Add proper debian build support, rename libbcc.so

improve examples using new features

This adds support for properly tagging the build when cmake is run not
in a git tree, which is the case when building from src-deb.
Signed-off-by: Brenden Blanco <bblanco@plumgrid.com>

The cmake based build system is nice, but not quite production ready.
Move to the more painful but featureful debuild style. This is one step
towards an upstreamable package.

Rename libbpfprog (ugh) to libbcc.

Split out python-bpf and libbcc-examples into separate packages that
depend on libbcc.

Add debug flag to enable prints from kernel verifier

Signed-off-by: Brenden Blanco <bblanco@plumgrid.com>

Add flag to BPF() to enable debug prints from the verifier. Use by
passing 0x2 to debug= in the constructor. Add docstring for BPF
constructor.

Also, optimize bpf_prog_load so that by default the kernel is not
asked to print the verbose output. The program will be "loaded" a second
time to capture the verifier failure message.
