Change the linuxerr.ErrorFromErrno to return an error type and not
a *errors.Error type. The latter results in problems comparing to nil
as <nil><nil> != <nil><*errors.Error>.
In a follow up, there will be a change to remove *errors.Error.Errno(),
which will also encourage users to not use Errnos to reference linuxerr.

Removes package syserror and moves still relevant code to either linuxerr
or to syserr (to be later removed).
Internal errors are converted from random types to *errors.Error types used
in linuxerr. Internal errors are in linuxerr/internal.go.

Update all instances of the above errors to the faster linuxerr implementation.
With the temporary linuxerr.Equals(), no logical changes are made.

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.

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.

Change the p9 server to use *errors.Error defined in pkg linuxerr. Done
separate from the client so that we ensure different p9 server/client versions
work with each other.
