Whatever we were trying to do with LLSharedLibs.cmake hasn't worked on the Mac
for a long time, and trying to fix it only digs up more problems. Skip it:
we've already worked around it.

Update the media_plugins_example CMakeLists.txt to eliminate some CMake
non-existent dependency warnings.

Add back the missing pieces and updated code for the example plugin.  It was useful during testing SLPlugin changes. Not shipped with release versions of viewer

The present CMake logic wants to pass FIXED:NO to the linker for 64-bit
builds, which on the face of it seems like a Good Thing: it permits code to be
relocated in memory, preventing collisions if two libraries happen to want to
load into overlapping address ranges.

However the way it's being specified is wrong and harmful. Passing /FIXED:NO
to the compiler command line engages /FI (Forced Include!) of a nonexistent
file XED:NO -- producing lots of baffling fatal compile errors.

Thanks Callum for diagnosing this!

autobuild 1.1 now supports expanding $variables within a config file --
support that was explicitly added to address this very problem. So now the
windows platform in autobuild.xml uses $AUTOBUILD_ADDRSIZE,
$AUTOBUILD_WIN_VSPLATFORM and $AUTOBUILD_WIN_CMAKE_GEN, which should handle
most of the deltas between the windows platform and windows64.

This permits removing the windows64 platform definition from autobuild.xml.

The one remaining delta between the windows64 and windows platform definitions
was -DLL_64BIT_BUILD=TRUE. But we can handle that instead by checking
ADDRESS_SIZE. Change all existing references to WORD_SIZE to ADDRESS_SIZE
instead, and set ADDRESS_SIZE to $AUTOBUILD_ADDRSIZE. Change the one existing
LL_64BIT_BUILD reference to test (ADDRESS_SIZE EQUAL 64) instead.

fix files that do not end with a newline (warn-on-failure:copyright because some have both problems...)

Formatting, cleanup, and one minor change by Techwolf Lupindo.
Minor change was a move of the hunk in
indra/media_plugins/webkit/CmakeLists.txt to same area as the other plugins CmakeLists.txt files.

daggyfied version of https://bitbucket.org/Techwolf/viewer-development/changeset/00bd21962052

Added an "init" message in LLPLUGIN_MESSAGE_CLASS_MEDIA, and made LLPluginClassMedia queue it up before initializing its LLPluginProcessParent.
Made all existing plugins send their texture_params message from this init message instead of the LLPLUGIN_MESSAGE_CLASS_BASE "init" message.  (This ensures that they won't start to receive 'size_change' messages until after the init has happened.)
Added "set_user_data_path" and "set_language_code" messages to LLPluginClassMedia.
Made webkit plugin deal with the new messages, when they're sent before it receives the media "init".
Removed the user_data_path and language_code arguments from the init function calls throughout the hierarchy.
Made LLViewerMediaImpl queue up the language code and user data path messages before initializing the media.
