Clarify that Condition::wait() can spuriously wake up
Also, remove the clarification that Condition::signal() wakes exactly
one thread as in the presence of spurious wake ups, this clarification
does not provide a safe guarantee to developers.

Make Condition use CLOCK_MONOTONIC
Changes to the REALTIME clock can cause Condition::waitRelative() to
timeout early or delayed. This behavior is undesired and new since
https://android-review.googlesource.com/#/c/181058/ moved the
underlying pthread_cond_timedwait() implementation to use absolute
timeouts rather than relative ones. Having Condition use
CLOCK_MONOTONIC prevents these timeout issues.

Exporting C++ headers from system/core
Moved headers from include/libutils and include/libsysutils to
libutils/include and libsysutils/include respectively, so they can be
exported via these libs. They needed to be moved since Soong does
not allow export from external folder.
Added symlink from old locations. They are needed since Soong
includes system/core/include by default. Once all modules are
cleaned up to explicitly add the required libs, the symlinks will be
removed.
Moved headers of libutils to libutils_headers. They should be used
by modules for header-only inlines. Added libutils_headers as
dependency of libutils.
Split of C++ headers into those that have no dependency and those that
have dependency on libutils.so will be handled in a later CL.
Test: Add above libs to shared lib of local module
