Joe Subbiani d3a3f21ad5 Improve documentation and add more uses of MBEDTLS_PUT
minor changes, such as improving the documentation for the byte reading
macros, and using MBEDTLS_PUT_UINT16_xy in place of byte reading
macro combinations

Joe Subbiani 896f4eeaf7 Improve consitency throughout library/common.h
Replace the contents of MBEDTLS_PUT_UINTx_yz contained inconsitent
but similar/duplicate code to the MBEDTLS_BYTE_x macros. Therefore
the contents of the macros now utilise the byte reading macros.

MBEDTLS_PUT_UINT64_LE's written order was also not consitent with
the other PUT macros, so that was modified.

Documentation comment said LSB instead of MSB and that has also been
resolved.

Joe Subbiani 1bd5d7da82 Add UINT64 GET and PUT macros
Copy over the GET/PUT_UINT64_LE/BE macros from aes.c and sha512.c
Add the MBEDTLS_ prefix to all 4 macros.
Modify the GET_UINT64 macros to no longer take a target variable
as a parameter, so when the macro function is called it must be
assigned to a variable in the same statement.

Joe Subbiani c045dc14b0 Replace MBEDTLS_CHAR_x with MBEDTLS_BYTE_x
The CHAR macros casted to an unsigned char which in this project
is garunteed to be 8 bits - the same as uint8_t (which BYTE casts
to) therefore, instances of CHAR have been swapped with BYTE and
the number of macros have been cut down

Joe Subbiani 6b897c930c Add Character byte reading macros
These cast to an unsigned char rather than a uint8_t
like with MBEDTLS_BYTE_x
These save alot of space and will improve maintence by
replacing the appropriate code with MBEDTLS_CHAR_x

Joe Subbiani 9231d5f919 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
