There are certain pieces of NeuralNetworks.h and of our various *.hal
files that ought to be kept in sync -- most notably the operand type
and operation type definitions and descriptions in our
NeuralNetworks.h and types.hal files. To avoid having to do this
manually, a tool can be employed.
The old solution to this problem is sync_enums_to_hal.py, which parses
the existing NeuralNetworks.h and types.hal files, and then rewrites
the types.hal files: It identifies the operand type and operation type
portions of the files, and in the types.hal files replaces them with
transformed versions of the portions from NeuralNetworks.h. This
approach is brittle -- it is very sensitive to the structure of the
files, as was recognized when this tool was created. Changes to those
files since the script was last updated essentially broke the script,
as noted in http://b/140132458.
The new solution employs a new tool generate_api.py to combine a
single "specification file" with one "template file" per API file
(NeuralNetworks.h or types.hal) to produce that API file. The script
generate_api.sh invokes generate_api.py once per API file, passing
appropriate arguments. See frameworks/ml/nn/tools/api/README.md for
more details.
In the process of combining information from NeuralNetworks.h and
*/types.hal, some formatting, syntactic, and semantic changes have
been made to those files. For example:
- types.hal files no longer refer to API levels or (similarly)
to HAL versions other than earlier HAL versions

During the transition to Treble, "device connect" / "disconnect"
parameter was erroneously attributed to audio streams. This
issue got fixed in Audio HAL V4.0, but AudioParameter file
was still using incorrect name for the constant.

Distinguish between internal and external displays, to obviate assuming
that the first display is internal and subsequent displays are external.
Note that connector types (e.g. DSI, HDMI, DisplayPort) are not enumerated,
since that information is irrelevant for internal connections, and can be
extracted from the EDID for external connections in the few cases where it
matters, e.g. gating features like daisy chaining and content protection.

Update the documentation of NetworkScanRequest to clarify
that the interval between scans is from the completion of
one scan to the start of another. This is the only possible
definition that doesn't possibly result in back-to-back
scans which never complete.
In the initial design of this API, the stated use case was
for scans where "interval" >> "scan duration". For that
use case, this clarification doesn't make a meaningful
difference; however, for the use case of long-duration
scans, the distinction prevents the issue stated above.
