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

it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.

- 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

support for older compilers

Introduce a bunch of inline functions and utilities to avoid code duplication.

As described in tech-userlevel:
- Modify the writing code to only write entries in the new
format for the terminal descriptions that require it.
- Store new format entries as <name>@v3
- Store old format entries with clamped values as <name> for
backwards compatibility
- Lookup first <name>@v3 and then <name> if that is not found.
- Don't create terminfo2 anymore; old programs keep working with
clamped entries, and new programs be able to use the wide
fields with using the original db file.

terminfo: promote numeric parameters from short to int

POSIX mandates implementations must support upto a short but may exceed it.
When NetBSD terminfo was implemented, no terminfo description used over
a short, but because ncurses has supported ints for some time, some now do.

Infact, such a terminfo description was imported where colour pairs for
screen-256color went up to 65536 which exposed a bug in the existing
implementation where it set to zero. Because the number might mean
something more than a range, we need to be able to store it accurately.

This requires a version bump because whilst the API hasn't changed thanks
to C int promotion, the ABI has. Also the underlying database structure
has changed as well - we now store the numeric paramter inside a uint32_t
field rather than a uint16_t one.
Whilst this change can still read the old style database, the old one
cannot read the new one and thus we now maintain the database as
terminfo2.cdb, leaving the old library and database alone so old programs
still work fine.

libcurses, libfrom, libmenu and libpanel have also been bumped to
accomoate this change.

There is no standard way of getting a list of aliases for the

PR/50092: Rin Okuyama: Fix memory leak.

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.

PR/45370: Takehiko NOZAKI: termcap emulation tget{flag,num,str} should
work with non-NUL terminated strings.

Simplify some conversion by usig pre formatted strings and a function
to print a parameter.

revert OOPS change now that most of the reasons for tgoto to return NULL
have been eliminated.

Add support for translating the following termcap commands into terminfo:
%B %D %r %2 %3 %d %+ %> %.
Fixes PR bin/44692.

Restore historical behavior of tgoto() to return "OOPS" on failure. This is
best for now because there are too many programs that don't check the return
value of it. Of course cursor motion commands from $TERMCAP have 0 chance
of working now, since their % escapes are not translated to terminfo. In
the window case %+ expects one param from the stack in the termcap case
and two in the terminfo so we barf. We need proper captoinfo handling for
the % escapes, like the one in ncurses. Hi Roy :-)

PR/43961: YAMAMOTO Takashi: uninitialized variable in termcap.c
Remove dead code.

Our API just uses typedefs, so don't use the struct symbol which will avoid
any potential conflicts with userland.

Convert padding for unknown capabilities as well.

Convert padding and give terminfo some default assumptions about termcap.

Use _ti_get_token instead of strsep when parsing termcap entries.
This allows us to handle \E\ as a valid sequence.

Escape , when converting to terminfo.

Implement captoinfo so that we can convert $TERMCAP into $TERMINFO.
We don't currently map %> %B %D.

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

libterminfo: remove redundant lint annotations

Since 2021-02-28, lint does not warn about constant conditions if they
involve sizeof.

The fallthrough annotations have never been necessary for case labels
that directly follow each other.

As described in tech-userlevel:
- Modify the writing code to only write entries in the new
format for the terminal descriptions that require it.
- Store new format entries as <name>@v3
- Store old format entries with clamped values as <name> for
backwards compatibility
- Lookup first <name>@v3 and then <name> if that is not found.
- Don't create terminfo2 anymore; old programs keep working with
clamped entries, and new programs be able to use the wide
fields with using the original db file.

Move the strings vs long analysis to a private function, but allow
tput(1) to use it so we can work with string parameters to capabilities.

As tparm accepts longs we should treat them as long during expansion.
