interrupts: modify handling of interrupt state

Interrupt state edge detection and wait states combined into multi

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.

correct a few goofed up opcode descriptions.

get_d5 and get_r5: remove trailing slash on last macro line

add get_vd5: get_vd5 pulls in from get_d5 plus loads from register...
removes one definate instance of a possible double load, also
potentially removes double loads during tracing.

get_d5_b3 changed to get_vd5_b3: as all instances use the value of
reg d.  get_vd5_b3 pulls in from get_vd5.  reduces one definate
instance for potential of double loads and possibly reducing
the potential during tracing.

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
load during tracing.

get_p2_k6 changed to get_vp2_k6: register load was moved into the macro
as both instances need the value loaded from the register pair.

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.

16-bits is not large enough if using RAMPZ

so a 16-bit variable is not large enough to hold it.
