Filter out collections that are shorter than x milliseconds by using
`ugc -M x`. Display only collections that contain a certain string s
in their description by using `ugc -F s`. The latter option is not
implemented in the kernel, but rather just before printing the event
in the user script (for simplicity), and documented as such.

Fix uobjnew and ustat on python3

Debian jessie .deb build config and automated test fixes.

$ ./ustat
  File "./ustat", line 242
    counts = sorted(counts.items(), key=lambda (_, v):
                                               ^
SyntaxError: invalid syntax

$ ./uobjnew
  File "./uobjnew", line 150
    data = sorted(data.items(), key=lambda (k, v): v.num_allocs)
                                           ^
SyntaxError: invalid syntax

This fixes a TypeError in python 3, e.g, when executing uobjnew

Traceback (most recent call last):
  File "./uobjnew", line 134, in <module>
    bpf = BPF(text=program, usdt_contexts=[usdt])
  File "/usr/lib/python3.5/site-packages/bcc/__init__.py", line 224, in __init__
    text = usdt_text + text
TypeError: can't concat bytes to str

Use fast compression in test deb builds

Builds on GCE/ubuntu image were taking a long time due to combination of
disk speed/single core, and the default dpkg-deb compression level
(-z9). The dpkg-deb alone step was taking up to 5 minutes. Reduce to ~1
minute by forcing -z1. Unfortunately, it was not obvious how to capture
the option in debuild command, so this is a bit hacky.

In python3, output needs to be converted from ascii to str before the
"error_msg in str" test will succeed. This change should be backwards
compatible with python2.

Recent llvm changed the calling convention of setInvocation, breaking

Without marking as nounwind, recent llvm started generating .eh_frame
section, which is invalid for bpf target jit.

snapcraft: add in some missing tools from the snapcraft apps list

tplist: don't fail if no verbosity is supplied

update tools pic

Initialise the verbosity argument to 0, so that when no verbosity is
provided we don't fail with

Minor debian/control file updates
Added Debian - Source section to INSTALL.md

On 30 April 2016 Vicent Marti modified src/lua/CMakeLists.txt to
statically link libbcc into bcc-lua.  This causes one of the tests
in test/lua/test_standalone.sh to fail, and renders all of the tests
related to libbcc.so obsolete.

xrange does not exist in py3.

Add in capable, deadlock-detector, llcstat, mountsnoop, profile,
runqlen, solisten, tplist, ucalls, uflow, ugc, uobjnew, ustat
and uthreads. Includes some re-ordering as well.

It turns out that for FC24 and FC25, there is a sufficiently recent
version of Clang in the official package sources, so we don't need
to fetch it from llvm.org using wget. Tested manually on a pair of
fresh FC24 and FC25 VMs, and confirmed that BCC builds and runs OK.
