Julius Werner d8086876a7 lzma: Return correct amount of decompressed bytes
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.

Gabe Black c1a20f0cb8 LZMA: Add a version of ulzma which takes the input and output buffer sizes.
This new version is used to implement the version which doesn't take the
input and output buffer sizes.

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This was the original intention for this code, but an outdated version of the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 1ee2c6dbdf libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.
When libpayload header files are included in the payload itself, it's possible
that the payloads config settings will conflict with the ones in libpayload.
It's also possible for the libpayload config settings to conflict with the
payloads. To avoid that, the libpayload config settings have _LP_ (for
libpayload) added to them. The symbols themselves as defined in the Config.in files
are still the same, but the prefix added to them is now CONFIG_LP_ instead of just
CONFIG_.

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.

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.
