Add initial support for Capsicum's Capability Mode to the FreeBSD kernel,
compiled conditionally on options CAPABILITIES:
Add a new credential flag, CRED_FLAG_CAPMODE, which indicates that a
subject (typically a process) is in capability mode.
Add two new system calls, cap_enter(2) and cap_getmode(2), which allow
setting and querying (but never clearing) the flag.
Export the capability mode flag via process information sysctls.
