b30ab6d8fe sys/kern sysent: re-add dependency on capabilities.conf
r356868 inadvertently removed this, so changes to capabilities.conf were no
longer considered for being outdated.

05d7dd739c sysent targets: further cleanup and deduplication
r355473 vastly improved the readability and cleanliness of these Makefiles.
Every single one of them follows the same pattern and duplicates the exact
same logic.

Now that we have GENERATED/SRCS, split SRCS up into the two parameters we'll
use for ${MAKESYSCALLS} rather than assuming a specific ordering of SRCS and
include a common sysent.mk to handle the rest. This makes it less tedious to
make sweeping changes.

Some default values are provided for GENERATED/SYSENT_*; almost all of these
just use a 'syscalls.master' and 'syscalls.conf' in cwd, and they all use
effectively the same filenames with an arbitrary prefix. Most ABIs will be
able to get away with just setting GENERATED_PREFIX and including
^/sys/conf/sysent.mk, while others only need light additions. kern/Makefile
is the notable exception, as it doesn't take a SYSENT_CONF and the generated
files are spread out between ^/sys/kern and ^/sys/sys, but it otherwise fits
the pattern enough to use the common version.

1171c633fb Set .ORDER for makesyscalls generated files
When either makesyscalls.lua or syscalls.master changes, all of the
${GENERATED} targets are now out-of-date. With make jobs > 1, this means we
will run the makesyscalls script in parallel for the same ABI, generating
the same set of output files.

Prior to r356603 , there is a large window for interlacing output for some
of the generated files that we were generating in-place rather than staging
in a temp dir. After that, we still should't need to run the script more
than once per-ABI as the first invocation should update all of them. Add
.ORDER to do so cleanly.

af796bfa71 sysent: Reduce duplication and improve readability.
Use the power of variable to avoid spelling out source and generated
files too many times.  The previous Makefiles were hard to read, hard to
edit, and badly formatted.

f22a592111 Convert in-tree sysent targets to use new makesyscalls.lua
flua is bootstrapped as part of the build for those on older
versions/revisions that don't yet have flua installed. Once upgraded past
r354833, "make sysent" will again naturally work as expected.

40018b91dd Don't create pointless backups of generated files in "make sysent".
Any sensible workflow will include a revision control system from which
to restore the old files if required.  In normal usage, developers just
have to clean up the mess.

08e6d9fad8 Continue to introduce Capsicum Capability Mode support:
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.

99d300a1ec - FDESC, FIFO, NULL, PORTAL, PROC, UMAP and UNION file
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.

3cb43dbdaf Generate prototypes for syscall-implementing functions. Put them in
<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.
