When typedef is used with structs, enums, and to create new typenames,
readability suffers. As such, restrict use of typedefs only to
creating new data types.
The 80 character limit is intentionally ignored in this patch in order

Add XDR functions and use them to convert the ELF headers
to native headers, using the Elf64 structs to ensure we accomodate
all word sizes. Also, use these XDR functions for output.
This may seem overly complex but it turned out to be much the easiest
way to do this. Note that the basic elf parsing function
in cbfs-mkstage.c now works over all ELF files, for all architectures,
endian, and word size combinations. At the same time, the basic elf
parsing in cbfs-mkstage.c is a loop that has no architecture-specific
conditionals.
Add -g to the LDFLAGS while we're here. It's on the CFLAGS so there is
no harm done.
This code has been tested on all chromebooks that use coreboot to date.
I added most of the extra checks from ChromeOS and they triggered a
lot of warnings, hence the other changes. I had to take -Wshadow back
out due to the many errors it triggers in LZMA.

After removing a file sandwiched between two other files, that file
could no longer be re-added at the same location. cbfstool tried to
add the file, and a new "empty" entry, which, together, would no
longer fit, so it continued checking for the next available space.
Change the behavior to add the file if there is enough space for the
file alone, then only add the "empty" entry if there is enough space
for it.

During the update_fit step, 'file_length' is used to determine how many
bytes are left in the CBFS file. It was decremented in a loop from an
array 'mcus[num_mcus].size', but 'num_mcus' was incremented right before.
Since 'mcus' is memset(0) externally, 'file_length' was never decremented.
The loop exited when it reached a dummy terminator, usually 48 bytes of 0
which are internationally added to microcode blobs in coreboot. However,
if that terminator is removed, the loop doesn't stop and continues until
it segfaults.

Current cbfstool implementation is relying on global variables to pass processed
data, and the calculation of address is based on x86 architecture (ex, always
assuming 0x0000 as invalid address), not easy to be used on platforms without
top-aligned memory mapping. This CL is a first step to start a new cbfstool
without global variables, and to prevent assuming memory layout in x86 mode.
The first published APIs are for reading and writing existing CBFS ROM image
files (and to find file entries in a ROM file).
Read cbfs_image.h for detail usage of each API function.

Many functions in cbfstool need to deal with a memory buffer - both location and
size. Right now it's made by different ways: for ROM image using global variable
(romsize, master_header); and in cbfs-* using return value for size and char**
to return memory location.
This may cause bugs like assuming incorrect return types, ex:
uint32_t file_size = parse(); // which returns "-1" on error
if (file_size <= 0) { ...
And the parse error will never be caught.
We can simplify this by introducing a buffer API, to change
unsigned int do_something(char *input, size_t len, char **output, ...)
into
int do_something(struct buffer *input, struct buffer *output, ...)
The buffer API will be used by further commits.

The 'host_bigendian' variable (and functions relying on it like ntohl/htonl)
requires host detection by calling static which_endian() first -- which may be
easily forgotten by developers. It's now a public function in common.c and
doesn't need initialization anymore.

The ELF parsing and payload building in add-flat-binary command should be
isolated just like mkpayload and mkstage.
Since the add-flat-binary command creates a payload in the end , move payload
processing to cbfs-mkpayload.c.
To test:
cbfstool coreboot.rom add-flat-binary -f u-boot.bin -n fallback/payload \
-l 0x100000 -e 0x100020
To verify, get output from "cbfstool coreboot.rom print -v":

Add -v (verbose) to every command, and allow printing debug messages.
Revise logging and debugging functions (fprintf(stderr,...), dprintf...)
and verbose message printing with following macros:
ERROR(xxx): E: xxx
WARN(xxx) W: xxx
LOG(xxx) xxx
INFO(...) INFO: xxx (only when runs with -v )
DEBUG(...) DEBUG: xxx (only when runs with more than one -v)
Example:
cbfstool coreboot.rom print -v
cbfstool coreboot.rom add -f file -n file -t raw -v -v
Normal output (especially for parsing) should use printf, not any of these
macros (see usage() and cbfs_locate(), cbfs_print_directory() for example).

Currently "cbfstool locate" outputs a hex number without "0x" prefix.
This makes extra step (prefix 0x, and then generate another temp file) in build
process, and may be a problem when we want to allow changing its output format
(ex, using decimal). Adding the "0x" in cbfstool itself should be better.

cbfstool.c uses lots of global variables for command line options and all named
as "rom*". This may be confusing when other global variables also start with
rom, ex: int size = rom_size + romsize;
(rom_size is from command line and romsize is the size of last loaded ROM image).
If we pack all rom_* into a struct it may be more clear, ex:
do_something(param.cbfs_name, param.size, &romsize);
