topology: Add support for vendor tuples

From: Mengdong Lin <[email protected]>

This series addes support for vendor tuples to topology, to avoid importing binary data blob from other files.

Backward compatibility of ABI is not impacted. A kernel patch is also submitted "ASoC: topology: ABI - Define types for vendor tuples".

The 1st patch is small code cleanup.
The 2nd patch is a preparation, since tuples will need the type-specific free handler.

History:
v2: add check on string length, use strtol() to get hex value,
and fix memory leak.
v3: Fix overflow on uuid string copy. Use strtoul() to get unsigned
vendor values and check range, tested on 32 & 64 bit systems.

Mengdong Lin (7):
topology: Use the generic pointer to free an element's object
topology: Define a free handler for the element
topology: Add doc for vendor tuples
topology: ABI - Define types for vendor tuples
topology: Add support for vendor tokens
topology: Add support for parsing vendor tuples
topology: Build data objects with tuples
