* configure.ac: Add the test for Solaris least-privileges. Set
defines for whether capabilities are supported and whether of
the linux or solaris variety.
Add missing-prototypes, missing-declarations, char-subscripts
and cast-qual warnings to default cflags, cause Hasso enjoys warnings,
and we really should clean the remaining ones up. (ie isisd..).
* (*/*main.c) Update the zebra_capabilities_t arrays in the various
daemons to match the changes made in lib/privs.h.
* zebra.h: Solaris capabilities requires priv.h to be included.
* privs.{c,h}: Add support for Solaris Least-Privileges.
privs.h: Reduce some of the abstract capabilities, which do
not have rough equivalents on both systems. Rename the net
related caps to _NET, as they should have been in first
place.
(zprivs_terminate) should take the zebra_privs_t as argument so
that it can update change pointer.
Add an additional privilege state, ZPRIVS_UNKNOWN.
* privs.c: (various capability functions) Add
Solaris privileges variants.
(zprivs_state) Use privs.c specific generic types to
represent various capability/privilege related types, so that
each can be typedef'd as appropriate on each platform.
(zprivs_null_state) static added, to hold the state the null
method should report (should be raised by default, and
LOWERED if zprivs_terminate has been called)
(zprivs_state_null) Report back the zprivs_null_state.
(cap_map) Make it able to map abstract capability to multiple
system capabilities.
(zcaps2sys) Map to abstract capabilities to multiple system
privileges/capabilities.
(zprivs_init) move capability related init to seperate
function, zprivs_caps_init.
(zprivs_terminate) ditto, moved to zprivs_caps_terminate.
Set the change_state callback to the NULL state, so the
user can continue to run and use the callbacks.
