[flashrom] Flashrom.c code analysis: cli, programmer, flasher code

[Sean Nelson]

This patch breaks out the cli, programmer, and flasher code into 
separate files. The only file that will not cleanly compile is cli.c, 
which is looking for the table defined in programmer.c. Files were 
compiled with "gcc -c -o %.o %.c" in this test. I don't expect this 
patch to be committed so no sign-off. Note, the breakdown is what I 
assume to be the cli, programmer related code, and flash routines like 
read, erase, probe, verify, and etc. I didn't {re,}write any functions.
