2aac8e5dde Further fixes to universal variable server socket management 
- Change fishd_path to std::string
- Warn, rather than exiting with an error, if the universal variable
  server path is not available, and provide more useful advice.
- Export the new __fishd_runtime_dir variable.

209d8b7f2f Fix for CVE-2014-2905 - fishd restart required. 
- Use a secure path for sockets (some code used under license from
   tmux).
 - Provide the secure path in the environment as $__fish_runtime_dir.
 - Link the new path to the old path to ease migration from earlier
   versions.

Closes #1359.

After installing fish built from or after this commit, you MUST
terminate all running fishd processes (`killall fishd`, `pkill fishd`
or similar). Distributors are encouraged to do this from within their
packaging scripts. fishd will restart automatically, and no data should
be lost.

26663e042f Revert "Check effective credentials of socket peers" 
This reverts commit aea9ad4965.

Just checking the credentials of the peer turns out to be
insufficient.
See https://github.com/fish-shell/fish-shell/issues/1436.

aaa0c25ff7 Large set of changes to how PATH is handled. Changed fish to no longer modify PATH in share/config.fish. Introduced variable fish_user_paths, and a glue function __fish_reconstruct_path that splices together PATH with fish_user_paths. Changed fish to no longer validate changes to PATH unless the paths are new (i.e. don't recheck what's already there). Modified certain sets to store const wchar_t instead of wcstring to save a few allocations.
