update README.aix after GH #52
Handle a timeout value of 0 better with TPACKET_V3.

If the user specified a timeout value of 0, and we don't have any
packets to return from pcap_read_linux_mmap_v3(), go back and wait for
packets.  Yes, this means waiting indefinitely, but that's what the
documentation used to say, and what we're making it say again; if this
is a problem, *don't use a timeout value of 0*.

This should fix GitHub libpcap issue #350.

ask for more warnings during a Travis CI build

.travis.yml: add 'touch .devel configure'
Coverity: add the build script used by Travis-CI and Coverity Scan

from https://scan.coverity.com/scripts/travisci_build_coverity_scan.sh
Coverity: customize the build script

- add a 'Verify Coverity Scan run condition' step to avoid multiple runs wit
  Travis matrix.
- add a 'Verify Coverity Scan script test mode' step. if true no uploading,
  avoid reaching the quota. usual processing: false.
- send 'description' as VERSION#SHA (e.g.: 1.6.0-PRE-GIT#c661f8b)
Coverity: update .travis.yml for analysis by pushing in 'coverity_scan' branch
In activate routines, don't pre-set the status; set it for all errors.

This fixes some cases where it wasn't being set properly or at all, and
also means that, as it's not being set initially, compilers that do any
dataflow analysis and report uninitialized variables, and static
analyzers, should report cases where we aren't setting variables correctly.

See GH #352.
Always return 0 on a successful activation.
Merge remote-tracking branch 'bpf/master'

bpf.tcpdump.org and GitHub have diverged again.
Remove BlueZ dependence

Libpcap should not use BlueZ userspace headers, because it does not
use BlueZ at all. It used only Linux kernel, but it does not
provide userspace headers. For compatible reason we should use own copy
of headers and try to dynamically detect Linux kernel version and use
proper structures.
Cleanup some Linux code

Fix some compilator warnings, avoid one using malloc/free
Also various white characters fixes.
