Add a new system call flag, SYF_CAPENABLED, which indicates that a
particular system call is available in capability mode.
Add a new configuration file, kern/capabilities.conf (similar files
may be introduced for other ABIs in the future), which enumerates
system calls that are available in capability mode. When a new
system call is added to syscalls.master, it will also need to be
added here (if needed). Teach sysent parts to use this file to set
values for SYF_CAPENABLED for the native ABI.

syscalls.master for the master list and the Alpha/OSF1 compat ABI to be
consistent with all the other compat ABIs where 'make sysent' already

systems were repo-copied from sys/miscfs to sys/fs.
- Renamed the following file systems and their modules:
fdesc -> fdescfs, portal -> portalfs, union -> unionfs.
- Renamed corresponding kernel options:
FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS.
- Install header files for the above file systems.
- Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland
Makefiles.
All Makefiles now use MACHINE_ARCH for the target architecture.
Unification is required for cross-building.

<sys/sysproto.h> and use them (so far only) in kern/init_sysent.c.
Don't put $Id in generated files.
kern/syscalls.master:
I had to add some new fields to describe some non-orthogonal names.
E.g., the args struct for the syscall-implementing function foo()
is usually named `foo_args', but for getpid() it is named `args'.
sys/sysent.h:
sy_call_t is still incomplete to hide a couple of warnings.
