Summary: ProcFileReader is the cause of the dependency from Host to ProcessLinux module. Since it's interface is also obsolete (ReadIntoDataBuffer is trivially replaceable by llvm::MemoryBuffer functions and ProcessLineByLine is trivially implementable with StringRefs), instead of moving it around I'm planning to obliterate it. This is the first step, where I remove a couple of occurences in linux/Host.cpp, and modernize some code around that. I have introduced linux/Support.h, which holds two utility functions now, whose resposibility is to construct the appropriate proc file names -- the only useful feature of ProcFileReader. I add a couple of tests for these functions, and for Host::GetProcessInfo. It's worth noting that these are the first host-specific unit tests in lldb.
