741ab8ba05 use PyMem_Malloc / Free
Hopefully it is better dealing with a lot of small-object allocations than malloc/free is.
Small allocs happen if the input file is small, so it results only in 1 small chunk.

ee604ab390 crypto: use OpenSSL 1.1 HMAC API
This breaks it on OpenSSL 1.0.x as there is no HMAC_CTX_new/free() yet.

OTOH, this change is consistent with the previous change done for
EVP_CIPHER_CTX (which works on 1.0 and 1.1).

67567fc432 new crypto api, blackbox/AEAD. also adds AES256-GCM.
includes:

- aes256-ctr-hmac-sha256 (attic/borg legacy, optional aad support)

- aes256-gcm (new, optional aad support)
  uses 96bits for iv, 128bit for auth tag.

- header support
  the caller-provided header will be just copied in front of the rest -
  this avoids expensive operations (memcpy, garbage collection) in Python.
  the first bytes in the header may be non-authenticated data if aad_offset > 0.
  this is to support legacy attic/borg envelope layout, where the type byte
  is not authenticated.

- aad support
  additional authenticated data - it just contributes to the computed mac,
  but is not encrypted). the current api assumes that aad starts at some
  aad_offset inside the given header and extends to the end of it.

- iv handling helpers, compute next iv based on amount of processed data

- unit tests

Note: the changes are intentionally kept isolated / not integrated into the
      rest of the code, so this has to be done later.

chunk_incref was called when dealing with part files without giving the
known chunk size in the size_ parameter.

199f192a65 archive: closely wrap next() called from generator
lgtm:
Calling next() in a generator may cause unintended early termination of
an iteration.

It seems that lgtm did not detect the more loose wrapping that we used
before.
