Add SPI flash emulation capability to the dummy programmer

You have to choose between
- no emulation
- ST M25P10.RES SPI flash chip (RES, page write)
- SST SST25VF040.REMS SPI flash chip (REMS, byte write)
- SST SST25VF032B SPI flash chip (RDID, AAI write)
Example usage: flashrom -p dummy:emulate=SST25VF032B

Flash image persistence is available as well.
Example usage: flashrom -p dummy:image=dummy_simulator.rom

Allow setting the max chunksize for page write with the dummy
programmer.
Example usage: flashrom -p dummy:spi_write_256_chunksize=5

Flash emulation is compiled in by default. 

This code helped me find and fix various bugs in the SPI write code
as well as in the testsuite.

Corresponding to flashrom svn r1220.
