63246b1ef4 Ensure dbp is initialized to NULL before trying to use it in an error codepath. 
Detected with gcc -Wuninitialized.
(The bug was introduced in rev 1.13.  Hi Mycroft! :)

340e17eb3b Don't attempt to delete a NULL key. Can happen if we were the only key 
in a 64K page. Thanks to Juergen Hannken-Illjes for the test.

c4e3c4d493 Don't refuse to create a hash database on 0 length files. Treat 
them as new files the same way that the btree code does.  Note that
we do the fstat() after the open() instead of re-using the previous
result of the stat() to avoid races (we open with O_EXLOCK when we care).

bab13a9d96 Revert previous commit at 1.17. a maximum BSIZE of 65536 ends up stored 
as a 0 in the page, but it is supported and it does work.

b7e6351cc4 hash already uses FD_CLOEXEC -- pay attention to the return value and make it 
a hard failure.

Also make btree and recno uses FD_CLOEXEC.

b2f782612f Completely rework how tools/compat is done. Purge all uses/references to 
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.

9f96807631 When storing data size as 32bit int in an overflow page, copy the 
length to a temporary u_int32_t variable and memmove from there to the
final destination - instead of copying the first four 0 bytes from a
64bit variable directly on big endian 64 bit platforms.

This makes sparc64 pass regress/lib/libc/db.

171d653219 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).

b39251c6b2 indx_t can be a 16 bit type, and is thus not suited to hold a difference 
between two pointers in the general case. Replace it by ptrdiff_t.

-> recno databases can now handle records of more than 64KB
-> nvi can now handle files with lines bigger than 64KB
