[netbsd] Get device numer of tmpfs instead of reporting zero
[openbsd] Rewrite OpenBSD support because OpenBSD disallows
kernel memory access and lsof has to switch to user mode API.
Currently, most features are working, but file path reporting
and lock status are not working for lack of kernel support.
As a consequence, OpenBSD dialect is separated in a new folder.
[darwin] Remove /dev/kmem backend because it no longer exists on
current macOS releases. Use libproc backend instead.
[linux] Do not hard-code fd numbers in epoll test, fixing tests
on Void Linux
[freebsd] Use kf_file_nlink if provided by kernel instead of
stat(). This commit requires kernel with
https://reviews.freebsd.org/D38169. It brings back the ability
to list deleted files via `lsof +L1`. Closes #264.
[linux] Add --with-selinux configure option.
[solaris] Re-introduce support for recent Solaris & OpenIndiana
releases.
[darwin] Display kern ctl info, learned from apple lsof version.
[linux] Improve performance by using closefrom(). Closes #281.
[aix] Fix compilation on AIX 7.2 and add autotools build system
support for AIX.
[aix] Suppress warnings properly on AIX version greater than
5.0. Closes #187.
Introduce alpha version of liblsof which allows users to use
lsof functionality via C functions instead of spawning a
subprocess and parsing the output. This version may contain BUGs
and memory leaks, and the API may change before it stablizes.
