295fc13ef3 Split mbedtls_gcm_update_ad out of mbedtls_gcm_starts
The GCM interface now has separate functions to start the operation
and to pass the associated data.

This is in preparation for allowing the associated data to be passed
in chunks with repeatated calls to mbedtls_gcm_update_ad().

a56c448636 Add output length parameters to mbedtls_gcm_update
Alternative implementations of GCM may delay the output of partial
blocks from mbedtls_gcm_update(). Add an output length parameter to
mbedtls_gcm_update() to allow such implementations to delay the output
of partial blocks. With the software implementation, there is no such
delay.

9461e45a17 Add output parameter to mbedtls_gcm_finish
Alternative implementations of GCM may delay the output of partial
blocks from mbedtls_gcm_update(). Add an output parameter to
mbedtls_gcm_finish() to allow such implementations to pass the final
partial block back to the caller. With the software implementation,
this final output is always empty.

58fc272af9 Remove alignment requirement for mbedtls_gcm_update: implementation
mbedtls_gcm_update now accepts inputs of arbitrary size. There is no
longer a requirement that all calls except the last one pass a
multiple of 16 bytes.

This commit updates the library code and adjusts the GCM tests to
exercise arbitrarily aligned input sizes.

187782f41e Move aesni.h to library
`aesni.h` is an internal header and is moved accordingly.

Also removes some references to internal headers in scripts with
only public headers.

1e14827beb Update copyright notices to use Linux Foundation guidance
As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the

db09ef6d22 Include common.h instead of config.h in library source files
In library source files, include "common.h", which takes care of
including "mbedtls/config.h" (or the alternative MBEDTLS_CONFIG_FILE)
and other things that are used throughout the library.

2a078da134 Run AES-GCM-192 selftest if available only
This patch modifies the function mbedtls_gcm_self_test() function to
ensure that AES-GCM-192 tests are only run if the key size is supported
by the available implementation. This is useful when using
MBEDTLS_AES_ALT as some hardware crypto accelerators might not support
AES-192.

1e07562da4 Fix wrong length limit in GCM
See for example page 8 of
http://csrc.nist.gov/publications/nistpubs/800-38D/SP-800-38D.pdf

The previous constant probably came from a typo as it was 2^26 - 2^5 instead
of 2^36 - 2^5. Clearly the intention was to allow for a constant bigger than
2^32 as the ull suffix and cast to uint64_t show.

fixes #362
