Bear needs to canonicalise file paths

[nickhutchinson]

Bear currently doesn't resolve relative path components for the file key in each compilation entry. So if you invoke Bear with something like the following:
bear -- sh -c "gcc /home/nick/foo/bar/../../fee.c", you get a compilation database entry like:

{
  "directory": "/home/nick",
  "command": "gcc /home/nick/foo/bar/../../fee.c",
  "file": "/home/nick/foo/bar/../../fee.c"
}

This is a problem, because when you feed a compilation database to libclang's CXCompilationDatabase, it doesn't canonicalise these paths for you. (At least not with LLVM 3.4.) If you ask it for the flags for /home/nick/fee.c, it won't return any results.

Thanks for this report. Gonna fix when I'm back from vacation.
