use C linkage where appropriate in headers

Assure that 'extern "C" { /../ }' do not cover files included from a
particular header file, and address minor issues resulting from this
change of order.

Dealing with C++ should delegate to the individual include file level,
rather than being imposed by the user of that file. For example,
forcing C linkage prevents __Generic macros being replaced with
overloaded static inline functions in C++ translation units.

Eliminate 'extern "C"' from files which do not declare any symbols
(e.g., only macros or struct types).

On the other hand, the headers check is too naive in assuming that all
headers must contain a 'extern "C"'. Such a check was added in commit
1ee492bdc4ff ("buildtools/chkincs: check missing C++ guards").
Since this current change results in many headers not containing such
a token, remove the check for 'extern "C"' until we have a better
implementation.

graph: fix mcore dispatch walk

Head move happens before the core id check, which will cause the last
source node be executed even core id is not correct. This patch changes
head check to less than 1

head check to less than 1 instead of 0 to fix this issue.

graph: introduce graph walk by cross-core dispatch

This patch introduces the task scheduler mechanism to enable dispatching
tasks to another worker cores. Currently, there is only a local work
queue for one graph to walk. We introduce a scheduler worker queue in
each worker core for dispatching tasks. It will perform the walk on
scheduler work queue first, then handle the local work queue.
