Sol Boucher 0e53931fee cbfstool: Clean up in preparation for adding new files
This enables more warnings on the cbfstool codebase and fixes the
issues that surface as a result. A memory leak that used to occur
when compressing files with lzma is also found and fixed.
Finally, there are several fixes for the Makefile:
 - Its autodependencies used to be broken because the target for
   the .dependencies file was misnamed; this meant that Make
   didn't know how to rebuild the file, and so would silently
   skip the step of updating it before including it.
 - The ability to build to a custom output directory by defining
   the obj variable had bitrotted.
 - The default value of the obj variable was causing implicit
   rules not to apply when specifying a file as a target without
   providing a custom value for obj.
 - Add a distclean target for removing the .dependencies file.

BUG=chromium:461875
TEST=Build an image with cbfstool both before and after.
BRANCH=None

Stefan Reinauer 2dd161f556 cbfstool: Clean up code
cbfstool has diverged between coreboot upstream and the chromium tree.
Bring in some of the chromium changes, in particular the useful remainders
of cbf37fe (https://chromium-review.googlesource.com/176710)

- fix coding style
- mark unused variables explicitly unused
- remove some dead code

Gabe Black dbd006b082 cbfstool: Propogate compression errors back to the caller.
When compression fails for whatever reason, the caller should know about it
rather than blindly assuming it worked correctly. That can prevent half
compressed data from ending up in the image.

This is currently happening for a segment of depthcharge which is triggering
a failure in LZMA. The size of the "compressed" data is never set and is
recorded as zero, and that segment effectively isn't loaded during boot.

These options seem to control the behavior of the encoder/decoder,
with comments citing a trade-off between memory usage and performance.
I removed these in a separate patch to make reverting in the future
easier, if we find these options are useful.

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
to make reviewing easier.

            cbfstool: Replace C++ code with C code

            Reviewed-on: http://review.coreboot.org/3010

In the progress of doing so, the stream position for the
input stream and output stream was not reset properly. This
would cause LZMA producing corrupt data when running the
compression function multiple times.

* unlink targets before rename on win32
* implement (crude) mkstemp for win32
* avoid open/read/close, use fopen/fread/fclose instead
* don't free certain data structures in romcc on win32 to
  avoid crashes (likely use-after-free())
* handle "\CRLF" and win32 style absolute paths (X:/ or X:\)

Patrick Georgi b7b56dd8fb New cbfstool. Works without mmap or fork/exec and
supports fixed location files. Some parts are salvaged
from the pre-commit version (esp. stage and payload creation),
others are completely rewritten (eg. the main loop that handles
file addition)

Also adapt newconfig (we don't need cbfs/tools anymore) and fix
some minor issues in the cbfstool-README.
