[syserror] Update syserror to linuxerr for EACCES, EBADF, and EPERM.
...
Update all instances of the above errors to the faster linuxerr implementation.
With the temporary linuxerr.Equals(), no logical changes are made.

[syserror] Change syserror to linuxerr for E2BIG, EADDRINUSE, and EINVAL
...
Remove three syserror entries duplicated in linuxerr. Because of the
linuxerr.Equals method, this is a mere change of return values from
syserror to linuxerr definitions.
Done with only these three errnos as CLs removing all grow to a significantly
large size.

[syserror] Add conversions to linuxerr with temporary Equals method.
...
Add Equals method to compare syserror and unix.Errno errors to linuxerr errors.
This will facilitate removal of syserror definitions in a followup, and
finding needed conversions from unix.Errno to linuxerr.

[syserror] Refactor linuxerr and error package.
...
Move Error struct to pkg/errors package for use in multiple places.
Move linuxerr static definitions under pkg/errors/linuxerr.
Add a lookup list for quick lookup of *errors.Error by errno. This is useful
when converting syserror errors and unix.Errno/syscall.Errrno values to
*errors.Error.
Update benchmarks routines to include conversions.
The below benchmarks show *errors.Error usage to be comparable to using
unix.Errno.
