introduce a couple of new turn-off-gcc-warning variables and use them.

GCC 14 has a new annoying calloc() checker that we turn off in a bunch
of places, and there are a few more dangling-pointer issuse that come up,
but seem bogus.

Use double quotes to include the local ./Makefile.hash

terminfo: Add guards to optionally build parts of libterminfo

Reading from a database is now optional.
Compiling terminfo descriptions (including from $TERMINFO) is now optional.
Compat support is now optional.

This removes 17k on amd64 from the binary size, which allows it to be used
again on space constrained ramdisks.

branches: 1.22.32;
These directories default to WARNS?=5

Fix dependencies on generated files.

use the tools version of utilities for other scripts, too

Separate the generators out, so that they can be re-used by tools, and
don't play games with curdir/objdir.

branches: 1.18.2;
Now that nbperf can generate the same file using the -p option,
there is no longer a need to store these files in CVS.

Move longname(3) from curses to terminfo, pre-cursor to fix PR/43386.

Install correct man page links.

Correctly use ti_ instead of t_ for our extensions as per the man page.
Replace vtparm with tiparm.
tiparm is also non standard, but has been proposed at least.

Add termname(3) as defined by POSIX.

document non-literal format strings

remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

libterminfo can now compile a single terminfo description which allows
$TERMINFO to be a terminfo description as well as a file reference.

This enables the user to modify the terminfo description on read-only
media.

Do clean generated terminfo.5 file.

Store the generated compiled terminfo descriptions so that we can build
a consistent library just from source.

Include xterm.

Use $TOOL_TIC

Use structures so we know how long each description is.

Embed ansi, dumb, vt100, vt220 and wsvt25 compiled terminal descriptions
into libterminfo.
Constify some foo.

We should always generate terminfo.5 to save human error syncing.

Store our generated files in CVS and remove nbperf from the toolchain.
This allows us to build consistent libs without an ever changing hash.

Use $HOST_SH instead of calling directly.

Import my terminfo implementation.
This uses the ncurses terminal definitions.

OK: core@, jdc@
