Update Cython string types (#9143) * Replace all basestring references with unicode `basestring` was a compatability type introduced by Cython to make dealing with utf-8 strings in Python2 easier. In Python3 it is equivalent to the unicode (or str) type. I replaced all references to basestring with unicode, since that was used elsewhere, but we could also just replace them with str, which shoudl also be equivalent. All tests pass locally. * Replace all references to unicode type with str Since we only support python3 this is simpler. * Remove all references to unicode type This removes all references to the unicode type across the codebase and replaces them with `str`, which makes it more drastic than the prior commits. In order to make this work importing `unicode_literals` had to be removed, and one explicit unicode literal also had to be removed (it is unclear why this is necessary in Cython with language level 3, but without doing it there were errors about implicit conversion). When `unicode` is used as a type in comments it was also edited to be `str`. Additionally `coding: utf8` headers were removed from a few files.

Support 'memory zones' for user memory management (#13621) Add a context manage nlp.memory_zone(), which will begin memory_zone() blocks on the vocab, string store, and potentially other components. Example usage: ``` with nlp.memory_zone(): for text in nlp.pipe(texts): do_something(doc) # do_something(doc) <-- Invalid ``` Once the memory_zone() block expires, spaCy will free any shared resources that were allocated for the text-processing that occurred within the memory_zone. If you create Doc objects within a memory zone, it's invalid to access them once the memory zone is expired. The purpose of this is that spaCy creates and stores Lexeme objects in the Vocab that can be shared between multiple Doc objects. It also interns strings. Normally, spaCy can't know when all Doc objects using a Lexeme are out-of-scope, so new Lexemes accumulate in the vocab, causing memory pressure. Memory zones solve this problem by telling spaCy "okay none of the documents allocated within this block will be accessed again". This lets spaCy free all new Lexeme objects and other data that were created during the block. The mechanism is general, so memory_zone() context managers can be added to other components that could benefit from them, e.g. pipeline components. I experimented with adding memory zone support to the tokenizer as well, for its cache. However, this seems unnecessarily complicated. It makes more sense to just stick a limit on the cache size. This lets spaCy benefit from the efficiency advantage of the cache better, because we can maintain a (bounded) cache even if only small batches of documents are being processed.
