Evgeniy Stepanov 4af9c0ea80 [asan] i686-linux-android support. 
Large part of this change is required due to
  https://code.google.com/p/android/issues/detail?id=61799
dlsym() crashes when symbol resolution fails, which means
we have to limit the interceptor list instead of relying on
runtime detection.

There are minor differencies in system headers, too.

Evgeniy Stepanov f532c5bfd5 [sanitizer] Remove the definition of xdr_ops. 
User-visible instances of xdr_ops always seem to be allocated statically, and
don't need unpoisoning. Also, it's size differs between platforms.

Evgeniy Stepanov 86a4d2c32b [sanitizer] Intercept fgetpwent / fgetgrent. 
These interceptors require deep unpoisoning of return values.
While at it, we do the same for all other pw/gr interceptors to
reduce dependency on libc implementation details.

Instead of checking stack limits that are not well defined for the main thread,

Evgeniy Stepanov 39cc337e20 [sanitizer] Change the way we use certain linux kernel headers. 
Some linux headers are broken on older kernels.
Instead of depending on the constants and types from such headers directly,
we provide our own definitions and then verify them with compile-time
assertions. This makes the dependency on the headers test-only and would allow
switching to some other way of testing on older kernels, or even disable the
tests as the last resort (after all, kernel interfaces are supposed to be
stable).
