Fixed coding standard error in several files. Use of while( is incorrect; a space is required between while and (. Also ran tools/nxstyle and fix thoses complaints as well in most files.
Changes to comply with coding standard. Mostly focused on files with missing space after keyword in if(, switch(, and for(. Offending files also got changes to comply with tools nxstyle. If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh. Still need to fix occurrences of while( with missing space. There are a lot of them.
Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.
