(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This was the original intention for this code, but an outdated version of the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.

Gabe Black 00e5da6f25 libpayload: Don't do unaligned accesses during LZMA decompression
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.

Patrick Georgi 6de1ee4a30 libpayload: Add liblzma, libcbfs
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.
