Document nanosecond-resolution pcap files.
Rename the "private" member of a pcap_t to avoid C++ issues.

"private" is a C++ keyword; rename the "private" member of a pcap_t to
"priv" to avoid that, as per Gisle Vanem's suggestion.
Declare pcap_get_adapter() on Win32.
Add stream support to dag_create()

DAG capture device names are of the format dagN or dagN:M where N
is the device number and M is the stream number. The former implies
stream 0.

Fix DAG Stream support in dag_create()
man: add documentation for pcap_set_tstamp_precision
man: add documentation for pcap_get_tstamp_precision
build-sys: add time stamp precision man pages
linux: remove dead code
linux: fix initialization of tstamp_precision_list

We should be using tstamp_precision_list to store time stamp precisions
which we support.

Add documentation and fix SIGSEGV when using pcap_set_tstamp_precision
Fix (unlikely) memory leak.

If we were able to allocate the list of time stamp types, but were
unable to allocate the list of time stamp precisions, free the list of
time stamp types before freeing the handle.
