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.

dab3590fce Export deprecated symbols declared in lz4hc.h 
Commit 25b2435885 exported deprecated
symbols declared in lz4.h by marking all LZ4_DEPRECATED functions with
LZ4LIB_API attribute.  This change does the same with functions declared
in lz4hc.h file, thus extending the export to lz4hc.h.

As result, the following 17 deprecated functions are exported again:

LZ4_compressHC
LZ4_compressHC2
LZ4_compressHC2_continue
LZ4_compressHC2_limitedOutput
LZ4_compressHC2_limitedOutput_continue
LZ4_compressHC2_limitedOutput_withStateHC
LZ4_compressHC2_withStateHC
LZ4_compressHC_continue
LZ4_compressHC_limitedOutput
LZ4_compressHC_limitedOutput_continue
LZ4_compressHC_limitedOutput_withStateHC
LZ4_compressHC_withStateHC
LZ4_createHC
LZ4_freeHC
LZ4_resetStreamStateHC
LZ4_sizeofStreamStateHC
LZ4_slideInputBufferHC

b1daffc4e5 cli: add GNU separator -- specifying that all following arguments are files 
This option is supported by other compressors with compatible cli,
so add it to lz4 as well for better compatibility.

aae447fffd LZ4_compress_HC_continue_destSize() works as intended up to level 10 
It's incompatible with btopt though,
so cLevel >= 11 feature much reduced performance (degraded mode)

cd35f0d98c LZ4_compress_HC_destSize() uses LZ4HC_compress_generic() code path 
Limits compression level to 10,
to remain compatible with Hash Chain.
