1. std: Stabilize a number of new fs features …

   This commit stabilizes the following APIs, slating them all to be cherry-picked
   into the 1.1 release.
   
   * fs::FileType (and transitively the derived trait implementations)
   * fs::Metadata::file_type
   * fs::FileType::is_dir
   * fs::FileType::is_file
   * fs::FileType::is_symlink
   * fs::DirEntry::metadata
   * fs::DirEntry::file_type
   * fs::DirEntry::file_name
   * fs::set_permissions
   * fs::symlink_metadata
   * os::raw::{self, *}
   * os::{android, bitrig, linux, ...}::raw::{self, *}
   * os::{android, bitrig, linux, ...}::fs::MetadataExt
   * os::{android, bitrig, linux, ...}::fs::MetadataExt::as_raw_stat
   * os::unix::fs::PermissionsExt
   * os::unix::fs::PermissionsExt::mode
   * os::unix::fs::PermissionsExt::set_mode
   * os::unix::fs::PermissionsExt::from_mode
   * os::unix::fs::OpenOptionsExt
   * os::unix::fs::OpenOptionsExt::mode
   * os::unix::fs::DirEntryExt
   * os::unix::fs::DirEntryExt::ino
   * os::windows::fs::MetadataExt
   * os::windows::fs::MetadataExt::file_attributes
   * os::windows::fs::MetadataExt::creation_time
   * os::windows::fs::MetadataExt::last_access_time
   * os::windows::fs::MetadataExt::last_write_time
   * os::windows::fs::MetadataExt::file_size
   
   The `os::unix::fs::Metadata` structure was also removed entirely, moving all of
   its associated methods into the `os::unix::fs::MetadataExt` trait instead. The
   methods are all marked as `#[stable]` still.
   
   As some minor cleanup, some deprecated and unstable fs apis were also removed:
   
   * File::path
   * Metadata::accessed
   * Metadata::modified
   
   Features that were explicitly left unstable include:
   
   * fs::WalkDir - the semantics of this were not considered in the recent fs
     expansion RFC.
   * fs::DirBuilder - it's still not 100% clear if the naming is right here and if
     the set of functionality exposed is appropriate.
   * fs::canonicalize - the implementation on Windows here is specifically in
     question as it always returns a verbatim path. Additionally the Unix
     implementation is susceptible to buffer overflows on long paths unfortunately.
   * fs::PathExt - as this is just a convenience trait, it is not stabilized at
     this time.
   * fs::set_file_times - this funciton is still waiting on a time abstraction.
