When developing software that has to be flashed to a flash chip to be
executed, it often takes a long time to read the current flash contents
(for flashrom to know what pages to erase and reprogram) each time
when writing the new image. However, when the flash was just reprogrammed,
its current state is known to be the previous image that was flashed
(assuming it was verified).
Thus, it makes sense to provide that image as a file for the flash contents
instead of wasting valuable time read the whole flash each time.

Use `enum flashrom_log_level` instead to avoid further confusion.

Update `enum flashrom_log_level` to match `enum msglevel` again.
They diverged already. Found by clang.

The buffer passed to flashrom_image_write() isn't `const`. It might be
altered for full verification (with mixed contents if a layout is being
used).

Add an option --ifd to read the ROM layout from an Intel Firmware
Descriptor (IFD). Works the same as the -l option, if given, -i
specifies the images to update.
v2: o Rebased on libflashrom, use libflashrom interface.
o Use functions from ich_descriptors.c.
v3: o Move ich_descriptors.o to LIB_OBJS, thus build it independent
of arch and programmers.
o Bail out if we aren't compiled for little endian.
o Update flashrom.8.tmpl.
v4: o Incorporated David's comments.
o Removed single-character `-d` option.
v5: Changed region names to match the output of `ifdtool --layout ...`

This adds a minimal libflashrom interface based on the draft in the
wiki. While the glue code in libflashrom.c is build on top of the
existing code instead on overhauling it, the interface in libflashrom.h
is supposed to be stable. So we can keep the interface and adapt
internals later if favoured, without breaking clients.
A new make target, libinstall, is also added. It installs libflashrom.a
and libflashrom.h in lib/ and include/ dirs respectively.
Hooking this into the build would break linking of the CLI and is post-
poned until that got fixed.
v2: Rebase and fixes by Anton Kochkov.
v3: o fl_image_*() rewritten with layout support (touch only included regions).
o Moved read/erase/write/verify operations to flashrom.c.
o Added layout pointer and flags to the flash context.
v4: Removed libflashrom.o from LIB_OBJS until CLI is adapted.
v5: o Incorporated David's comments.
o Added `fl_flashprog_t` as dummy parameter to hide the fact that
we have global state all around, and for future-proofness ofc.
v6: o Change namespace prefix to flashrom_.
o Remove typedefs.
