libflashprog: Start a new API for chip enumeration

For now, allow to query all chips, their vendor, name and size.

There's a tricky optimization coming up: We don't want to allocate
additional memory when enumerating the chip database. But, we also
want to use the same API interface to access information about de-
tected chips, which requires dynamic memory.  So we have to handle
these distinct cases explicitly.  Where `struct flashprog_chips *`
is used, we set it to the special value `FLASHCHIPS_DB`  to denote
the flash database. For `struct flashprog_chip *` pointers, we add
chip_from_db(), which tells us whether the given pointer is within
the database range.
