Restructure netmap code into generic code and OS-specific support code. Port OS-specific support code to Linux. Linux port tested and seems to work well on Ubuntu 23.10 with netmap kernel modules and drivers added, on arm64 with UTM and vmxnet3. Results for e1000 and e1000e varied due to bad Linux drivers. Untested on bare metal or fast link speeds so far.

Restructure netmap code into generic code and OS-specific support code.
Port OS-specific support code to Linux.
Linux port tested and seems to work well on Ubuntu 23.10 with netmap kernel modules and drivers added, on a arm64 VM with vmxnet3 NIC. Results for virtual e1000 and e1000e NICs varied due to what I root caused to issues with netmap patches for Linux drivers, not with code in ZMap. Untested on bare metal or fast link speeds so far.
Tested to build and run on FreeBSD 14.0, Ubuntu 23.10 and macOS Sonoma, without and with
-DWITH_NETMAPwhere applicable.
