lib/libkvm: start adding basic tests for kvm(3) - kvm_close: add a testcase to verify support for errno = EINVAL / -1 (see D10065) when kd == NULL is provided to the libcall. - kvm_geterr: -- Add a negative testcase for kd == NULL returning "" (see D10022). -- Add two positive testcases: --- test the error case using kvm_write on a O_RDONLY descriptor. --- test the "no error" case using kvm_read(3) and kvm_nlist(3) as helper routines and by injecting a bogus error message via _kvm_err (an internal API) _kvm_err was used as there isn't a formalized way to clear the error output, and because kvm_nlist always returns ENOENT with the NULL terminator today. - kvm_open, kvm_open2: -- Add some basic negative tests for kvm_open(3) and kvm_open2(3). Testing positive cases with a specific `corefile`/`execfile`/`resolver` requires more work and would require user intervention today in order to reliably test this out.

Update the spelling of my name (continuation of r346571) Previous spellings of my name (NGie, Ngie) weren't my legal spelling. Use Enji instead for clarity. While here, remove "All Rights Reserved" from copyrights I "own". MFC after: 1 week 2019-04-22 18:05:33 +00:00			`* Copyright (c) 2017 Enji Cooper <ngie@freebsd.org>`
