Improve error checking in file write, chip read and chip verify.
Refactor the read routines a bit to split reading from file writing.

This is a 1 MB SPI chip that seems to be straightforwardly related
to the AMIC A25L40PU, which has half the capacity but is otherwise
identical.

Datasheet is at http://www.amictechnology.com/pdf/A25L80P.pdf



flashrom -VE, -Vr, and -Vw has been tested using the AMD SB7x0
interface. Everything works fine... at least, I used it to upgrade my
BIOS and I've been able to reboot.

SPI chips never should use read_memmapped. The SPI master code might
decide that read_memmapped is fine for this chip, though, in a lower
layer.

This led to wildly differing syntax for programmer parameters, and
it also voids pretty much every assumption you could make about
programmer_param. The latter is a problem for libflashrom.

Use extract_param everywhere, clean up related code and make it more
foolproof. Add two instances of exit(1) where we have no option to
return an error. Remove six instances of exit(1) where returning an
error was possible.

WARNING: This changes programmer parameter syntax for a few programmers!

If a programmer has untested or non-working write/erase code, but
probing/reading works, it makes sense to protect the user against
write/erase accidents. This feature will be used by the Nvidia MCP SPI
code, and it also might make sense for the gfxnvidia driver which has
non-working write/erase.

Constify variables where possible.
Initialize programmer-related variables explicitly in programmer_init to
allow running programmer_init from a clean state after
programmer_shutdown.
Prohibit registering programmer shutdown functions before init or after
shutdown.
Kill some dead code.
Rename global variables with namespace-polluting names.
Use a previously unused locking helper function in sst49lfxxxc.c.

This is needed for libflashrom.

Effects on the binary size of flashrom are minimal (300 bytes
shrinkage), but the data section shrinks by 4384 bytes, and that's a
good thing if flashrom is operating in constrained envionments.
