The util component specified fnv and smallvec as dependencies and publicly
reexported both of them. Several other components utilized these reexports,
presumably because fnv and smallvec used to live in the tree so reexporting
made the transition easier.
These indirect dependencies through the util component are unnecessary.
This commit removes the fnv & smallvec crate reexports in the util component.
It exchange, it adds fnv & smallvec as dependencies to non-util components
wherever needed. Finally, it removes the fnv dependency from util as it is not
utilized anywhere in the util component.
This uses some dependencies from crates.io instead of git
where the crates.io copy was already used in some other part
of the dependency tree, so we had two copies of the same library.
The `android_glue` crate is the only one left where we have two copies,
but solving that is more tricky since we hard-code a path in
`components/servo/.cargo/config`.
- Most of util::memory has been moved into profile::mem, though the
`SizeOf` trait and related things remain in util::memory. The
`SystemMemoryReporter` code is now in a submodule
profile::mem::system_reporter.
- util::time has been moved entirely into profile::time.
It should replace `match foo.to_ascii_lower().as_slice() { ...}`
@Manishearth I changed map.get to map.find in the lint to work around an ICE:
task 'rustc' panicked at 'couldn't find node id 0 in the AST map'
Does this look OK?
