martin 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.

lukem 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).

aymeric 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

Remove trailing ; from uses of __weak_alias().  The macro inserts this if
needed.

scw 2a8d425699 After writing a page out to disk, run the page back through the user's 
input filter to ensure we don't end up with a cached copy of the page
in the wrong byte-order for the host cpu.

This fixes a fatal bug which bites when the DB 'lorder' is different
to the cpu's, and a cached page is accessed soon after it was flushed
to disk.

mycroft 648d6d9529 Only squeeze a short key/value pair onto a page with other complete key/value

mycroft 72a2509e35 When deleting a big key, the offset of an empty page should be bsize, not 
bsize-1; otherwise an insertion into the empty page will cause the new key to
be elongated by 1 byte.

mycroft 462e381edd Previous bug fix was slightly wrong. In this case, the data must start on a
