This change moves everything depending on kernel headers (mostly ioctl types

header conflict on various platforms (most importantly, older glibc versions).
This change also removes 2 deprecated ioctls, and symbolic ids for other bunch
of ambiguous ioctls (i.e. same id is shared by ioctls with different memory
behavior).

DataFlowSanitizer is a generalised dynamic data flow analysis.
Unlike other Sanitizer tools, this tool is not designed to detect a
specific class of bugs on its own. Instead, it provides a generic
dynamic data flow analysis framework to be used by clients to help
detect application-specific issues within their own code.

[TSan] Let the users suppress use-after-free errors using the "race:" suppressions.
...
If there's a race between a memory access and a free() call in the client program,
it can be reported as a use-after-free (if the access occurs after the free()) or an ordinary race
(if free() occurs after the access).
We've decided to use a single "race:" prefix for both cases instead of introducing a "use-after-free:" one,
because in many cases this allows us to keep a single suppression for both the use-after-free and free-after-use.
This may be misleading if the use-after-free occurs in a non-racy way (e.g. in a single-threaded program).
But normally such bugs shall not be suppressed.

Revert "[sanitizer] Intercept sched_getaffinity."

This reverts commit r187788.
The test case is unreliable (as the test may be run in a situation in
which it has no affinity with cpu0). This can be recommitted with a more
reliable test - possibly using CPU_COUNT != 0 instead (I wasn't entirely
sure that a process was guaranteed to have at least one affinity, though
it seems reasonable, or I'd have made the change myself).
