SE API: hide private interfaces

- Split each headers into module.h and module_priv.h, move the methods that
is only used internally by SE implementation to module_priv.h, and export
module_priv.h to rest of TEE Core
- Added new include path to se_api_self_tests.c for which needs to include
private headers
- Split aid.c and apdu.c from iso7816.c. Originally they have to be wriiten in
the same file since they share some private data structures. Now, the
private data structure can be shared via private headers.
- Split reader.c from manager.c for the same reason above.

Add PKCS #5 v2.0 key derivation function 2 (PBKDF2)

This commit implements a crypto extension to support the key derivation
function defined in section 5.2 of RFC 2898
(https://www.ietf.org/rfc/rfc2898.txt), which is a re-publish of PKCS #5 v2.0.
The underlying pseudorandom function is HMAC-SHA1, which is the default PRF
specified in the RFC. It would be trivial to support the other HMAC functions
already implemented in OP-TEE.

See documentation/extensions/crypto_pbkdf2.md for details.

Tested on PLATFORM=vexpress-qemu_virt with the test vectors from RFC 6070
(https://www.ietf.org/rfc/rfc6070.txt).

Add HMAC-based extract-and-expand key derivation function (HKDF)

HKDF (http://tools.ietf.org/html/rfc5869) is a key derivation algorithm.
As per the RFC:

A key derivation function (KDF) is a basic and essential component of
cryptographic systems. Its goal is to take some source of initial
keying material and derive from it one or more cryptographically
strong secret keys.
[...]
HKDF follows the "extract-then-expand" paradigm, where the KDF
logically consists of two modules.
[...]
The goal of the "extract" stage is to "concentrate" the possibly
dispersed entropy of the input keying material into a short, but
cryptographically strong, pseudorandom key.
[...]
The second stage "expands" the pseudorandom key to the desired
length; the number and lengths of the output keys depend on the
specific cryptographic algorithms for which the keys are needed.

Since HKDF is not covered by the GlobalPlatform Internal API specification
v1.0/v1.1, this commit introduces extensions to the specification.
More specifically: it defines new algorithms, a new object type and new
object attributes. This implementation supports all the usual hash
functions (MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512) and may
produce output keys of length up to 4096 bits (currently limited only by
the maximum size allowed for an object of type TEE_TYPE_GENERIC_SECRET).
Aside from minor updates to object manipulation functions to support
the new data, the function TEE_DeriveKey() is mostly impacted.

The file documentation/extensions/crypto_hkdf.md contains the modifications
to the GP Internal API v1.0 spec in order to support HKDF.

(http://csrc.nist.gov/publications/nistpubs/800-56A/SP800-56A_Revision1_Mar08-2007.pdf)

This is a TEE implementation of the function, which supports the following
hash algorithms: SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512.
The actual key derivation is implemented in TEE_DeriveKey() thanks to
custom extensions to the GlobalPlatform API v1.0. Please refer to
documentation/extensions/crypto_concat_kdf.md for details.
