restore the ll[io]fstream because we need them as wrappers on Windows for wide char paths; on other platforms they are now just typedefs to the std classes

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

consolidated most indra-specific constants in llcommon under indra_constants.h
fixed issues with operations on mixed unit types (implicit and explicit)
made LL_INFOS() style macros variadic in order to subsume other logging methods
such as ll_infos
added optional tag output to error recorders

Checker: UNINIT_CTOR
Function: LLPostProcess::LLPostProcess()

Be careful of future merges involving changes to any of these moved files as SVN usually does the wrong thing:
newview/llglslshader.* -> llrender/llglslshader.*, llrender/llshadermgr.*, newview/llviewershadermgr.* (gets split into 3 separate files)
newview/llpostprocess.* -> llrender/llpostprocess.*
newview/llrendersphere.* -> llrender/llrendersphere.*
newview/llcubemap.* -> llrender/llcubemap.*
llwindow/llgl.* -> llrender/llgl.*
llwindow/llglstates.h -> llrender/llglstates.h
llwindow/llgltypes.h -> llrender/llgltypes.h
llwindow/llglheaders.h -> llrender/llglheaders.h
