netmap: set IFCAP_NETMAP in if_capabilities
Revision r307394 removed (by mistake) the code that sets IFCAP_NETMAP
in if_capabilities on netmap_attach. This patch reverts this change.

netmap: align codebase to the current upstream (sha 8374e1a7e6941)
Changelist:
- Move large parts of VALE code to a new file and header netmap_bdg.[ch].
This is useful to reuse the code within upcoming projects.
- Improvements and bug fixes to pipes and monitors.
- Introduce nm_os_onattach(), nm_os_onenter() and nm_os_onexit() to
handle differences between FreeBSD and Linux.
- Introduce some new helper functions to handle more host rings and fake
rings (netmap_all_rings(), netmap_real_rings(), ...)
- Added new sysctl to enable/disable hw checksum in emulated netmap mode.
- nm_inject: add support for NS_MOREFRAG

r337812 also fixed a bug in the netmap kevent code. The inclusion of
that fix was an oversight that I didn't notice until this
MFC. Reference the code review and PR here in the MFC for
completeness.

o Restore netmap emulation mode to working order, including
fixing the destructor panics on detach.
o Omit pipe additions to these fixes, likely problematic for
Suricata to pass traffic like it does on 11.0 without this
patch.
o Allow to build the module without errors in the tree.
Many thanks to Vincenzo Maffione for assistance and review! :)
