51f51c18af block/request_stream: rename wakeup_client
This patch renames 'wakeup_client' to 'wakeup_client_if_needed' to
clarify that the method triggers signals only when needed, not on every
call.

The name 'wakeup_client' is prone to misguide users to call the function
conditionally as an optimization, thereby complicating the code, but to
no effect.

bbe3ee8dc5 block_session: server-defined payload alignment
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.

First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.

Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.

The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.

At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).

2208220c12 block session: remove Block::Session::Operations
This patch modernizes the 'Block::Session::info' interface. Instead of
using out parameters, the 'init' RPC function returns a compound 'Info'
object now. The rather complicated 'Operations' struct is replaced by
a 'writeable' attribute in the 'Info' object.

a147bdf406 hw: silent warning about unknown signal context
Triggering of an invalidated signal seems to be no real exception,
but something that occurs regularily. Therefore, the kernel warning
is of no use to developers anymore.

0ca199f89a hw: replace lock-safe log variants in kernel
As far as possible remove usage of warning/error/log in the kernel,
otherwise the kernel context might try to take a lock hold by a core
thread, which results in a syscall to block.

9e238d624e extract: discharge dependency from timer session
This patch removes the reliance of the extract tool from the libc's
behavior regarding the access of time and timing.

The extract tool is not expected to need time. However, unfortunately,
libarchive calls the 'time' function unconditionally. By adding a
dummy for 'time', we avoid bothering the libc, which would otherwise
need to obtain a time source.

6d11591d83 test-spark: rename number_of_bits -> object_size
In the original version, I used 'number_of_bits' because Ada's 'Size
returns the size in bits, not bytes. But the values (for objects) are
always a multiple of 8. On the C++ side, performing size checks at the
granularity of bits is just awkward. The term 'object size' is more
natural.

The 'aes_cbc_4k' library is simple wrapper around libsparkcrypto to
serve as a backend for storage encryption. It operates on data chunks of
4 KiB and uses AES-CBC while incorporating the block number and the
private key as salt values.

a635873568 VFS: Replace global response handlers with local handlers
Replace the I/O response handler that is passed to the VFS at
construction with an object that is dynamically attached to handles.
This object shall also accept read-ready notifications, and plugins are
encouraged to keep handles awaiting ready-ready notifications separate
from handles that await I/O progress.

Replace the use of handle lists in plugins with handle queues, this
makes the code easier to understand and the ordering of notifications to
the application more explicit.

These changes replace the use of the Post_signal_hook from all VFS
plugins, applications must assume that read-ready and I/O notifications
occur during I/O signal dispatch and use an Io_progress_handler at its
entrypoints to defer response until after signal dispatching.

aeb7e7cd7c sculpt manager: prevent double destruction
The '_currently_constructed' pointer caches the information about which
'Launched_child' is currently configured in the menu. When discarding
the runtime (e.g., when un-using a file system) at this point, this
cached pointer was not invalidated while all 'Launched_child' objects
would be freed (including the currently constructed one). On the next
attempt to construct a new child, the sculpt manager attempted to
destruct the 'Launched_child' referred by the (now outdated)
'_currently_constructed' again.
