Printing the inference output in the inference process is a costly
operation because it converts the data to a base64 string and calculates
a checksum for it. Printing the output can be good for debugging but to
avoid unwanted performance impact, the feature has been put behind a
build flag that is disabled by default.

As TensorFlow Lite Micro is a third party library, declare include

Replace empty log macros with calls to a new LOG_COMMON_NOP macro, with
the intention of avoiding unused variable/parameter warnings where the
variables/parameters are currently only used for logging. The if check
will normally be optimized away.

Change formatting of error messages, prepend the file name and line
instead of appending it, to allow for newlines in error messages.

Add a check for __FILE_NAME__ macro and use that instead of strrchr
function, when available.

Introduce a new CORE_LOG_SEVERITY variable to set the log level desired
for core software/core platform applications. Separating it from the
ETHOSU_LOG_SEVERITY setting that now only affect the core_driver log
level. Add a new CORE_LOG_ENABLE variable that allows all logs
(including the unconditional LOG macro) to be turned off. Note however
that it will not affect printf and similar calls, but only logs going
through the ethosu_log library.

Sync the ethosu_log library with changes from the intended standalone
copy in core_driver.

MakeAvailable, however it's not the case. Add an invalid path to

Currently the profiler uses signed 32-bit integers to hold the start and
end tick values. This is not appropriate because the tick values will
never be negative and the current ticks are returned as an unsigned
32-bit integer value.

To address this, the start and end ticks will now be stored as unsigned
32-bit integers instead.

The OpenAMP library has been changed to required the build system to
define the VIRTIO_DRIVER_SUPPORT and VIRTIO_DEVICE_SUPPORT macros to
know what code to include and will fail to build if these macros are not
defined.

As a custom CMake file is used to build OpenAMP rather than using the
one provided by the library, the library currently fails to build
because the custom CMake file does not define the required macros.

To resolve this, the custom CMake file now defines the missing macros.

The inference parser copies the description from the model using
strncpy, which will only add a null-terminator if the source string is
shorter than the destination. Otherwise, if the bytes copied are not
null-terminated, the destination is left without one.

To ensure that the description is always null-terminated, the last byte
of the description is now always overwritten with one.
