6d51085202 Revert "Make sem_wait able to return errno EINTR for sdk > 23."
Broke the build. There's no such file as bionic_sdk_version.h anywhere in the tree.

This reverts commit 892b61d340.

892b61d340 Make sem_wait able to return errno EINTR for sdk > 23.
Posix standards says sem_wait is interruptible by the delivery
of a signal. To keep compatiblity with old apps, only fix that
in newer sdk versions.

dd586f2ebd sem_timedwait with a null timeout doesn't mean "forever".
It actually means "crash immediately". Well, it's an error. And callers are
much more likely to realize their mistake if we crash immediately rather
than return EINVAL. Historically, glibc has crashed and bionic -- before
the recent changes -- returned EINVAL, so this is a behavior change.

23360cc498 Remove invalid left shifts of -1.
Bug: 24492248

Shifting sign bits left is considered undefined behavior, so we need to
switch these uses to unsigned equivalents. The time_t-related code is
updated relative to upstream sources.
