daf7045372 Add benchmark for AES-XEX 
This commit adds benchmark based on what has already been done with
AES-CBC mode.

9bbe3632e4 Rename exported symbols to please check-names.sh 
Exported symbols seem to need the "mbedtls_" prefix, which has been
added to be128 and gf128mul_x_ble.

fb67fae83a Add AES-XEX tests cases 
The test cases come from the XTS test vectors given by the CAVP initiative
from NIST (see [1]).
As mentioned in a previous commit, XEX is a simpler case of XTS.
Therefore, to construct the test_suite_aes.xex.data file, extraction of
the XEX-possible cases has been done on the given test vectors.
All of the extracted test vectors pass the tests on a Linux x86_64 machine.

75e3661ebe Add AES-XEX mode to the default config file 
Adding the AES-XEX mode to the default config file permits this mode to
be compiled, and tested, which may be needed for some programs in the
future.

0089d36ae5 Implement AES-XEX mode 
XEX mode, known as "xor-encrypt-xor", is the simple case of the XTS
mode, known as "XEX with ciphertext stealing". When the buffers to be
encrypted/decrypted have a length divisible by the length of a standard
AES block (16), XTS is exactly like XEX.

b053658f95 Add 2 files for multiplication in GF(128) 
Multiplication in GF(128) is required by the AES-XEX mode for computing
X in the XEX formula from

80f679b938 Correct and clarify the documentation of GCM whole-message functions 
Clarify the roles of the buffer parameter and their sizes.

Remove a statement about input size restrictions that only applies to
mbedtls_gcm_update, not to the whole-message functions.

Document the possible error codes.

Warn that mbedtls_gcm_crypt_and_tag in decrypt mode does not
authenticate the data and recommend using mbedtls_gcm_auth_decrypt
instead.
