In the past, QmdlReader was written to share a trait with DiagDevice, so
it had to pretend to be reading MessagesContainers. This needlessly
complicated both its code as well as that of consumers'. Instead,
QmdlReader now returns a stream of diag Messages.
QmdlReader also automatically detects if it's reading a compressed QMDL
stream or not.
Additionally, QmdlReader no longer can be bounded by a filesize limit,
and instead relies on HDLC message framing to detect file truncation.
This works for both compressed and uncompressed QMDL files.
This reworks the QmdlWriter to output gzipped QMDL files by default,
and allows QmdlReader to operate on either compressed or uncompressed
QMDLs.
QmdlReader has been significantly rewritten to expose a single AsyncRead
interface to both compressed and uncompressed QMDL sources.
...and make a small UI change so that folks won't get concerned about parsing errors.
Right now all the "undecoded extensions" noise goes into
rayhunter-daemon.log, and users get concerned about it when browsing
that through the UI.
See https://github.com/EFForg/rayhunter/issues/334
Severity levels low, medium, high are now exposed to the UI in form of
dotted, dashed and solid lines. The line on the UI represents the
highest-so-far severity seen.
Originally this was intended to be represented by Yellow/Orange/Red, but
this would mean yet another divergence for colorblind mode. This is
colorblind-friendly by default (I think...)
As part of this, simplify EventType so that it becomes a flat "level"
enum without nested variants.
There is also a new debug endpoint that allows one to overwrite the
display level directly for testing.
