Commit 4d3b8a0d fixed a problem with lzma decompress where it would
run out of bytes to decompress. The algorithm needs to know how many
uncompressed bytes it is expected to produce.
However, the fix introduced a potential buffer overrun, and causes
the compression test to fail (test_compression command in sandbox).
The correct fix seems to be to use the minimum of the expected number
of uncompressed bytes and the amount of output space available. That
way things work normally when there is enough space, and return an
error (without overrunning available space) when there is not.

It seems the code tries to trick the compiler the argument
is actually used. However compilers became too smart to
fool them so easily an now warn. Gcc and clang don't seem
to emit a warning when the argument is unused. If so it
should be decorated with unused / (void).

Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

Variable uncompressedSize references the space available, while outSizeFull is
the actual expected uncompressed size. Using the wrong value causes LzmaDecode
to return SZ_ERROR_INPUT_EOF. Problem was introduced in commit afca294. While
at it add additional debug message.

The output buffer size must be correctly passed to the lzma decoder or
there is a risk of overflowing memory during decompression. Switching
to the LZMA_FINISH_END mode means nothing is left in an unknown state
once the buffer becomes full.

Updated code taken from latest lzma sdk release 9.20 at
http://downloads.sourceforge.net/sevenzip/lzma920.tar.bz2
This generates quite a lot of checkpatch warnings, but I guess we
need to keep the code style as is to avoid a massive job each time we
update this.

There was a mix of UTF-8 and ISO-8859 files in the U-Boot source
tree, which could cause issues with the patchwork review system.
This commit converts all ISO-8859 files to UTF-8.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Now that the other architecture-specific lib directories have been
moved out of the top-level directory there's not much reason to have the
'_generic' suffix on the common lib directory.
