Factored out Linux proc file reading into separate class.
Both NativeProcessLinux (in llgs branch) and Linux Host.cpp had similar code to handle /proc
file reading. I factored that out into a new Linux-specific ProcFileReader class and added a method
that the llgs branch will use for line-by-line parsing.
This change also adds numerous Linux-specific files to Xcode that were missing from the Xcode
project files.
