[PATCH v4 1/7] eal: fix header build with C++

[Bruce Richardson]

C++ files could not include some headers because:

* "new" is a keyword in C++, so can't be a variable name
* there is no automatic casting to/from void *

Fixes: 184104fc6121 ("ticketlock: introduce fair ticket based locking")
Fixes: 032a7e5499a0 ("trace: implement provider payload")
