6a50631497 GET macros use a target variable
The GET macros used to write to a macro parameter, but now
they can be used to assign a value to the desired variable
rather than pass it in as an argument and have it modified
in the macro function.

Due to this MBEDTLS_BYTES_TO_U32_LE is the same as
MBEDTLS_GET_UINT32_LE and was there for replaced in the
appropriate files and removed from common.h

5ecac217f0 Prefixed macros with MBEDTLS

54c6134ff7 Move UINT32_LE macros to common.h
32-bit integer manipulation macros (little edian):
GET_UINT32_LE and PUT_UINT32_LE appear in several
files in library/.
Removes duplicate code and save vertical
space the macro has been moved to common.h.
Improves maintainability.

Also provided brief comment in common.h for
BYTES_TO_U32_LE. comment/documentation will
probably need to be edited further for all
recent additions to library/common.h

12e18369e8 aes: Check aes_padlock_ace > 0 before calling padlock
Sometime user may forget to call mbedtls_aes_setkey_enc or
mbedtls_aes_setkey_dec before mbedtls_aes_crypt_ecb and then
the code normally crash inside the assembly code. With this
patch, the code will stop inside the C source code which is
more convenient to locate the problem.

Make the aes xts methods independent from MBEDTLS_AES_SETKEY_DEC_ALT
This is fix for the MBEDTLS_AES_SETKEY_DEC_ALT macro switch is including the aes xts methods
and building with a custom mbedtls_aes_setkey_dec function will disable the aes xts methods.
The fix is separating the aes xts methods and the MBEDTLS_AES_SETKEY_DEC_ALT can only
switch the presence of the mbedtls_aes_setkey_dec function.

5197c6692c Put local variables in a struct
This way we can have a single call to mbedtls_platform_zeroize, which
saves a few bytes of code size.

Additionally, on my PC, I notice a significant speed improvement
(x86_64 build with MBEDTLS_AESNI_C disabled, gcc 5.4.0 -O3). I don't
have an explanation for that (I expected no measurable difference).

ee4d4eb625 Remove a useless zeroization
Remove the zeroization of a pointer variable in the AES block
functions. The code was valid but spurious and misleading since it
looked like a mistaken attempt to zeroize the pointed-to buffer.
Reported by Antonio de la Piedra, CEA Leti, France.

Note that we do not zeroize the buffer here because these are the
round keys, and they need to stay until all the blocks are processed.
They will be zeroized in mbedtls_aes_free().

96ae5cd087 Zeroize local AES variables before exiting the function
This issue has been reported by Tuba Yavuz, Farhaan Fowze, Ken (Yihang) Bai,
Grant Hernandez, and Kevin Butler (University of Florida) and
Dave Tian (Purdue University).

In AES encrypt and decrypt some variables were left on the stack. The value
of these variables can be used to recover the last round key. To follow best
practice and to limit the impact of buffer overread vulnerabilities (like
Heartbleed) we need to zeroize them before exiting the function.

- It adds uses of the `do { ... } while( 0 )` idiom for macros that
  can be used as commands.

5f77801ac3 Implement AES-XTS mode
XTS mode is fully known as "xor-encrypt-xor with ciphertext-stealing".
This is the generalization of the XEX mode.
This implementation is limited to an 8-bits (1 byte) boundary, which
doesn't seem to be what was thought considering some test vectors [1].

This commit comes with tests, extracted from [1], and benchmarks.
Although, benchmarks aren't really nice here, as they work with a buffer
of a multiple of 16 bytes, which isn't a challenge for XTS compared to
XEX.

f5bf7189d3 Change return type of AES decrypt and encrypt
This patch modifies the following 2 functions in the AES module to
change the return type from void to int:
    * mbedtls_aes_encrypt() -> mbedtls_internal_aes_encrypt()
    * mbedtls_aes_decrypt() -> mbedtls_internal_aes_decrypt()
This change is necessary to allow users of MBEDTLS_AES_ALT,
MBEDTLS_AES_DECRYPT_ALT and MBEDTLS_AES_ENCRYPT_ALT to return an error
code when replacing the default with their own implementation, e.g.
a hardware crypto accelerator.

This commit fixes following warning:

> CC:  aes.c
> aes.c: In function 'mbedtls_aes_self_test':
> aes.c:1225:19: error: unused variable 'iv' [-Werror=unused-variable]
>      unsigned char iv[16];
>                    ^
> cc1: all warnings being treated as errors

algorithm context structure and all 'core' functions.
