We've had a second version of ulzma() that would check the input and
output buffer sizes in libpayload for a while now. Since it's generally
never a bad idea to double-check for overruns, let's port it to coreboot
and use it where applicable. (This requires a small fix in the four byte
at a time read optimization we only have in coreboot, since it made the
stream counter hit the end a little earlier than the algorithm liked and
could trigger an assertion.)

This makes lzmadecode 64-bit clean (I hope).
It also cleans up a few other nits.

Flash prefers 32-bit sequential access. On some platforms ROM is
not cached due to i.a. MTRR shortage. Moreover ROM caching is not
currently enabled by default. With this patch payload decompression
is sped up by theoretical factor of 4.
Test on X201, with caching disabled:
Before:
90:load payload 4,470,841 (24,505)
99:selfboot jump 6,073,812 (1,602,971)
After:
90:load payload 4,530,979 (17,728)
99:selfboot jump 5,103,408 (572,429)

while others dislike them being extra commits, let's clean them up once and
for all for the existing code. If it's ugly, let it only be ugly once :-)
