db66d7c5ea Add support for npcap as winpcap replacement 
For now both winpcap and npcap are supported with the latter being
experimentally supported till we get some feedback from users and
confirm that things are all working fine with npcap.

OID for link state has been changed to one that supports both.

To check which is being used, run 'drone -v'.

Fixes #236

176fc7dd15 Redo fix for incorrect vlan parsing of rx emuldev frames 
The previous fix in 6977278654 was incorrect and incomplete since it
won't handle the case when emulated devices have PRIO and/or CFI/DEI
set.

This is the correct fix where Prio and CFI/DEI are no longer part of the
device key.

f0dd0c307b Fix device emulation crash due to contention 
Device emulation packets are received and processed in a different
thread compared to the main RPC processing thread where the emulated
devices are created/deleted. No packets should be processed while the
latter is in progress otherwise the former may access devices that have
been deleted.

64d1525f50 Fix infinite loop when stopping capture etc. 
On some platforms and/or some libpcap verisons, libpcap doesn't support a
timeout which makes interactive stop not possible. So we now use a UNIX
signal to break out. Obviously this works only on *nix platforms - which
includes MacOS. For now the problem is not seen on Windows with WinPCAP,
so we should be fine. May need to revisit when we add Npcap support.

Fixes #215, #234

adfe1380da Print drone version/revision first thing at startup 
Currently these are printed at the end of init when we start waiting for
client connections - this was done so that this info doesn't get lost in
the barrage of init logs. The downside is if there is a crash during
init, we don't get to know the version/revision from the logs. With this
change this info is printed twice - first thing when we start and just
after init when we start waiting for client connections

1cddfbf2ec Use Windows' connection name as the port description 
... instead of the PCAP returned description. This allows for a better
UX since user can more easily identify which port is which.

This will work only Windows Vista and higher since IPHLPAPI.DLL has
published APIs only for these versions. Older windows versions such as
XP will continue to use the PCAP returned description
