Fix formatting of concatenation example

FeRD (Frank Dana)
872f767fec Fix formatting of concatenation example 
The "Concatenation of .lz4 files" section contains example commands
that are run together on one line, making them invalid. Wrap them
in a code block and clean up surrounding formatting.

6ad3a983db fix #369 
The bug would make the bt search read one byte in an invalid memory region,
and make a branch decision based on its value.
Impact was small (missed compression opportunity).
It only happens in -BD mode, with extDict-prefix overlapping matches.

The bt match search is supposed to work also in extDict mode.
In which case, the match ptr can point into Dict.
When the match was overlapping Dict<->Prefix,
match[matchLength] would end up outside of Dict, in an invalid memory area.
The correction ensures that in such a case,
match[matchLength] ends up at intended location, inside prefix.

e14b4c5a3e tests/Makefile: don't use LIBDIR as variable 
LIBDIR may be overriden with a environment variable: In this case make
clean breaks in tests/. Use another variable name.

89b9f026c9 made level 10 a bit faster 
at the expense of a little bit of compression ratio.

Now speed is intermediate on calgary corpus :
25 - 12 - 8 - 3

a8dd86d93e changed macro HEAPMODE into LZ4_HEAPMODE 
This macro is susceptible to be triggered from user side
typically through compiler flag (-DLZ4_HEAPMODE=1).
In which case, it makes sense to prefix the macro
since we want to reduce potential side-effect on namespace.

clamp hc levels > 12 + minor fixes in comments

6cf1f7d758 lz4hc.c: clamp compression levels > 12 
I noticed that, while 'lz4 -12' works fine, 'lz4 -13' does not compress
at all.

$ cat </etc/passwd |wc -c
2565
$ lz4 -12 </etc/passwd |wc -c
1456
$ lz4 -13 </etc/passwd |wc -c
2584

Perhaps the best way to fix this is to clamp the compression level
in the LZ4HC_compress_generic routine.

e2827775ee make __packed memory access default for gcc 
It's always as good or better then memcpy()
but depends on gcc-specific extension.
