When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.
--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
file operations will be abstracted in the future for the reproduction mechanism.
FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

on the presence of a 'clang' executable. Simplify
CIndexer::getClangResourcesPath() a bit.
Patch up the CMake makefiles to install headers into two locations in
the build tree, for those silly cases where 'clang' will end up
looking into the wrong build directory for headers.

improvements to the compiler and the introduction of crash recovery,
it no longer makes sense to allow this mode. Moreover, this eliminates
one use of the "clang" executable from within libclang; we'd like them
all to go away.
