it from being used as input.

Write the database file into a temporary file first, because otherwise if
we don't specify an output filename, the database file we create will end
up being used during population as the database file to find entries quickly.

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

safer use of realloc

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

Avoid cgetcap &co prototypes conflicting with those provided by the host.
With this change we can cross-compile on FreeBSD 4.x.

Make this compilable as a host tool.

Examine input files and set the openinfo hint accordingly to number of
found records. This makes resulting db for small capability databases
much smaller - for vgrind(1), the resulting vgrindefs.db is about 24KB
instead of ~500KB.

The hint passed to dbopen() is number of records in input files
rounded up to nearest power-of-two value and multiplied by two.
Besides being a nice conservative value, termcap.db become about
70KB bigger if the hint matches the count of records (1023), probably
due to hash overflows.
