configure: Add --enable-code-profiling and --enable-code-coverage flags.

Browse Source 
These configure flags enable code profiling (with gprof) and code
coverage (with gcov) respectively.

Although this is a nice idea, it's not currently very useful.

Libtool mangles filenames in such a way that gcov cannot locate its
datafiles.

Profiling is of dubious utility with libguestfs which is not CPU-bound
and relies extensively on running external programs (oprofile-like
system profiling that took into account libguestfs + qemu or
libguestfs + qemu + the appliance + filesystem tools *would* be
useful).

Also neither flag will help in capturing data from the appliance.
