aa8df95f7d Add "avr/" includes folder 
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.

e691dab070 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.

1b8b113536 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.

4f7a05e3b7 core: remove cpHLDE 
It wasn't used much, so I replaced its use in the kernel with direct code
and moved the routine in apps/ed, the only other place where it was used.

c002c69208 Include tools/tests/shell/test.cfs in repo 
The order in which cfspack includes its file depend on the platform. To have
tests that reliably pass, test.cfs has to be committed in.

7907687abf tools/uploadb: make it much much faster 
By uploading a BASIC loop and then run it, we can reduce the serial
communication to pure content which greatly reduces the overhead and make
the process much much faster.

8ff4b18c51 tools: add memdumpb 
In C this time. Python/Perl code is barely terser than C for these little
tools. Why bother with interpreted?

b56d6ca1c7 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.

66dacd1816 tools/emul: add "Min SP" debug value 
This gives the maximum size of the stack at any given moment during the
execution of the program. It's useful to figure out if the stack gets
dangerously close to the heap.
