6e9617371f win32: only use dllexport when building DLL 
If building a static library, marking symbols as dllexport causes them
to be exported from the final executable. For example, run
objdump -x opus_demo.exe on a --disabled-shared build and look for the
export table; there should not be one in a normal Win32 .exe file, but
when linking static libopus, the exe exports all of the opus_* public
functions.

Use the libtool-defined DLL_EXPORT flag to determine whether we are
building a DLL and only specify __declspec(dllexport) in that case.

811dc74204 Suggest OPUS_LSB_DEPTH(14) for G.711. r=td-linux,mark4o 
This is a reasonable choice for the (non-linear) dynamic
range of mu-law. A-law is technically 13 bit, maybe 12;
experimentation is needed.

Per irc discussion with Jean-Marc, Ron, and Mark Harris.

7830cf1bd2 Replace "inline" with OPUS_INLINE. 
Newer versions of MSVC are unhappy with the strategy of the build
 environment redefining "inline" (even though they don't support the
 actual keyword). Instead we define OPUS_INLINE to the right thing
 in opus_defines.h.

This is the same approach we use for restrict.
