Switches all of the previous `state->verbose`-gated `eprintln!` calls to
use macros from the `log` crate, trying to map them onto the previous
verbosity levels, more or less following this mapping:
0. off
1. error/info/warn (depending on context)
2. trace
This additionally includes a bunch of logic/branch reformatting (and
occasional missed constants), since getting rid of all the gating on
verbose provided ample opportunities to clean up the code. Hopefully I
didn't break too much in the process!
This commit gets the Rust code to compile! 🎉
Additionally, it fixes all of the commented out code that was failing
translation from C due to the use of unions, namely around the APDU
messages.
It does a fair amount of reformatting around branches, with the net
result hopefully being something actually a bit closer to the C code,
and a straightforward list of `if` statements.
It also removes all of the remaining externs that aren't supposed to be
externs, replacing them with a more straightforward usage of the module
system.
Finally it fixes all errors and warnings (relating to e.g. usage of
uninitialized memory), in addition to most clippy lints! (some have
been explicitly disabled)
All that said, it still doesn't do anything: it needs to be wired up to
a PCSC library first before that will be possible. But hey, it compiles!
