The LZMA functions are supposed to return the decompressed size, but
what they actually return is just an unaltered field from the LZMA
header that is *supposed* to contain the decompressed size. Apparently
some encoders just overshoot that for no good reason. This patch changes
the code such that the actual amount of decompressed bytes is returned.
BRANCH=smaug
BUG=None
TEST=Printed output bytes when decompressing kernels with LZMA in
depthcharge, noted that amounts now make sense.

This new version is used to implement the version which doesn't take the
input and output buffer sizes.

(cherry picked from commit 465d167ad2f6a67d0b2c91fb6c68c8f9a09dd395)
libpayload: Make lzma truncation non-fatal.
If the size the lzma header claims it needs is bigger than the space we have,
print a message and continue rather than erroring out. Apparently the encoder
is lazy sometimes and just puts a large value there regardless of what the
actual size is.
This was the original intention for this code, but an outdated version of the
patch ended up being submitted.

Use memcpy to access a uint32_t that's inherently unaligned due to the layout
of the LZMA header format.
Built and booted on Daisy and saw a data abort go away. Built and booted
into developer mode on Link and verified that bitmaps were
decompressed/displayed correctly.

Add cbfs core from coreboot into libpayload, and to support lzma decode,
add coreboot's lzma code, too. Carl-Daniel agreed to relicense the
lzmadecode wrapper as BSD-l, solving licensing problems.
