sdcard_spi: Fix some abbreviations and names to match the spec.
The official abbreviation for CMD24 in the spec is "WRITE_BLOCK", as
opposed to "WRITE_MULTIPLE_BLOCK" for CMD25 (chapter 4.7.4,
"Detailed Command Description", table 4-24).
The byte preceeding e.g. the CMD24 block data is called "Start Block" token
(chapter 7.3.3.2, "Start Block Tokens and Stop Tran Token"). We don't
include the "token" itself for consistency, since the decoder doesn't do
that for any other tokens either.

sdcard_spi: touch up CMD24 handling
Address some nits in the SDCard (SPI mode) protocol decoder. Rename
identifiers to eliminate comments. Determine the default block size at
the start of the write command instead of the iteration over payload
data bytes. Remove a print() statement which would break regression
tests. Allow re-use of the data handler for other commands, too. Use
lower case hex digits for consistency across the source file, and
slightly unobfuscate a bit pattern check while we are here. Improve
robustness of response handlers and how internal state gets advanced.
Replace constant lookups by direct method calls.

sdcard_spi: add support for CMD24 including payload data
The previous implementation advanced from the start of CMD24 to IDLE.
This commit introduces support for the data phase and data response of
CMD24. Which results in improved usability of the decoder output, and
reduced probability of false positives (don't detect "commands" in the
payload data).
This commit addresses the missing CMD24 handling part of bug #1365.

uart: remove obsolete TODO (Python annotation for frame errors)
The "Frame error?" TODO comment on Python annotations has become
obsolete. Individual bit errors within the frame immediately get
communicated as they are detected (START, parity, STOP). The overall
frame's validity has become available with the FRAME annotation.
Internally keep track of the UART frame's validity. Emit a FRAME Python
annotation for aborted as well as for completed frames. This obsoletes a
TODO comment in the STOP bit code path.
This annotation also spans the complete frame's length, including start
and parity and stop bits, which the DATA annotation doesn't cover.
Stacked decoders can individually decide whether to strictly reference
the mere data bits section or the complete UART frame which happened to
communicate the data value.

decoder: consider reset() a mandatory decoder method
In theory support for PD reset is optional, applications are not
required to make use of it. But it's essential to receive correct
decoding results when used with the popular Pulseview mainline
application.
So let's consider the absence of the reset() method fatal. All mainline
decoders have it. Out-of-tree decoders are easy to adjust, and very
probably should support reset() as well. Thus this change is considered
beneficial, and not harmful.

uart: add support for break condition detection
There are the "traffic inspecting" wait() conditions, which check an
edge to find the start of START, then wait for sample points to grab the
bit values. Bit times are sampled in their respective center, potential
glitches around sample points get ignored.
Add another independent set of wait() conditions which check _all_ edges
regardless of any data communication. This results in the most reliable
and maintainable detection of break conditions, regardless of how they
align to data frames. Break is defined as a period of low input signal
which spans at least one frame's length. Run the edge inspection after
data inspection, which results in the most appropriate annotation output
like leading data bits (of incomplete frames), frame errors (violated
STOP bit expectations), then break conditions. This approach is most
robust in the presence of incomplete input streams.
