[PATCH v2 07/10] a2dp-codecs: Add needed includes and properly check for endian macros

[Pali Rohár <pali.rohar@xxxxxxxxx>]

Without stdint.h type uint8_t cannot be used.

And without endian.h macros __BYTE_ORDER, __LITTLE_ENDIAN and __BIG_ENDIAN
are not defined.

When both __BYTE_ORDER and __LITTLE_ENDIAN macros are not defined, then
condition #if __BYTE_ORDER == __LITTLE_ENDIAN is true.
