login_cap.h: Remove LOGIN_DEFPRI

This is an implementation detail which is likely to become irrelevant in
the future, as we move to not resetting the priority if the
corresponding capability is not present in the configuration file
('/etc/login.conf').

GitHub's code search and Google show no use of this public constant, and
it doesn't exist in OpenBSD and NetBSD.

So, remove this definition and its sole use in-tree.

login_cap.h: Remove LOGIN_DEFUMASK

This public constant has not been used in-tree since 1997 (this was
noticed while working on previous commit "setusercontext(): umask: Set
it only once (in the common case)").

Since it was an implementation detail and GitHub's code search and
Google show no use of this symbol today, simply remove it.

Summary of login.conf support changes:

o Incorporated BSDI code and enhancements, better logging for error
checking (which has been shown to be a problem, and is therefore
justified, imho); also some minor things we were missing, including
better quad_t math, which checks for under/overflows.

o setusercontext() now allows user resource limit overrides, but
does this AFTER dropping root privs, to restrict the user to
droping hard limits and set soft limits within the kernel's
allowed user limits.

o umask() only set once, and only if requested.

o add _secure_path(), and use in login.conf to guard against
symlinks etc. and non-root owned or non-user owned files being
used. Derived from BSDI contributed code.

o revamped authentication code to BSDI's latest api, which
includes deleting authenticate() and adding auth_check()
and a few other functions. This is still marked as depecated
in BSDI, but is included for completeness. No other source
in the tree uses this anyway, so it is now bracketed with
#ifdef LOGIN_CAP_AUTH which is by default not defined. Only
auth_checknologin() and auth_cat() are actually used in
module login_auth.c.

o AUTH_NONE definition removed (collided with other includes
in the tree). [bde]

o BSDI's login_getclass() now accepts a char *classname
parameter rather than struct passwd *pwd. We now do likewise,
but added login_getpwclass() for (sort of) backwards
compatiblity, namely because we handle root as a special
case for the default class. This will require quite a few
changes elsewhere in the source tree.

o We no longer pretend to support rlim_t as a long type.

o Revised code formatting to be more bsd-ish style.
