Fleshed out target_link_libraries dependencies between libraries.  Appearance utility now reads avatar_lad.xml during stubbed out params processing.

EXT-7005 : Kill unhelpful 'Deprecated conversion from string to char *' warnings from fmod_errors.h when building with GCC >=4.2 on Darwin

Apply -Wno-write-strings compile flag to llaudioengine_fmod.cpp and llstreamingaudio_fmod.cpp on Darwin as it was on Linux (Amen).
Removed unnecessary check for GCC >= 4.2 when applying this flag, as CXX_VERSION_NUMBER it used is only being generated in 00-Common.cmake on Linux at the moment and 4.0 understands -Wno-write-strings anyway.

CMakeFiles.txt file. Previously it checked for a narrow range of gcc
versions via a regex:

      if (${CXX_VERSION} MATCHES "4.[23]")

Now we explicit check for any version >= 4.2:

      if (${CXX_VERSION_NUMBER} GREATER 419)

at some point someone inlined this into llaudiodecodemgr and the 'indie' version rotted away.

- Updated linux_updater for new LLStringUtil::getTokens() signature
- Ignore compiler warning for string constants not being referred to
  as const in fmod_error.h

Fix for DEV-39457. Reviewed by moss.

Some branch shenannigans in the pluginapi_05 branch caused this to become a two-part merge.

Check the actual version of the compiler we're going to use to compile the sources to determine which options need to be added rather than the version of some other compiler on the system.
