libflashrom: Return progress state to the library user
Projects using libflashrom like fwupd expect the user to wait for the
operation to complete. To avoid the user thinking the process has
"hung" or "got stuck" report back the progress complete of the erase,
write and read operations.
Add a new --progress flag to the CLI to report progress of operations.
Include a test for the dummy spi25 device.
Tested: ./test_build.sh; ./flashrom -p lspcon_i2c_spi:bus=7 -r /dev/null --progress
flashrom-stable:
* Closer to original libflashrom API.
* Split update_progress() into progress_start/_set/_add/_finish:
Simplifies progress calls scattered through the code base. We let
the core code in `flashprog.c` handle the total progress. Only API
is flashprog_progress_add(). Erase progress is completely handled
in `flashprog.c`. Fine grained read/write progress can be reported
at the chip/programmer level.
* Add calls to all chip read/write paths and opaque programmers
except for read_memmapped() (which is handled in follow ups).
* At least one wrinkle left: Erasing unaligned regions will slightly
overshoot total progress.
