terminfo: v3 records should create v3 aliases

tic: Duplicate and promote v1 records when merging a v3 record

When this occurs, tic merges the matching v1 record into the original v1.

The screen-256color record by itself doesn't have any numerics bigger
than a short, but the xterm+256setaf record does.

The screen-256color record is now as it was before the recent terminfo2.cdb
merge into terminfo.cdb.

tic: free the old buffer after promoting the record type

tic: use EXIT_FAILURE rather than magic numbers

Whitespace

tic: promote record type when merging newer into older

Use the new functions and add more error checking.

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.

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

One more time - do this correctly.

Thanks, joerg.

Wrap the include of sys/endian.h in #ifdef HAVE_SYS_ENDIAN_H to avoid

Since tic is a host tool, we need to include host system header to get
definitions of le16dec() and le16enc().

More adaptation for ports where char is unsigned char.

Store the aliases against the entry, so that infocmp can reproduce them.
