[svn-r14402] Description:
	Add work-around to allow reading files that were produced with a buggy
earlier version of the library, which could create objects with the wrong
object header message count.  There is now a configure flag
"--enable-strict-format-checks" which triggers a failure on reading a file
with this sort of corruption (when enabled) and allows the object to be read
(when disabled).  The default value for the "strict-format-checks" flag is
yes when the "debug" flag is enabled and no when the "debug" flag is disabled.

	Note that if strict format checks are disabled (allowing objects with
this particular kind of corruption to be read) and the file is opened with
write access, the library will re-write the object header for the corrupt
object with the correct # of object header messages.

	This closes bugzilla bug #1010.
