Dan Liew 2cb4223979 [CMake] Support including Git hash and description into the build. 
CMake will automatically pick up changes in git's HEAD so that
the necessary code is rebuilt when the build system is invoked.

Two new options `INCLUDE_GIT_HASH` and `INCLUDE_GIT_DESCRIBE` have been
added that enable/disable including the git hash and the output of `git
describe` respectively. By default if the source tree is a git
repository both options are on, otherwise they are false by default.

To support the `Z3GITHASH` macro a different implementation is used from
the old build system. In that build system the define is passed on the
command line. This would not work well for CMake because CMake
conservatively (and correctly) rebuilds *everything* if the flags given
to the compiler change. This would result in the entire project being
rebuilt everytime git's `HEAD` changed.  Instead in this implementation
a CMake specific version of `version.h.in` (named `version.h.cmake.in`)
is added that uses the `#cmakedefine` feature of CMake's
`configure_file()` command to define `Z3GITHASH` if it is available and
not define it otherwise. This way only object files that depend on
`version.h` get re-built rather than the whole project.

It is unfortunate that the build systems now have different `version.h`
file templates. However they are very simple and I don't want to
modify how templates are handled in the python/Makefile build system.

Dan Liew b5aa6d5eb5 Fix issue with bd1f07f864 pointed out by 
@nunolopes .

If `pthread_cond_signal()` is called while `m_mutex` is held then the
timing thread might be woken up twice due to waking up from
`pthread_cond_timeout()` (due to being signaled) but then being forced
to sleep again because the thread calling `~imp()` is still holding
`m_mutex` (which the timing thread needs to acquire).

Dan Liew bd1f07f864 Fix implementation of scoped_timer under Linux where it was 
incorrectly assumed that `pthread_cond_timedwait()` would exit
due to a condition variable being signaled or a timeout occuring.

According to the documentation `pthread_cond_timedwait()` might
spuriously wake so we introduce a new variable `m_signal_sent` (that is
guarded by an existing mutex) that is used as the variable to check that
the thread wake was not spurious.

This is intended to partially fix #839 .
