Flashmap, or simply fmap, is a binary data format for describing
region offsets, sizes, and certain attributes and is widely used by
coreboot. This patch adds support for the fmap data format version 1.1
and adds --fmap and --fmap-file arguments.
Using --fmap will make flashrom to search the ROM content for fmap
data. Using --fmap-file will make flashrom search a supplied file
for fmap data.
An example of how to update the COREBOOT region of a ROM:
flashrom -p programmer --fmap -w coreboot.rom -i COREBOOT
flashrom -p programmer --fmap-file coreboot.rom -w coreboot.rom -i COREBOOT
The fmap functions are mostly copied from cbfstool.
Currently it is made mutually exclusive with other layout options until
we are more clever about this input.

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.

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.
