Flashrom performs a self-check on every startup before it even starts to
initialize any programmer.

That way, compiler errors and code errors will be caught before they can
do any harm. This patch adds an eraseblock structure self-check. It also
modifies the self-check code to consistently run all checks even if one
check failed.

This is not just for fun. We hit a real bug on BSD with the outl macros.
The macro variable tmp collided with the tmp from outer scope.

If neither internal (old default) nor dummy (safe default) programmer
are selected, we must pick a sensible default programmer.

Since there is no reason to prefer a particular external programmer,
we abort compilation if more than one of them is selected. If only one
is selected, it is clear that the user wants that one to become the
default. This fixes single-programmer compilation.

Rule of thumb: Diagnostic programmer init messages are msg_pdbg, all
other debug stuff (except warnings, which should be pmsg_pinfo or
msg_perr) is msg_pspew.

This makes "flashrom -p dummy -V" output a whole lot more readable
(try it!). In case someone wants the full barfed output, it is
possible to specify -VV instead of -V.

The msg_* macros won't compile as is if you use more than one parameter
(i.e.

have a format string and a variable). There are two alternative styles:
GNU or C99 variadic macros. While C99 has limitations compared to the
GNU extensions, these limitations do not affect our macros, so I decided
to go with the standard way.

I adjusted whitespace a bit to have aligned values (cosmetic change).

This allows us to have one common probe_jedec function instead of half a
dozen wrappers. The trick here is to have FEATURE_ADDR_FULL==0 and thus
default to unmasked addresses. That way, we only have to annotate chips
which need small address masks.

All functions which just call probe_jedec and then map flash registers
are replaced by probe_jedec. All functions which call probe_jedec, map
flash registers and do something else can at least eliminate mapping
flash registers.
Fix logic inversion in probe_jedec to map flash registers on success
instead of on failure.
Change a few TIMING_IGNORED to TIMING_FIXME where probe_jedec is used.

Total savings: One probe function simplified, three probe functions
eliminated.

Programmer debug messages during programmer init/shutdown are useful
because they print hardware settings and desired configuration.

They help in getting a quick overview of hardware and software state on
startup and shutdown.

Programmer debug messages during flash chip access are mostly a
distraction in logs and should only be enabled if someone is having
problems which are suspected to stem from a programmer hardware or
programmer software bug. Disable those messages by default, they can be
reenabled by #define COMM_DEBUG in the affected programmer file.

An added benefit is a tremendous size reduction in verbose
probe/read/write/erase logs because only flash chip driver messages
remain. In some cases, logs will shrink from 65 MB to 10 kB or less.

The right(tm) fix would be two different debug levels (DEBUG and SPEW)
and the ability to differentiate between programmer debug messages and
flash chip debug messages. Until the design for the message printing
infrastructure is finished, this is the best stop-gap measure we can
get.

And rename them accordingly. For now, main() just calls cli_classic(),
but alternative frontends can be switched in main().
Annotate remaining help texts with CLI dependency inside flashrom.c with
a FIXME comment.

Now people can go and create different frontends and be happy. Please
note that any other frontend will have to sort of duplicate the probing
code in cli_classic.c. Refactoring that part of the code is possible,
but not easy because we still want to print instructive help messages
for users.

The patch converts jedec functions into mask-based generics which can
be used for many chip provided the only changes are the addresses are
converted from 0x5555/0x2AAA to 0x555/0x2AA or similar.

The patch mostly changes jedec.c, but a few other files are changed
because they use the jedec functions within their own functions.

The patch also adds a copyright line to flashchips.c because of my
recent work in converting AMD and Atmel chips to use struct erase_block.
