make __packed memory access default for gcc

It's always as good or better then memcpy()
but depends on gcc-specific extension.

Export only those symbols that are part of public API

Specify -fvisibility=hidden parameter when linking the shared library
using -fPIC, assuming that gcc >= 4 is used.

Export deprecated symbols
...
Deprecated symbols are still a part of ABI and have to be exported,
so mark them with LZ4LIB_API attribute.

Explicitly set visibility of public API functions when gcc is used
...
Windows builds already limit exporting of functions to those marked
with LZ4LIB_API tag. The same behaviour could be achieved on other
platforms when a relatively fresh gcc is used.
This change assigns public visibility to all symbols marked with
LZ4LIB_API tag. When the library is built in -fvisibility=hidden
mode, only these marked symbols will be exported.
