Put the libbabeltrace-ctf specific parts of babeltrace.pc into a babeltrace-ctf.pc file

On some distributions libbabeltrace and libbabeltrace-ctf are packaged
into separate packages. This means they should have their own pkg-config
file.

The babeltrace-ctf.pc file requires the babeltrace.pc one.

With this change, to have the ctf support in libbabeltrace a pkg-config
user will need to specify the babeltrace-ctf package. To compile and
link with only the base libbabeltrace, the package babeltrace would be
used.

Some old compilers do not use C99 as their default C language variant,
for example gcc 4.3.x, which is used on some old machines. When such a
compiler is used, by default, ULLONG_MAX is not visible. Adding
-std=gnu99 is needed to make this definition visible.

In autoconf speak, this translates into the need of using
AC_PROC_CC_STDC instead of AC_PROG_CC. See

Add a new option --clock-offset-ns. It requires a parameter

This works exactly as the option --clock-offset, except that

The two options --clock-offset and --clock-offset-ns are
compatible with each other, and it's possible to give both.
For example, having the options
