the first allocation will succeed and
update the EFI memory map. Due to the LMB behavior the second allocation
will also succeed but the address ranges are already in the EFI memory
map due the first allocation. EFI will then fail to update the memory map,
returning EFI_OUT_OF_RESOURCES instead of EFI_NOT_FOUND which break EFI
conformance.
So let's remove the fast check with is problematic anyway and leave LMB
resize and calculate address properly. LMB will now
- try to resize the reservations for LMB_NONE
- return -1 if the memory is not LMB_NONE and already reserved
The LMB code needs some cleanup in that part, but since we are close to
2025.01 do the easy fix and plan to refactor it later.
Also update the dm tests with the new behavior.
