Joe Subbiani ad1115a3fd Use byte reading macros in places not using a byte mask 
byte shifting opertations throughout library/ were only replaced with
the byte reading macros when an 0xff mask was being used.
The byte reading macros are now more widley used, however they have not
been used in all cases of a byte shift operation, as it detracted from
the immediate readability or otherwise did not seem appropriate.

Paul Elliott 88f2eb664f Remove multiplication from conditional assignments 
Multiplication is not constant flow on any CPU we are generally
targetting, so replace this with bit twiddling.

Bence Szépkúti 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

Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

Gilles Peskine 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.

Andres AG 4623d83c6f Fix integer overflow mbedtls_base64_decode() 
Fix potential integer overflows in the function mbedtls_base64_decode().

cause buffer bound checks to be bypassed.
