Also, add a "real world" example in AVRA tests, a blink program on
a ATtiny45. Some instructions are commented out because they aren't
implemented yet, but not many.
The output of the program has been verified against AVRA's own
output.

zasm: little drive-by optimization
...
Use IX directly for argspec rows instead of going through DE. It saves a bit
of processing. The code was this way because I initially didn't use IX at all,
so as code evolved, that DE translation stayed as an artifact.

Fix filesystem in shell emulator
...
We now treat the block device as fixed-size rather than trying to grow it in response
to kernel activity.
Previously, if you tried to create 2 files in a row, only the first 1 would actually appear,
because the device only ever got larger when a byte was written immediately past the end of
the device.
Now we just let the kernel write bytes to the disk anywhere, so new files can be created even
when the previous file is not completely full.
Also, fix buffer overrun in reading filesystem image, and use a more idiomatic fgetc loop.

By uploading a BASIC loop and then run it, we can reduce the serial

Rewrite uploadb.py in perl
...
I know, this is silly, but I'm moving tools to something a bit closer to the
system. I consider perl to be more system-like than python for a simple reason:
perl is part of the OpenBSD base system and python is not.
Also, I'm learning perl and using this as an opportunity.
