sim_hex: Only decrement maxlen in read_hex_string when a byte is added to the array

Without this fix, the output to the buffer would be limited to maxlen/2 bytes
instead of maxlen. It is obvious from the implementation that the latter
behavior is the expected one, so the function has been altered to reflect that.

fifo: prevent potential misuse of _get_write_size()
Commit d627c8d7a179684fed0ce0e34684fa4e2f9a8806

fifo: prevent potential misuse of _get_write_size()

Using the number obtained from _get_write_size() and writing that many
items to the fifo yields to _isempty() becoming true and not to
_isfull() becoming true.

I got caught assuming the latter.

To avoid thinking about edge cases and prevent potential misuse of
_get_write_size(), I suggest that it returns one unit less, thus, a
number between 0 and (fifo_size-1).  E.g., if there is only one place
left in the fifo, i.e., _isfull() is true, it then returns 0, preventing
us to fill that place and get into a wrap overflow situation.

(Michel: Thanks for the great architecture you laid out and the great
code.)

flash: Add support for TEMPPAGE writing.

The proper way to write to flash on the AVR is to write
to the temp page and then write that temp page to flash.
This allows cancellation with the RWWSRE bit for clearing
out the temp page without writing it to flash.

This fixed a bug where the RWWSRE bit was being set in a
command, but the flash driver was improperly writing whatever
was in r0/r1 to the first address in the page, overwriting
what was already there. In reality, the code running on the
core was trying to just flush the temp page or unlock the read
while write section.

add get_vd5_b3_mask: two instances use b3 as a mask, get_vd5_b3_mask
pulls in from get_vd5_b3.

add get vh4_k8: get_vh4_k8 pulls in from get_h4_k8, removes the extra
line to pull in from the register...  removes possible double

get_p2_k6 changed to get_vp2_k6: register load was moved into the macro

add get_io5 and get_io5_b3mask: get io5_b3 and get_io5_b3mask pulls in
from get_io5...  most instances using get_io5_b3 take bit
number and use it as a mask, get_io5_b3mask does that by default.

get_o12: rcall and rjmp both left shift the value back before using
the offset...  the macro just calls for one less bit to be
shifted...  during trace we then make the extra shift as needed.

sim_core: reworked register macros and descriptor lines

reworked register macros and instruction descriptor lines to more
 closely follow avr data sheet insruction (and avr instruction wiki)
 references. register macro usage (with few exceptions) have been worked
 throughout the core to be more uniform and consistent.  most notably d
 is used nearly uniform throught the avr instruction set references,
 prior the core intermixed the usage of the opcode registers d and r
 notation.

lpm & elpm, trace bug fixed... tracing would always show lpm Z+ regardless of
 the actual operation performed...  more importantly than that, looking
 at the instruction data sheet reference, the relevant bit is bit 1
 in the opcode...  prior op was equal to opcode & 3 similar to ld/st
 instructions...  the original lpm checked for op == 1 and the
 reworked elpm checked for op == 3.  this has been corrected for
 both opcode implimentations by setting op to opcode & 1 and just
 using op to flag for post increment.

flash: add support for RWWSRE/RWWSB bits in SPMCR

The Self Program Memory Control Register (SPMCR) has a bit for enabling
the read while write section (RWWSRE). This is also used for clearing
the temporary page buffer that is used for page writing (PGWRT). The
read while write section busy (RWWSB) allows the application developer
to know when the RWW section is accessible and when programming of it
has completed.

This commit does not wire up the behavior but just allows the flash
structure to understand that it supports a RWW section.

uart_pty: Fix the race condition

There had been a race condition in there for a rather long while,
I've finaly tracked it down to a small idiotic change of trying to
flush a buffer from the wrong thread.
Removing that flush makes it works properly as intended, without the

spi: Clear SPIF when writing to SPDR

The manual says the SPIF bit is cleared when accessing (i.e. reading _or_
writing) the SPDR register after an interrupt is raised. By clearing SPIF
on a write to SPDR, the following code starts to work:

   SPDR = 0xff; loop_until_bit_is_set (SPSR, SPIF);
   SPDR = 0x00; loop_until_bit_is_set (SPSR, SPIF);

(where the bytes are arbitrarily chosen). This didn’t work before as the
SPIF bit wasn’t cleared by the second write to SPDR, so the second loop
turned into a no-op. This caused the write timer for the first byte to be
overwritten by the write timer for the second. Consequently, the first byte
never got transmitted.
