This reverts commit 9abbf010.

As commentted in https://github.com/tikv/rust-rocksdb/pull/442#issuecomment-595001970, `PerfContext` is naturally `!Send` because it contains a raw pointer.

Reverting #442 makes this crate compile on stable Rust.

fix tikv/tikv#6973

As mentioned in the linked issue, the aim is to implement `!Send` for the `PerfContext` struct.
Although the issue is related to the `tikv/tikv` repo, the concerned `PerfContext` is taken from this repo. 
Due to the rule that "foreign traits can't be implemented on foreign types", it isn't possible to directly implement the `!Send` trait on the `PerfContext` struct. So, either I had to enclose the `PerfContext` within another type and implement `!Send` for the new type (along with implementing all the functions present for `PerfContext`), or directly add the `!Send` implementation, where the struct is defined, i.e, in this repo.  I've taken the second path.
but, there is a problem. `impl !Send` is currently only supported in nightly and not on stable channel.
So, it's necessary to build this crate with nightly toolchain, if this patch is accepted.
