replace llinfos, lldebugs, etc with new LL_INFOS(), LL_DEBUGS(), etc.

Checker: FORWARD_NULL
Function: LLLocalTextureObject::LLLocalTextureObject(const LLLocalTextureObject&)
File: /indra/newview/lllocaltextureobject.cpp

not a bug.

Checker: UNINIT_CTOR
Function: LLLocalTextureObject::LLLocalTextureObject(LLViewerFetchedTexture *, const LLUUID &)
File: /indra/newview/lllocaltextureobject.cpp

an explicit include for LLViewerFetchedTexture because it's used for
a template specialization, and fixed LLLocalTextureObject constructor
to take a const LLUUID reference so locals can be passed.

No expected functionality change; this mostly contains cosmetic cleanup.

merging in new wearable infrastructure to get a step closer to eventually supporting multiple wearables per type. Merge tested and compiles/working on linux and windows - no obvious regressions on appearance or appearance editor. Merge generated no conflicts due to being tested in fresh re-branch in avatar-pipeline/multiple-textures-12. Merge perfomed with following command:

svn merge -r 136489:136510 svn+ssh://svn.lindenlab.com/svn/linden/branches/avatar-pipeline/multiple-textures-12 .

Progress can be tracked in DEV-32551.
