Summary:
This diff updates all license headers to use the new text and style.
Also, a few internal files were missing the header, but now they have it.
`fbcode/common/rust/netstring/` had the internal header, but now it has
GPLV2PLUS - since that goes to Mononoke's Github too.

Summary:
This diff moves initFacebook calls that used to happen just before FFI calls to instead happen at the beginning of main.
The basic assumption of initFacebook is that it happens at the beginning of main before there are additional threads. It must be allowed to modify process-global state like env vars or gflags without the possibility of a data race from other code concurrently reading those things. As such, the previous approach of calling initFacebook through `*fbinit::FACEBOOK` near FFI calls was prone to race conditions.
The new approach is based on attribute macros added in D17245802.
---
The primary remaining situations that still require `*fbinit::FACEBOOK` are when we don't directly control the function arguments surrounding the call to C++, such as in lazy_static:
lazy_static! {
static ref S: Ty = {
let _ = *fbinit::FACEBOOK;
/* call C++ */
};
}
and quickcheck:
quickcheck! {
fn f(/* args that impl Arbitrary */) {
let _ = *fbinit::FACEBOOK;
/* call C++ */
}
}
I will revisit these in a separate diff. They are a small fraction of total uses of fbinit.

Summary:
`extern crate` is usually no longer needed in 2018 edition of Rust. This diff removes `extern crate` lines from fbcode where possible, replacing #[macro_use] with individual import of macros.
Before:
```
#[macro_use]
extern crate futures_ext;
extern crate serde_json;
```
After:
```
use futures_ext::try_boxfuture;
```

Summary:
We now have two Manifest and two Entry traits and it makes it very confusing.
The old Manifest trait (and related EmptyManifest struct and Entry trait) are
mercurial-specific, while new Manifest trait is generic over all kinds of
manifests (unodes, mercurial etc).
In ideal state we should have only new Manifest trait, but it'd require quite a
big refactoring. In short term let's at least rename Manifest to HgManifest and
Entry to HgEntry to make distinction clearer.

Summary: `HgEntryId` is much more useful in a typed from (enum of `(FileType, HgFileNodeId)` and `HgManifestId`), most of the time we now which type entry should contain and it makes it harder to make and error, all other use cases which require just hash should use `HgNodeHash` instead. This diff includes minimal changes which are necessary to make it work. Some of the cases which do sequence of `Entry::get_hash().into_nondehash() -> HgManifestId::new() | HgFileNodeId::new()` are left for future diffs.
